Localized treatment with recombinant human interleukin-2 (rIL-2) +/- recombinant murine interferon-gamma (rIFN-gamma) results in regression of early B16 melanomas in normal C57BL/6 (B6) mice, but not in syngeneic beige mice, which have defective natural killer (NK) cells. Injection of antibodies to asialo GM1 (a-AGM1) or Thy1 abolishes the tymoricidal effects of rIL-1 +/- rIFN-gamma. Thus, cells activated by these cytokines must be either NK-like cells that are AGM1+ Thy1+, or NK-like cells (AGM1+) cooperating with T lymphocytes (Thy1+), since either antibody (a-AGM1 or a-Thy1) independently abrogates the in vivo antitumor effect.
用重组人白细胞介素-2(rIL-2)+/-重组鼠干扰素-γ(rIFN-γ)进行局部治疗可使正常C57BL/6(B6)小鼠的早期B16黑色素瘤消退,但同基因的米色小鼠则不然,这些米色小鼠的自然杀伤(NK)细胞存在缺陷。注射抗唾液酸化GM1(a-AGM1)或Thy1抗体可消除rIL-1+/-rIFN-γ的杀肿瘤作用。因此,被这些细胞因子激活的细胞必定是a-AGM1+Thy1+的NK样细胞,或者是与T淋巴细胞(Thy1+)协同作用的NK样细胞(a-AGM1+),因为任何一种抗体(a-AGM1或a-Thy1)均可独立消除体内抗肿瘤作用。
