Kortikotropin-oslobađajući hormon (CRH, originalno nazvan kortikotropin-oslobađajući faktor, CRF, takođe poznat kao kortikoliberin), je polipeptidni hormon i neurotransmiter koji učestvuje u odgovoru organizma na stres. On pripada familiji kortikotropin-oslobađajućih faktora.

Njegova glavna funkcija je stimulacija hipofizne sinteze adrenokortikotropnog hormona.

Kortikotropin-oslobađajuči hormon je 41-aminokiselina dug peptid izveden iz 191-aminokiselinskog preprohormona. CRH izlučuje paraventrikularni nukleus (PVN) hipotalamusa u odgovoru na stres. Primetno umanjenje CRH koncentracije je bilo primećeno kod obolelih od Alchajmerove bolesti. Osim što se proizvodi u hipotalamusu, CRH je takođe sintetisan u perifernim tkivima, poput T limfocita, i visoko je izražen u posteljici. U posteljici je CRH služi kao indikator koji određuje dužinu gestacije i vreme porođaja. Brzo povišenje CRH nivoa u cirkulaciji se javlja na početku porođaja.^[1]

Struktura

CRH su otkrili Vale et al. kod ovaca 1981.^[2] Njegova sekvenca je:

SQEPPISLDLTFHLLREVLEMTKADQLAQQAHSNRKLLDIA

Peptidi pacova i čoveka su identični i razlikuju se od ovčije sekvence za samo 7 aminokiselina.^[3]

Interakcije

Za kortikotropin-oslobađajući hormon je pokazano da interaguje sa kortikotropin-oslobađajućim hormonskim receptorom 1.^[4]^[5]
