VPAC-1 receptor expression on primary mouse macrophages was regulated by both stimulatory (LPS, IFN-γ) and suppressive (IL-10, TGF-β) signals, explaining how the VIP anti-inflammatory system adapts to inflammatory context.
Key findingVPAC-1 receptor on macrophages was upregulated by pro-inflammatory signals (LPS, IFN-γ) and downregulated by anti-inflammatory signals (IL-10, TGF-β)
What the researchers found
VPAC-1 receptor on macrophages was upregulated by pro-inflammatory signals (LPS, IFN-γ) and downregulated by anti-inflammatory signals (IL-10, TGF-β) — dynamic receptor regulation that adapts VIP anti-inflammatory sensitivity to the inflammatory microenvironment.
