In vitro

PACAP 1-38 has potent, efficacious, and sustained stimulatory effects on sympathetic neuronal NPY and catecholamine production. It is a pleiotropic neuropeptide, exhibiting a variety of biologic actions, including activities as a neurotransmitter, neuromodulator, neurotrophic factor, as well as an immunomodulator, in immune cells through its effect on MAPK signaling and modulation of activation of NFκB. This compound dramatically prevents injury of cultured renal proximal tubule cells caused by myeloma light chains through suppression of proinflammatory cytokines production, by inhibiting p38 MAPK and translocation of NFκB via both PAC1 and VPAC1 receptors. It inhibits myeloma cell growth directly and may also indirectly by suppressing production of the growth factor, IL-6, from bone marrow stromal cells, that is stimulated by adhesion of myeloma cells. This neuropeptide suppressed release of both IL-6 and TNFα dose dependently.
In vivo

PACAP38 is capable of inhibiting light chain-induced cytokine expression with a great potency and prevented the resulting cell damage in vivo. However, this compound is also considered as an autoregulatory factor for certain tumors, stimulating their growth in an autocrine fashion.
