The Functional Role Of Peripheral Nerves In Ige-Mediated Inflammation, Gary Wright Miller

Biological Sciences Theses & Dissertations

IgE-mediated inflammation was measured in mouse footpads with and without sciatic innervation. Mice were passively sensitized with IgE anti-dinitrophenol, a monoclonal antibody. Antigen-induced swelling was reduced by 26% by sciatic nerve transection. Whether transection occurred 10 days prior or immediately prior to antigen challenge did not affect the swelling response. The full inflammatory response was restored by antidromic stimulation of the distal portion of the cut nerve, but only in the freshly cut nerve. Antigen-induced swelling was unaffected by rhizotomy or spinal nerve transection. Pre-treatment with capsaicin reduced the swelling to a level similar to sciatic nerve transection. Treatment with …
