Effect of TSPO expression on glioma progression

CharacteristicLow TSPO expression
(grades I–II)
High TSPO expression
(grades III–IV)
Reference
Cell proliferationLow proliferation rates, slower tumor growth.High proliferation rates and rapid tumor growth.[51]
ApoptosisIncreased apoptosis, less aggressive behavior.Reduced apoptosis and enhanced tumor survival.[68]
Invasion potentialLow invasiveness and well-defined tumor margins.Higher invasive capabilities and infiltrative tumor spread.[69]
Inflammation responseMild inflammatory response, less immune evasion.Strong pro-inflammatory environment, immune system suppression.[70]
Chemo-resistanceMore susceptible to therapy.Increased drug resistance and poor prognosis.[68]
