There is accumulating evidence that the immune system can produce neuropeptides. In the light of these facts, we obtained direct evidences to prove that T lymphocytes also synthesize and secrete calcitonin gene-related peptide (CGRP), a neuropeptide localized within primary sensory nerves. By using CGRP specific RIA, CGRP-like immunoreactivity (LI) was(More)
Circadian oscillation and cell cycle progression are the two most essential rhythmic events present in almost all organisms. Circadian rhythms keep track of time and provide temporal regulation with a period of about 24 h. The cell cycle is optimized for growth and division, but not for time keeping. Circadian gated cell divisions are observed in nearly all(More)
Calcitonin gene-related peptide (CGRP) is a 37-amino acid neuropeptide, which is mainly present in primary sensory nerves. Although our previous study has shown that rat lymphocytes can synthesize beta-CGRP, there is no evidence demonstrating whether CGRP can be synthesized by human lymphocytes. In this study, the production of CGRP from human lymphocytes(More)
Our previous data have shown that rat lymphocytes can synthesize calcitonin gene-related peptide (CGRP), a neuropeptide. In this study the type, characteristics, and functional role of lymphocyte-derived CGRP were investigated. The results showed that treatment with Con A (4 microg/ml) and recombinant human IL-2 (rhIL-2; 750 U/ml) for 3-5 days induced CGRP(More)
Calcitonin gene-related peptide (CGRP), a neuropeptide contained in primary sensory neurons, has been demonstrated to be synthesized and released by rat lymphocytes in our previous studies. In this study, the release properties and molecular characteristics of CGRP such as immunoreactivity (CGRP-LI) from lymphocytes were compared with those from dorsal root(More)
