Exposure of endothelial cells (ECs) to the neuropeptide calcitonin gene-related peptide (CGRP) endows them with ability, as bystanders, bias outcome LC antigen (Ag) presentation T toward Th17 pole and our previous work indicates that EC IL-6 production mediates most this effect. Preliminary experiments suggested could enhance expression by LCs. We have further examined effect released CGRP-expo...
