Neuropeptide AF (cattle) 

Neuropeptide AF (cattle), an amidated octadecapeptide, is RFamide neuropeptide. Neuropeptide AF (cattle) acts as a ligand of Mas-related gene receptor A4 (MrgprA4) (Mas-related G-protein-coupled Receptor (MRGPR)) (EC₅₀ of ~60 nM) and MrgprC11 (EC₅₀ of ~300 nM). Neuropeptide AF (cattle) also activate to the G protein-coupled receptors NPFF1 (Neuropeptide Y Receptor) (EC₅₀ of ~25-325 nM) and NPFF2 (EC₅₀ of ~1-5 nM). Neuropeptide AF (cattle) shows anti-opiate and related pain modulation effects^[1][2].

Neuropeptide AF (NPAF) (50, 100, 150, 300, and 600 nM) induces a piecemeal degranulation in bone marrow-derived mucosal mast cells (BMMCs). Neuropeptide AF can be considered as a novel modulator of BMMC activity in the neuro-immune communication in the gastrointestinal tract^[1].

Neuropeptide AF (cattle) (0.25 μg/2 μL; i.c.v.; 30 min prior to the tests) decreases the immobility time and increases the climbing and swimming times in modified mouse forced swimming test (mFST)^[2].
