Evaluation of genetic control of the immune response to penicillin in man.
HLA typing of 46 patients with demonstrated penicillin allergy did not show significant correlation of hypersensitivity to the penicilloyl group with any HLA antigens. On the other hand, lymphocytes from penicillin-sensitive patients generated nonspecific cytotoxic cells (e.g., cytotoxic for P 815 mastocytoma mouse cells or chicken red blood cells) when cultured in vitro together with penicillin. Under similar conditions, only some lymphocyte populations from nonpenicillin-sensitive normal individuals showed cytotoxicity. Although family studies are required to demonstrate that differences in the generation of cytotoxic cells by penicillin in nonsensitive populations are due to genetic factors, it is obvious that attempts to achieve primary sensitization in vitro is the most rational approach to a study of Ir genes in man.
