Reference infokutije

Leukotrien E4 je cisteinilni leukotrien koji učestvuje u inflamaciji. Poznato je da ga proizvodi nekoliko tipova belih krvnih zrnaca, uključujući eozinofili, mastociti, tkivo makrofaga, i bazofili, i nedavno je utvrđeno da ga proizvode trombociti pričvšćeni za neutrofile.^[4] On se formira putem sekvencijalne konverzije od LTC4 do LTD4 i zatim do LTE4, što je krajnji i najstabilniji cisteinilni leukotrien.^[5] U poređenju sa kratkim poluživotima LTC4 i LTD4, LTE4 je relativno stabilan i akumulira se u kondenzatu daha, plazmi, i u urinu, što ga čini dominatnim cisteinil leukotrienom u biološkim fluidima.^[6] Merenja LTE4, posebno u urinu, se često vrše u kliničkim ispitivanjima.

Povišena produkcija i ekskrecija LTE4 je vezana za nekoliko respiratornih bolesti, i urinarni nivoi LTE4 su povišeni tokom ozbiljnih napada astme, a posebno su visoki kod ljudi sa aspirinom indukovanom astmom.^[7]
