Reduced inflammatory response and accelerated functional recovery following sciatic nerve crush lesion in CXCR3-deficient mice.

Despite the regenerative capacity of the peripheral nerve system (PNS), functional recovery after mechanical nerve trauma is often incomplete, resulting in motor, sensory, and autonomic deficits. The elucidation of key molecules involved in trauma-induced Wallerian degeneration and the ensuing regeneration processes is a prerequisite for the development of disease modifying drugs. The chemokine (C-X-C motif) receptor 3 (CXCR3) has been implicated in the recruitment of macrophages, the major immune cell population during the process of Wallerian degeneration.
