Lysis of human melanoma cells by autologous cytolytic T cell clones. Identification of human histocompatibility leukocyte antigen A2 as a restriction…
1989
From the peripheral blood of the melanoma patient (AV), we derived cytolytic T lymphocyte (CTL) clones that lysed the autologous tumor line SK-MEL-29, but not autologous EBV-B cells, K562, and other tumor targets. By immunoselection experiments it was shown that the CTL clones recognized at least three different antigens on the autologous tumor cells. We demonstrate here that these melanoma antigens are presented to the CTL in association with HLA-A2. First, HLA-A2-reactive pregnancy sera as well as an mAb against HLA-A2 inhibited the CTL lysis. Second, immunoselected melanoma subclones that were resistant to lysis by CTL clones against the three antigens described were found to lack expres…
In Vivo Protective Effect of Tumour Necrosis Factor Against Experimental Infection with Herpes Simplex Virus Type 1
1991
C57BL/6 mice, which differ genetically from other strains by their resistance to herpes simplex virus type 1 (HSV-1) infection, were inoculated intraperitoneally with different doses of tumour necrosis factor alpha (TNF-alpha). Mice pretreated with 100 ng, or even 10 ng, of TNF-alpha showed prolonged survival compared to control mice that were infected with 10(7) p.f.u. of HSV-1. Significant protection was observed in mice injected 4 or 8 h prior to or after HSV-1 inoculation, respectively. Protection was also observed when mice which differed at their H-2 locus were treated with TNF-alpha after infection with HSV-1. Interferon could not be detected in the sera of mice at different time poi…
