Abstract: | Activation of naturally sensitized human T lymphocytes to Candida allergen was studied using three HLA-D and DR heterozygote Japanese cells (Dw1.DR1/DYT.DR4, Dw12.DR2/DYT.DR4, DYT.DR4/DEn.DR blank) and four HLA-D and DR homozygote cells (Dw1.DR1, Dw12.DR2, DYT.DR4, DEn.DR blank). In vitro activation of T lymphocytes to Candida allergen was found to require the presence of autologous or allogeneic compatible HLA-Dw1.DR1 and Dw12.DR2 macrophages. |
