Inhibition or blockage of TSP4 expression through TSP4-AON or antibody reversed or prevented the development of behavioral hypersensitivity
Study | Animals (species/types) | Procedures | Results |
---|---|---|---|
Kim et al. [41], 2012 | Male young adult Harlan Sprague-Dawley rats | TSP4 antibody 80 μg/rat, intrathecal, two weeks after L5/6 SNL | Both tactile allodynia and mechanic and thermal hyperalgesia reversedAll effects peaked at 6 h after TSP4 antibody injection |
TSP4 antibody, 80 μg/rat per day, intrathecal immediately before, for eight days, and after SNL | Pre-emptive TSP4 antibody treatment prevented allodynia onset | ||
TSP4-AON, 50 μg/rat per day, intrathecal, for four days after SNL | Tactile allodynia and thermal and mechanical hyperalgesia reversed time-dependently | ||
Zeng et al. [98], 2013 | Adult female Sprague-Dawley rats | TSP4-AON, 50 μg/rat per day, intrathecal, post-SCI for four days | The antiallodynic effect developed after the last injection and lasted more than two daysSCI-induced TSP4 expression was reduced in the DSC by 40% |
Li et al. [97], 2014 | Adult male Sprague-Dawley rats | TSP4-AON, 50 μg/10 μL per rat per day, intrathecal, for four consecutive days, starting at least three weeks post-CCI of the infraorbital nerve | After the last injection, the antiallodynic effect peaked at approximately one day and lasted over two days. Simultaneously, injury-induced TSP4 expression diminished in the C1/2 DSC |
Crosby et al. [30], 2015 | Adult male Holtzman rats | TSP4-AON, 75 μg/rat per day, intrathecal, for three days before FJD and seven days after FJD | Pre-emptive TSP4-AON treatment prevented the development of tactile allodynia and the increase in TSP4 expression in the C6/7 spinal cord following FJDFJD-induced excitatory synapse density is reduced in the superficial DH |
