Objective To examine the effect of neuropeptide Y （NPY） on TGF-β1 production in RAW264.7 macrophages. Methods Enzyme linked immunosorbent assay （ELISA） was used to detect TGF-β1 production. Cell counting kit 8 （CCK-8） was used to assay the viability of RAW264.7 cells. Western blot was used to detect the phosphorylation of PI3K p85. Results NPY treatment could promote TGF-β1 production and rapid phosphorylation of PI3K p85 in RAW264.7 cells via Y1 receptor. The elevated TGF-β 1 production induced by NPY could be abolished by wortrnannin pretreatment. Conclusion NPY may elicit TGF-β production in RAW264.7 cells via Y1 receptor, and the activated PI3K pathway may account for this effect.
