However, the endogenous activation of neuronal TLR4 during neuroinflammation, in
absence of the participation of glial TLR4, remains elusive. Here, we identified lysozyme as
an endogenous activator of neuronal TLR4 signaling during nerve injury. Upon nerve injury,
enhanced expression of lysozyme promoted neuronal hyperexcitability and neuropathic
pain. Injections of lysozyme in healthy rats increased their mechanical and thermal pain …
