It is well documented that neuropeptide Y (NPY) exerts a wide range of biological functions through at least five NPY Y receptor subtypes (Y1-Y5), but its immunological effects only recently came into focus. Using NPY family pepticles and NPY-related receptor-specific peptides as well as Y1 and Y2 receptor antagonists, we have tested which NPY Y receptors are involved in NPY-induced modulation of rat peritoneal macrophage function in vitro. NPY and PYY increased oxidative burst in phorbol myristate acetate (PMA)-stimulated macrophages involving activation of protein kinase C (PKC), and decreased it in zymosan-stimulated cells resembling inhibition of signaling pathways subsequent to binding of zymosan particles for the iC3b fragment receptor on macrophages. The combined treatment with NPY and NPY Y receptor antagonists revealed that NPY-induced potentiation of oxidative burst in PMA-stimulated cells is mediated through Y1 and Y2 receptors, while NPY-induced suppression in zymosan-stimu...lated cells is mediated through Y2 receptors only. NPY-related peptides differently modulated macrophage function, confirming involvement of NPY Y2 receptor in both potentiation and suppression of oxidative burst in these cells. Additionally, it was shown that NPY Y5 receptor mediated suppression of oxidative burst in PMA- and zymosan-stimulated macrophages. Taken together, the present data reveal an NPY Y1 and Y2/Y5 receptor interaction in NPY-induced modulation of macrophage functions related to inflammation. (C) 2004 Elsevier B.V. All rights reserved.
