Struktura

uredi

Trodimenzijska kristalna struktura ovog hemokina određena je pod tri različita uslova do rezolucije do 1,92Å.[8] Pristupni kodovi Proteinske banke podataka za strukture CXCL10 su 1lv9, 1o7y i 1o80.

Funkcija

uredi

CXCL10 se izlučuje u nekoliko tipova ćelija, kao odgovor na IFN-γ. Ovi tipovi ćelija uključuju monocite, endotelne ćelije i fibroblaste.[5] Pripisuje mu se nekoliko uloga, kao što je hemoatrakcija za monocite / makrofage, T-ćelije, NK-ćelije i dendritske ćelije, promocija adhezije T-ćelija na endotelne ćelije, antitumorske aktivnosti i inhibicije formiranja kolonija koštane srži i angiogeneze.[9][10] Ovaj hemokin izaziva svoje efekte vezivanjem za hemokinske receprtore CXCR3 na površini ćelije.[11]

Biomarkeri

uredi

CXCL9, CXCL10 i CXCL11 su se pokazali kao valjani biomarkeri za razvoj srčane insuficijencije i disfunkcije lijeve komore, što ukazuje na potcrtavajući patofiziološki odnos između nivoa ovih hemokina i razvoja nepovoljnog remodeliranja srca.[12] [13]

Klinički značaj

uredi

Osnovni nivoi CXCL10 u plazmi prije tretmana su povišeni kod pacijenata hronično inficiranih virusom hepatitisa C (HCV) genotipova 1 ili 4 koji ne postižu trajni virusni odgovor (SVR) nakon završetka antivirusne terapije.[14][15] CXCL10 u plazmi sispoljava se u svojoj unutarjetrenoj iRNK, a oboje upečatljivo predviđaju prve dane eliminacije HCV RNK („opadanje prve faze“) tokom terapije interferonom/ribavirinom za sve HCV genotipove.[16] Ovo se također odnosi na pacijente koinficirane HIV-om, gdje nivoi IP-10 prije tretmana ispod 150 pg/mL predviđaju povoljan odgovor i stoga mogu biti korisni u ohrabrivanju ovih inače teško liječivih pacijenata da započnu terapiju.[17] Patogen Leishmania major ima proteazu, GP63, koja cijepa CXCL10, implicirajući CXCL10 u odbrambene mehanizme domaćina određenih unutarćelijskih patogena, poput Leishmania.[18]
