Antagonist interleukin-1 receptora (IL-1RA) je protein koji je kod ljudi kodiran IL1RN genom.^[1]^[2]

IL-1RA antagonist se ranije zvao IL-1 inhibitor. Njega su nezavisno otkrile dve laboratorije 1984 godine.^[3] IL-1RA, se vezuje za interleukin-1 receptor (IL-1R) na površini ćelija. Za IL-1R se isto tako vezuje interleukin 1 (IL-1). IL-1RA sprečava IL-1 da pošalje signal.

Funkcija уреди

IL-1RA je član interleukin 1 citokin familije. Ovaj protein inhibira aktivnosti interleukina 1, alfa (IL1A) i interleukina 1, beta (IL1B), i modulira niz interleukin 1 zavisnih imunskih i inflamatornih odgovora. Ovaj gene i pet drugih blisko srodnih citokin gena formiraju genski klaster koji obuhvata približno 400 kb na hromozomu 2. Četiri alternativno splajsovane transkriptne varijante koje kodiraju jedinstvene izoforme su bile utvrđene.^[4]

Klinički značaj уреди

Za polimorfizam ovog gena se smatra da je vezan za povećani rizik osteoporoznih fraktura^[5] i gastričnog karcinoma.^[6]

Mutacije u IL1RN genu rezultuju u retkoj bolesti koja se zove nedostatak antagonista interleukin-1 receptora (DIRA).^[7] Varijante IL1RN gena su takođe asocirane sa rizikom od shizofrenije.^[8]^[9] Povišeni IL1RN nivoi su nađeni u serumu obolelih od shizofrenije.^[10]

Interleukin 1 receptor antagonist je korišćen u tretmanu reumatoidnog artritisa, autoimune bolesti u kojoj IL-1 igra ključnu ulogu. On se komercijalno proizvodi kao anakinra, što je ljudska rekombinantna forma L-1RA. U pogledu proteinske sličnosti, IL-1β srodniji sa IL-1RA nego IL- 1α.^[3]
