Abstract
We demonstrated that up-regulation of microglial TREM2 and amplification of both microglial M1 and M2 response was along with the presence of diabetes-related mechanical allodynia and thermal hypersensitivity. Moreover, we found that overexpression of TREM2 in microglia aggravated the symptom of PDN, amplified microglia M1 response, and suppressed microglia M2 polarization in the lumbar spinal cord of diabetic mice. However, inhibition of TREM2 with anti-TREM2 neutralizing antibodies attenuated mechanical allodynia and thermal hyperalgesia in diabetic mice. Besides, we identified Galectin-3 (GLT-3) as the potential ligand of the TREM2 receptor in facilitating the progression of PDN.
