Neuropeptid S (NPS) je neuropeptid nađen u mozgu ljudi i sisara. Njega uglavnom proizvode neuroni amigdale, mada NPS-responsivni neuroni pružaju projekcije u mnoge druge oblasti mozga.[1][2][3] NPS se specifično vezuje za NPSR G protein-spregnuti receptor.[4][5] Ispitivanja na životinjama su pokazala da NPS umanjuje anksioznost i apetit, indukuje budnost i hiperaktivnost, što obuhvata hiper-seksualnost, i ima znatnu ulogu u iskorenjivanju uslovljenog straha.[6][7][8][9][10][11][12] Takođe je bilo pokazano da znatno uvećava dopaminsku aktivnost u mezolimbnom putu.[12]

Ne-peptidni antagonist NPS receptora, SHA-68, blokira NPS dejstvo kod životinja i proizvodi anksiogene efekte.[13] Nekoliko peptidnih agonista u antagonista izvedenih iz NPS je takođe poznato.[14][15][16][17][18]
