Posttraumatic autoimmune reaction in peripheral nerve: effect of a single injury.
This study was conducted to show that local autoimmune reactions could be observed in rat sciatic nerve after a single injury. Furthermore, we attempted to correlate the intensity of the immunological reaction with the severity of nerve damage, with the type of surgical treatment and with the degree of functional recovery. Through the use of direct immunofluorescence techniques, we found that the severity of the initial damage was associated with the intensity of the local immunological response assessed 2.5 months after surgery. There was an association between type of surgical treatment and intensity of the autoimmune reaction. A correlation between autoimmune reaction and degree of long-term functional impairment was not immediately clear. The probable factors that underlie these results are discussed.
