Tumorski faktor nekroze (TNF , kaheksin ili kahektin , zvani i tumorski faktor nekroze alfa ili TNF-α ) citokinski mali protein koji koristi imunski sistem za ćelijsku signalizaciju . Ako makrofazi (određena bijela krvna zrnca ) otkriju infekciju, oslobađaju TNF, kako bi upozorili druge ćelije imunskog sistema kao dio upalnog odgovora . TNF je član superporodica TNF , koja se sastoji od različitih transmembranskih proteina s homolognim domenom TNF.
TNF signalizacija javlja se putem dva receptora: TNFR1 i TNFR2.[ 5] [ 6] TNFR1 je konstitutivno eksprimiran na većini tipova ćelija, dok je TNFR2 ograničen prvenstveno na endotelne , epitelne i podskupine imunskih ćelija.[ 5] [ 6] Signalizacija TNF1 ima tendenciju da bude proupalna i apoptotska , dok je signalizacija TNFR2 protivupalna i podstiče ćelijsku proliferaciju .[ 5] [ 6] Suzbijanje signalizacije TNFR1 bilo je važno za liječenje autoimunske bolesti ,[ 7] dok signalizacija TNFR2 podstiče zacjeljivanje rana .[ 6]
TNF-α postoji kao transmembranski oblik (mTNF-α) i kao topljivi oblik (sTNF-α). sTNF-α je rezultat enzimskog cijepanja mTNF-α.[ 8] mTNF-α se uglavnom nalazi na monocitima/makrofazima, gdje stupa u interakciju s tkivnim receptorima, dodirom ćelija na ćeliju.[ 8] sTNF-α se selektivno veže za TNFR1, dok se mTNF-α veže i za TNFR1 i za TNFR2.[ 9] Vezivanje TNF-α za TNFR1 je ireverzibilno, dok je vezivanje za TNFR2 reverzibilno.[ 10]
Primarna uloga TNF-a je u regulaciji imunskih ćelija . TNF, kao endogeni pirogen, može izazvati groznicu , apoptotsku ćelijsku smrt , kaheksiju , upalu i inhibirati tumorigenezu , replikaciju virusa , a i reagiraju na sepsu putem ćelijskih IL-1 i IL-6 . Disregulacija proizvodnje TNF-a uključena je u različite ljudske bolesti , uključujući Alzheimerovu ,[ 11] kancer ,[ 12] glavnu depresiju ,[ 13] psorijazu [ 14] i upalnu bolest crijeva (IBD).[ 15] Iako kontroverzne, neke studije povezuju depresiju i IBD s povećanim nivoom TNF -a.[ 16] [ 17]
Pod imenom tasonermin , TNF se koristi kao imunostimulacijski lijek u liječenju određenih karcinoma. Lijekovi koji se suprotstavljaju djelovanju TNF-a koriste se u liječenju različitih upalnih bolesti, naprimjer reumatoidnog artritisa .
Određeni karcinomi mogu uzrokovati hiperprodukciju TNF-a. TNFsu paralele paratireoidnih hormona i u izazivanju sekundarne hiperkalcemije i u raku s kojim je povezana prekomerna proizvodnja.
