Abstract:
:Calcitonin gene-related peptide has been identified by immunocytochemistry within the thymus of fetal through aged adult mice. Calcitonin gene-related peptide positive nerves are observed from embryonic day 17 throughout the lifespan of the mouse. A sparse cell population positive for CGRP is first observed during the late embryonic period at the corticomedullary boundary and the medulla, and it becomes more densely distributed in this region in the adult. In the thymus of the aged mouse the number of CGRP-positive cells diminishes. Pharmacologic studies demonstrated that fresh thymocytes display a receptor Kd for CGRP of 1.17 +/- 0.06 x 10(-10)M and a Bmax of 12.7 +/- 4.7 fmol/mg protein. Functional studies indicate that CGRP is a potent inhibitor of mitogen and antigen-stimulated proliferation of T cells and that it inhibits IL-2 production in cloned splenic T cells. Recent studies suggest that endogenous CGRP may serve as a natural inhibitor of inappropriate induction of mature, antigen-sensitive cells in the thymus as well as play a role in thymocyte education. These findings are discussed in terms of the distribution of CGRP cells and nerve terminals within the thymus and their relationship to positive and negative selection of the T-cell repertoire.
