Obesity is a multifactorial disease linked to many comorbidities and has an impact on brain health. It is also known that obesity disrupts the endocannabinoid (eCB) system in the central nervous system and in the periphery, which complicates the underlying mechanisms behind obesity. However, weight loss through lifestyle interventions or bariatric surgery may alleviate obesity-related comorbidities, as well as restore eCB tone. Several studies have reported a decrease in circulating eCBs following weight loss, likely due to the positive association of these mediators with fat mass. However, further research is needed to clarify whether this reduction is a consequence of weight loss or plays a role in facilitating it. This review explores changes in circulating eCBs following weight loss and their potential roles in cerebral homeostasis and the reward system. It examines how lifestyle modifications and bariatric surgery may influence central eCB signalling and contribute to long-term weight loss success. Understanding the mechanisms behind improved brain function after weight loss could provide insights into optimizing obesity treatments.

The glucocorticoid receptor alpha (GRα), a vital component of the ancient glucocorticoid (GC) signaling system, is essential for vertebrate survival. It regulates fertility, fetal development, organ function, vascular and neural integrity, metabolism, immune responses, and stress adaptation. While GRα’s anti-inflammatory properties have been acknowledged since the mid-20th century, its crucial role as the master regulator of homeostatic corrections in both health and critical illness has only recently come to light. In critical illness, GRα facilitates a seamless transition through three essential phases of homeostatic correction. Initially, in the Priming Phase, it activates immune responses and mobilizes energy reserves to defend against stressors like infection and injury, enhancing glucose metabolism, supporting mitochondrial function, and strategically deploying immune cells to areas of damage. Next, during the Modulatory Phase, GRα fine-tunes inflammatory responses, manages oxidative stress, regulates vascular tone, and maintains cellular integrity. Finally, in the Restorative Phase, GRα plays a crucial role in resolving inflammation, initiating tissue repair, supporting cellular regeneration, facilitating debris clearance, and reestablishing anatomical and physiological balance for long-term recovery. GRα coordinates complex molecular interactions, including co-regulation with pro-inflammatory transcription factors, ensures mitochondrial stability, and metabolic balance under stress. However, depleted bioenergetic and micronutrient reserves in critically ill patients can impair GRα’s capacity, increasing morbidity and mortality risks. This review highlights the need to reassess current GC treatment strategies and integrate micronutrient support to optimize GRα function. Such an approach could strengthen immediate immune defenses, enhance long-term recovery, reduce GC dose and duration, and minimize adverse effects.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is rapidly emerging as a global health crisis, affecting over 30% of the population and demanding urgent attention. This redefined condition, previously known as non-alcoholic fatty liver disease (NAFLD), reflects a deeper understanding of the intricate interplay between metabolic dysfunction and liver health. At the heart of MASLD lies the troubling accumulation of triglycerides (TGs) in hepatocytes, which precipitates insulin resistance and oxidative stress, ultimately leading to more severe forms like metabolic dysfunction-associated steatohepatitis (MASH). Excitingly, recent research has spotlighted the farnesoid X receptor (FXR) as a groundbreaking therapeutic target. FXR not only regulates lipid metabolism but also combats inflammation and insulin resistance, making it a potential game-changer in the fight against MASLD. With only one FDA-approved drug, resmetirom, currently available, the exploration of FXR agonists opens new avenues for innovative treatments that could revolutionize patient care. By harnessing the power of FXR to restore metabolic balance and integrating advanced strategies like lipidomics and fatty acid profiling, we stand on the brink of transforming how we approach MASLD and its associated complications, paving the way for a healthier future. This review delves into the promising role of FXR in combating MASLD and its implications for related metabolic disorders, emphasizing the urgency for advanced strategies to detect and manage this burgeoning epidemic.

The accumulation of adipose tissue is associated with metabolic disorders, including insulin resistance, type 2 diabetes (T2D), dyslipidemia, metabolic syndrome, and cardiovascular diseases (CVD). Menopause might predispose women to increase body weight and adipose tissue, and decrease lean muscle mass. Furthermore, postmenopausal women display fat mass redistribution with greater accumulation in the visceral area mainly due to hormonal shifts that result in a higher testosterone/estradiol ratio. These effects are associated with a less favorable adipokine profile, dyslipidemia, insulin resistance, and cardiac dysfunction after menopause. Fat mass is determined by the balance between the storage of triacylglycerol (TAG) (lipogenesis) and the removal of stored TAG (lipolysis) in combination with the differentiation of new adipocytes (adipogenesis). Disturbances in adipose tissue dynamics lead to an increase in lipogenesis (hypertrophy) and/or in adipogenesis (hyperplasia) to accommodate excess energy intake. While large adipocytes are dysfunctional and have greater secretion of inflammatory adipocytokines, small adipocytes are healthier and associated with metabolic improvements. Different strategies can be used to prevent or reduce body weight gain and fat mass, as well as to maintain healthy adipose tissue; however, due to robust evidence, lifestyle interventions should be pillars in this process. This review provides a comprehensive summary of findings on the role of a balanced diet and physical exercise in improving body composition and promoting healthy adipose tissue in postmenopausal women.

Metabolic disorders are due to a deficiency of enzymes, which can severely impact health or cause serious complications without treatment. This study aimed to identify the molecular causes of an infant death who had been hospitalized with complicated health problems and metabolism syndrome. Whole-exome sequencing (WES) was used to screen pathogenic variants in the patient’s genome, followed by examination of variants segregation in her parents. The WES analysis identified two homozygous variants, c.[614C>G; 649A>G] in the HMGCL gene of the patient. These two variants co-locate within the exon 7 of the HMGCL gene, resulting in 2 amino acid substitutions, p.[T205S; M217V], in the conservative region of enzyme protein. Sanger sequencing showed that the patient’s unaffected mother and father carried one mutant allele of the HMGCL gene containing two c.[614C>G; 649A>G] variants. The HMGCL gene encodes the 3-hydroxy-3-methylglutaryl-CoA lyase enzyme, which is critical in the ketogenic pathway. The deficiency of this enzyme was reported to be a life-threatening illness in the neonatal period, and two variants detected in this study were also found in a Japanese patient with sudden, unexpected death in infancy. The frequency of these two variants in the Vietnamese in-hour database and their further functional analysis were also reported in this study. The results of this study have explored the molecular etiology that causes the severe, deadly condition of the patient and provide an understanding of the risk of disease in her family.

Type 2 diabetes mellitus (DM) and hypertension (HT) are common major cardiovascular disease (CVD) risk factors. They share common pathophysiological mechanisms and are commonly co-existent. Prevalence of HT is increased among diabetic patients but also DM is more common in hypertensive patients. CVD risk increases multiplicatively in coexistence of HT and DM. Lowering blood pressure (BP) has been shown to be associated with improved morbidity related to both macro- and micro-vascular complications. Although there is debate about target BP levels, in many randomized controlled trials and guidelines a goal of < 130/80 mmHg is advocated in patients with DM, if well tolerated. However, an individualized approach should be cared for depending on risk factors, co-morbidities, and frailty of patients. Lifestyle modifications including weight loss, regular exercise, avoiding smoking and excessive alcohol consumption, and a healthy diet including limitation of salt and fat and total energy intake, are important both as a part of preventive therapy and treatment modality for both DM and HT. Among antihypertensive drugs angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin receptor blockers (ARBs) are warranted due to their potential advantages for slowing albuminuria and progression to kidney failure which is more common in DM. Usually, their combination with calcium-channel blockers (CCBs) or thiazide/thiazide-like diuretics, in a step-wise manner, is recommended. Resistant HT is more common in DM and requires the addition of mineralocorticoid receptor antagonists (MRAs). New antidiabetic drugs like glucagon-like peptide 1 (GLP-1) agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors have been found to lower BP. Apart from their antihypertensive effects they also improve CVD and renal outcomes. There’re ongoing new trials for new agents. Development of more potent and longer-term effective BP lowering drugs, single pill multiple drug combinations of antiHT agents and combination of antiHT agents with glucose-lowering and antilipidemic agents will probably improve compliance to treatment and achievement of goals in diabetic patients.

The escalating prevalence of diabetes poses a significant health concern. Uncontrolled diabetes leads to a multitude of complications. A comprehensive management plan and continual adaptation of guidelines is needed. The American Diabetes Association (ADA) is a guiding force in this domain, providing diabetes care recommendations for clinicians, laboratorians, researchers, and policymakers since 1989. The latest ADA guidelines present both challenges and opportunities for laboratories. The increased emphasis on glycated hemoglobin (HbA1c) testing for early diagnosis and personalized monitoring is expected to increase testing volumes, potentially leading to a rise in point-of-care testing. Ensuring standardized testing procedures becomes paramount to maintaining consistent and reliable results across laboratories. Moreover, laboratories may need to expand their test menus to accommodate the growing demand for personalized medicine approaches and collaborate closely with healthcare providers to support informed decision-making. This commentary provides a focused analysis of the 2024 ADA guidelines for the laboratory assessment of diabetes.

Current diabetes guidelines recommend people with gestational diabetes mellitus (PwGDM) use primarily blood glucose meters (BGM) for diabetes management. We evaluated glycemic trends and guideline-recommended glycemic targets achieved in PwGDM using a diabetes app with a family of Bluetooth® connected BGMs.
Anonymized glucose and app analytics data from 26,382 PwGDM were sourced from a server. Data from their first 7-days using the app with connected BGMs was compared to 7-days prior to a 10-week timepoint.
Percent fasting readings in range (RIR, < 5.3 mmol/L) improved by +20.3 percentage points in the overall population. Improved glucose RIR (3.5 to 7.8 mmol/L) (+8.3 percentage points), mean blood glucose (BG, –0.59 mmol/L), and fasting RIR (+33.2 percentage points) were observed in those with baseline mean BG ≥ 6.1 mmol/L. Improvements in mean BG of –0.32 to –2.36 mmol/L, and RIR of +3.0 to +38.3 percentage points correlated with higher baseline mean BG ≥ 6.1 to ≥ 7.8 mmol/L. Only 58.5% of PwGDM with baseline mean BG ≥ 6.1 mmol/L had > 80% RIR at baseline, which improved to 79.5% at 10 weeks. PwGDM averaged 17 app sessions and 90 minutes per week on the app.
PwGDM engaged with the diabetes app and connected BGM, facilitating attainment of glycemic targets, an especially important outcome for those with higher mean glucose at baseline.

A 74-year-old male patient with beta thalassemia minor presented in 2022 for a follow-up of osteoporosis diagnosed prior to 2004. At the time of presentation, his medical history included: radiation exposure to his head and neck, goiter, prostate cancer status post resection in 2019 without a history of anti-androgen therapy, and atrial fibrillation, for which he had been prescribed apixaban since 2021. Treatment with risedronate occurred from approximately 2004 to about 2011, with improvement in bone density to osteopenia. He had also taken vitamin D and calcium supplementation and engaged in regular weight-bearing exercise. The patient had no other known risk factors for decreased bone mineral density preceding the onset of his osteoporosis, and a previous workup for secondary causes of his osteoporosis etiology proved negative. We propose that beta thalassemia minor is potentially a risk factor for osteopenia and osteoporosis, and that bisphosphonates can be considered for management when therapeutic intervention is indicated. Even in the absence of other known risk factors, clinicians should consider periodically screening beta thalassemia minor patients with DXA for evaluation of bone health.

Stress hormones, namely glucocorticoids, have diverse actions throughout the body in regulating development, tissue metabolism, inflammation, circadian rhythms, and skeletal homeostasis. While endogenous glucocorticoid levels are important to support bodily homeostasis, chronically elevated levels can cause damage to tissues and drive diseases including bone loss (i.e., osteoporosis), myopathy (i.e., sarcopenia) and metabolic disturbances (i.e., glucose intolerance, diabetes, and abnormal fat accrual). There is substantial evidence that basal glucocorticoid levels increase during ageing while at the same time the amplitude of the diurnal variation in glucocorticoid secretion decreases. However, the significance of these changes for skeletal health is not well understood and has only recently been studied in more detail. Evidence from genetically modified mouse models indicates that changes in glucocorticoid signaling associated with ageing induce bone loss, sarcopenia and drive osteoarthritic joint disease. These studies provide important insights into the role of glucocorticoids in age-related skeletal diseases which will aid in the development of novel treatments especially needed for osteoarthritis which disproportionally affects the elderly.

Adult-onset testosterone deficiency (TD) in men is diagnosed by the finding of low serum testosterone levels and recognised, associated symptoms. The condition has high prevalence in men over 50 years of age, particularly those with type 2 diabetes (T2DM). Accumulating data show adult-onset TD is associated with increased mortality risk. We review the literature and consider the evidence suggesting testosterone therapy (TTh) reduces mortality, especially in men with T2DM. We previously reported that in the Burntwood Lichfield Atherstone Sutton Coldfield Tamworth (BLAST) study screened cohort of men with adult-onset TD and T2DM adult-onset TD was associated with increased mortality with TTh decreasing this higher mortality. The data hinted that the effect was greater in older men. We confirmed this observation with statistical analyses to study the effect of age on the association between adult-onset TD and mortality; Cox regression analysis demonstrated that the reduced risk (hazard ratio: 0.61, 95% CI: 0.38–0.96) following TTh was restricted to men above the median age of 65.89 years. Finally, we speculate on putative mechanisms that may mediate these associations. Heterogeneity in men with adult-onset TD is expected in view of its definition of low testosterone levels together with associated clinical phenotypes that are not always directly related. Many of these classifying phenotypes are associated with increased mortality. Thus, it is perhaps possible that mechanism(s) of all-cause mortality reduction following TTh is via the impact on these associated phenotypes such as the metabolic syndrome (MetS), hyperglycaemia, hypertension, dyslipidaemia, low haematocrit, sex hormone binding levels, erectile dysfunction, etc. We propose that further research studying the effect of TTh takes heterogeneity into account.

The increased emphasis on glycated hemoglobin (HbA1c) testing for early diagnosis and personalized monitoring is expected to increase testing volumes, potentially leading to a rise in point-of-care testing. Ensuring standardized testing procedures becomes paramount to maintaining consistent and reliable results across laboratories. Moreover, laboratories may need to expand their test menus to accommodate the growing demand for personalized medicine approaches and collaborate closely with healthcare providers to support informed decision-making.

While endogenous glucocorticoid levels are important to support bodily homeostasis, chronically elevated levels can cause damage to tissues and drive diseases including bone loss (i.e., osteoporosis), myopathy (i.e., sarcopenia) and metabolic disturbances (i.e., glucose intolerance, diabetes, and abnormal fat accrual). There is substantial evidence that basal glucocorticoid levels increase during ageing while at the same time the amplitude of the diurnal variation in glucocorticoid secretion decreases. However, the significance of these changes for skeletal health is not well understood and has only recently been studied in more detail. Evidence from genetically modified mouse models indicates that changes in glucocorticoid signaling associated with ageing induce bone loss, sarcopenia and drive osteoarthritic joint disease. These studies provide important insights into the role of glucocorticoids in age-related skeletal diseases which will aid in the development of novel treatments especially needed for osteoarthritis which disproportionally affects the elderly.
A 74-year-old male patient with beta thalassemia minor presented in 2022 for a follow-up of osteoporosis diagnosed prior to 2004. At the time of presentation, his medical history included: radiation exposure to his head and neck, goiter, prostate cancer status post resection in 2019 without a history of anti-androgen therapy, and atrial fibrillation, for which he had been prescribed apixaban since 2021. Treatment with risedronate occurred from approximately 2004 to about 2011, with improvement in bone density to osteopenia. He had also taken vitamin D and calcium supplementation and engaged in regular weight-bearing exercise. The patient had no other known risk factors for decreased bone mineral density preceding the onset of his osteoporosis, and a previous workup for secondary causes of his osteoporosis etiology proved negative. We propose that beta thalassemia minor is potentially a risk factor for osteopenia and osteoporosis, and that bisphosphonates can be considered for management when therapeutic intervention is indicated. Even in the absence of other known risk factors, clinicians should consider periodically screening beta thalassemia minor patients with DXA for evaluation of bone health.

Pheochromocytomas (PCCs) and paragangliomas (PGLs; together PPGLs) are uncommon neuroendocrine tumors arising from adrenal medullary chromaffin cells and sympathetic/parasympathetic paraganglia. Though PPGLs predominate in adult populations, pediatric cases of PPGLs represent more aggressive disease outcomes with 12% being diagnosed as metastatic. Metastatic disease (spread to bone, lung, lymph nodes, or liver) occurs in a subset of PPGLs, ranging from 15% to 17% depending on the underlying pathogenic variants. Historically, pulmonary metastases present clinically as multiple small lesions; however, cases of PPGLs with innumerable small metastases (a miliary pattern) overwhelming lung parenchyma define a novel yet exceptionally challenging disease presentation. This pattern of pulmonary lesions upon treatment and/or cellular lysis may lead to both respiratory decompensation as well as prolific catecholamine release, incurring significant morbidity and mortality if not appropriately managed. Of the 2,649 PPGL patients enrolled in our protocol from January 1, 2000, to April 30, 2023, 500 had metastatic disease, 122 were children/adolescents, and 3 of the 122 children/adolescents had extensive pulmonary metastatic disease. All three adolescent patients with extensive pulmonary metastases had cluster 1 PPGLs and suffered hypoxemia (due to pulmonary metastases) leading to overactive hypoxia signaling and catecholamine-induced signs and symptoms [among them hypertension and/or tachyarrhythmia(s)]. Interventions including surgery, chemotherapy, and radiotherapy were pursued. Two patients achieved disease stability, while one patient succumbed to disease. Ultimately these divergent outcomes emphasize the importance of recognizing poor prognostic factors and aggressive disease early, to select appropriate treatments. Optimal management of these patients must consider complications of catecholamine excess and the profound influence of hypoxia. Herein, we describe three adolescent cases of extensive pulmonary metastatic PPGL and the unique clinical challenges faced in treating these tumors alongside relevant literature to provide guidance on appropriate interventions (ClinicalTrials.gov identifier: NCT00004847).

Current diabetes guidelines recommend people with gestational diabetes mellitus (PwGDM) use primarily blood glucose meters (BGM) for diabetes management. We evaluated glycemic trends and guideline-recommended glycemic targets achieved in PwGDM using a diabetes app with a family of Bluetooth® connected BGMs.
Anonymized glucose and app analytics data from 26,382 PwGDM were sourced from a server. Data from their first 7-days using the app with connected BGMs was compared to 7-days prior to a 10-week timepoint.
Percent fasting readings in range (RIR, < 5.3 mmol/L) improved by +20.3 percentage points in the overall population. Improved glucose RIR (3.5 to 7.8 mmol/L) (+8.3 percentage points), mean blood glucose (BG, –0.59 mmol/L), and fasting RIR (+33.2 percentage points) were observed in those with baseline mean BG ≥ 6.1 mmol/L. Improvements in mean BG of –0.32 to –2.36 mmol/L, and RIR of +3.0 to +38.3 percentage points correlated with higher baseline mean BG ≥ 6.1 to ≥ 7.8 mmol/L. Only 58.5% of PwGDM with baseline mean BG ≥ 6.1 mmol/L had > 80% RIR at baseline, which improved to 79.5% at 10 weeks. PwGDM averaged 17 app sessions and 90 minutes per week on the app.
PwGDM engaged with the diabetes app and connected BGM, facilitating attainment of glycemic targets, an especially important outcome for those with higher mean glucose at baseline.

Metabolic syndrome (MetS) is associated with chronic conditions, including type 2 diabetes mellitus (T2DM) and cardiovascular disorders. New markers are needed for the early detection and successful treatment of MetS, especially in patients with T2DM. The serum uric acid-to-creatinine ratio (UCR) and waist-to-height ratio (WHR) are novel markers in various chronic metabolic disorders. We aimed to compare WHR, UCR, and other metabolic and laboratory markers in T2DM patients with and without MetS.
Patients with T2DM who visited the outpatient clinics of our institution were enrolled in the study. Total diabetic subjects were 239 of which 180 were in MetS group while 59 were in without MetS group. Data from both study groups were compared.
The serum UCR in the MetS and control groups was 6.3 ± 2.1 and 5.8 ± 1.6, respectively (p = 0.04). The WHR in the MetS and control groups was 0.65 (0.47–0.87) and 0.62 (0.35–0.84), respectively (p < 0.001). Significant positive correlations were observed between UCR and triglycerides (r = 0.17, p = 0.009), waist circumference (r = 0.13, p = 0.046), hip circumference (r = 0.18, p = 0.006), BMI (r = 0.2, p = 0.002), and GFR (r = 0.4, p < 0.001). Similarly, significant positive correlations were noted between WHR and systolic blood pressure (r = 0.12, p = 0.049), weight (r = 0.5, p < 0.001), BMI (r = 0.7, p < 0.001), and UCR (r = 0.12, p = 0.047). In the ROC analysis, the sensitivity and specificity of WHR (when higher than 0.64) in detecting MetS were 72% and 54%, respectively (AUC: 0.69, p < 0.001, 95% CI: 0.61–0.77).
We propose that WHR and UCR could be valuable tools for the early detection of MetS in patients with T2DM. The ease and low cost of evaluating WHR and UCR make them practical markers for monitoring and diagnosing MetS.

Regenerative and curative strategies would be desirable for neurodegenerative and adrenal diseases, and multipotent adrenal stem cells are considered as promising biological tools for this purpose. Stem-like cells with the potential to proliferate and differentiate in vivo and in vitro were discovered in both cortex and medulla of the adrenal gland. Previously, it was demonstrated that nestin-positive progenitors in the cortex and medulla, play an important role under stress. In the present study, the cultivation of these cells was optimized and their growth in vitro was characterized.
Primary cells from the adrenal cortex and medulla from Nes-GFP mice were isolated and the in vitro culture conditions promoting the growth of stem and progenitor cells using different 3-dimensional (3D) spheroid culture models were optimized.
Both cortical and medullary cells could be cultured for at least one month under several different low-adherence conditions maintaining their viability and potential to differentiate. Medullary cells grew faster than cortical cells. Endothelin did not affect the cultures.
Adrenomedullary and adrenocortical nestin-positive progenitor cells can be cultured long-term in 3D cultures maintaining their proliferation and differentiation capabilities. Such multidimensional models can potentially be used for drug screening to develop personalized medicines or for transplantation to treat neurodegenerative disorders or adrenal diseases, such as adrenal insufficiency.

To evaluate changes in quality of life via the ageing male symptom scale (AMSS) and somatic, psychological, and sexual sub-scales following testosterone undecanoate (TU) or placebo (P) treatment in men with type 2 diabetes mellitus (T2DM) and adult-onset testosterone deficiency (TD) via a re-analysis of the BLAST (Burntwood, Lichfield, Atherstone, Sutton Coldfield, and Tamworth) randomised controlled trial (RCT).
Analysis of data from the BLAST RCT in men with T2DM and adult-onset TD was performed. Summation baseline and study-end AMSS data were available in 170 men (94: P; 76: TU) with subscale data available in 82 men. Rank-sum and sign-rank tests determined inter/intra-group differences, whilst linear/multiple regression models identified predictors of AMSS change.
AMSS improved significantly in P [–2 (median), p = 0.010] and TU [–6 (median), p < 0.0001)] arms, with greater improvement observed in men on TU (p = 0.014). No significant change was seen in either arm with baseline AMSS < 27 (asymptomatic). TU was significantly associated with AMSS improvement in all symptomatic AMSS categories. Improvement in the P arm was confined to men with baseline AMSS > 49. In the cohort with subscale AMSS data, TU was associated with improvements in somatic, psychological, and sexual subscales, whilst improvement was limited to the somatic subscale in the men on P. TU (reference: P) and higher baseline AMSS were significantly and independently associated with AMSS improvement. The improvement in summation AMSS associated with TU (reference: P) was only evident in men with mild depression and no anxiety (based on baseline Hospital Anxiety and Depression Scale data).
TU appeared associated with improved AMSS (summation and subscales) in men with T2DM and adult-onset TD demonstrating symptoms (AMSS ≥ 27) with this benefit mediated by levels of depression and anxiety (European Union Clinical Trials Register, EudraCT 2008-000931-16).

For the past 100 years, insulin supplementation has been the mainstay of treatment for type 1 diabetes (T1D), which is characterized by progressive autoimmune-mediated loss of insulin-producing β cells in the islets of Langerhans over the last decades, technological advances in glucose monitoring and therapeutics have greatly improved the care and management of these patients. However, morbidity, mortality, and quality of life remain challenges for patients with T1D. Islet transplantation has been successfully performed, but there are several limiting factors, such as the lack of cadaveric donors and the need for lifelong immunosuppressive therapy. Therefore, there is a great medical need for alternative therapeutic approaches. In the current review, the current knowledge on novel approaches for the treatment of T1D with a focus on the potential of using chimeric antigen receptor (CAR)-T cells and natural killer (NK) cells is summarized.
