TNFRSF1B and peripheral nerve injury: The study of the different temporal profiles of TNFR1 vs. TNFR2 activation during WD disclosed the long-lasting upregulation of TNFR2 up to 28 days after peripheral nerve injury when nerve regeneration occurred, in contrast with the highest activation of TNFR1 during the first days after CCI when maximal is the hyperalgesic response [69].
