Abstract

An assay based on the early stimulation of protein synthesis in lymphocytes has been used as an in vitro measure of cellular immune competence. 3H-labelled leucine incorporation into human peripheral lymphocytes (PBL) stimulated by the mitogens phytohaemagglutinin (PHA), wax bean agglutinin (WBA) and Concanavalin A (Con A) was measured after one day in culture. This assay offers a technical advantage over the analogous 3H-labelled thymidine incorporation assay, because of the short incubation time required and the absence of homologous serum in the assay system. Newborn infants and patients with Down's syndrome as a group had normal responses, whereas those suffering from recurrent infections demonstrated normal or hyper-reactive responses. Patients with lymphoproliferative disorders, ataxia telangiectasia, and some patients under steroid therapy had diminished immune proliferative reactions. These results are in agreement with most previously reported studies using other assay systems.
