Immunogenetic analysis of delayed hypersensitivity to tuberculin in mice by the method of local adoptive transfer

: It has been demonstrated that a specific phase of DTH reaction to tuberculin is carried out (and in adoptive transfer-transferred) by T-lymphocytes with Lyt-1+, Lyt-2-, L3T4+ phenotype by a method of local adoptive transfer of this reaction from BCG-immunized mice to the pads of intact recipients. From genetic viewpoint, the above reaction is limited by 1-A beta, 1-A alpha genes. In a syngeneic apposition, monoclonal antibodies anti-1-A kappa beta (without complement) were blocking the reaction transfer to CBA mice A beta chain affected mutation bm12 failed to limit the reaction transfer in apposition B6----B6.C-H-2bm12.
