Abstract

Two different BALB/c anti-CBA (H-2k)monoclonal antibodies that bind to Kk and Dk antigens blocked Tc cell-mediated lysis of L929 (Kk, Dk) target cells, but with quite different specificity. One antibody (30R3) powerfully blocked Kk-specific lysis mediated by alloreactive or Kk-restricted Tc cells immune to ectromelia, Sendai, or influenza viruses. The other antibody (27R9) blocked these anti-Kk Tc cells much less than 30R3, but in contrast, 27R9 blocked anti-Dk lysis much more than 30R3. Most importantly, 27R9 strongly blocked Dk-restricted anti-influenza Tc cells, but did not significantly block Dk-restricted anti-Bebaru (BEB) lysis. This result indicated that different H-2 determinants coded in the D end of H-2k were recognized by influenza-and BEB-immune Tc cells. These determinants may be carried on two different molecules coded by the H-2D and H-2L loci, but other possibilities are not yet excluded.

摘要

两种不同的BALB/c抗CBA(H-2k)单克隆抗体,它们与Kk和Dk抗原结合,可阻断Tc细胞介导的L929(Kk,Dk)靶细胞裂解,但特异性差异很大。一种抗体(30R3)能有效阻断由同种反应性或对痘苗病毒、仙台病毒或流感病毒免疫的Kk限制性Tc细胞介导的Kk特异性裂解。另一种抗体(27R9)对这些抗Kk Tc细胞的阻断作用远小于30R3,但相比之下,27R9对抗Dk裂解的阻断作用远大于30R3。最重要的是,27R9强烈阻断Dk限制性抗流感Tc细胞,但对Dk限制性抗贝巴鲁(BEB)裂解无明显阻断作用。这一结果表明,流感免疫和BEB免疫的Tc细胞识别H-2k的D端编码的不同H-2决定簇。这些决定簇可能由H-2D和H-2L基因座编码的两种不同分子携带,但其他可能性尚未排除。
