The effect of cytotoxic monoclonal antibodies against T lymphocyte subpopulations on skin allograft survival in mice was compared. Antibodies against cytotoxic lymphocytes (anti-Lyt-2.2) suppressed the allotransplantation reaction more effectively than antibodies against helper/inducer T lymphocytes (monoab anti-Lyt-1.2 and GK1.5). The suppressive effect of(More)
Transplantation tolerance was induced in A.TL mice to donors having disparity in the Ia antigens and identity at the H-2K, H-2D and non-H-2 antigens. After neonatal injection of 12 X 10(6) semiallogeneic lymphoid cells, permanent survival of A.TH skin allografts was observed in more than 90% of the recipients. Adoptive transfer of 50 X 10(6) lymphoid cells(More)
Specific immunity to Rous virus-induced sarcoma (RSL) was investigated by the tube leukocyte adherence inhibition (LAI) assay in rats immunized with Bacillus Calmette-Guérin (BCG). Peritoneal cells from Lewis rats immunized s.c. with BCG gave positive reactions in the tube LAI assay with the antigen prepared from RSL in Lewis rats. Lymph node cells from(More)
Antigen-induced inhibition of leukocyte adherence is a suitable method providing information on immunological response of the tumor bearers. Leukocytes from patients' blood were tested by an in vitro method to detect cell-mediated antitumor immunity. Positive reactions of leukocytes to the specific antigen were found in carcinoma of the uterine cervix,(More)
