克隆號(hào)14G2a單克隆抗體與人神經(jīng)節(jié)苷脂GD2反應(yīng),后者是一種含有唾液酸的糖脂,參與調(diào)節(jié)細(xì)胞與細(xì)胞外基質(zhì)的附著。神經(jīng)節(jié)苷脂GD2在神經(jīng)外胚層起源的腫瘤上表達(dá),包括人神經(jīng)母細(xì)胞瘤和黑色素瘤。GD2的腫瘤特異性表達(dá)使其成為用單克隆抗體或人工T細(xì)胞受體進(jìn)行免疫治療的合適靶標(biāo)。克隆號(hào)14G2a是選自親本產(chǎn)生IgG3的雜交瘤14.18的同種型開關(guān)變體,并且具有與親本抗體相同的反應(yīng)性。
