title: [Expression of HLA-DP antigens on normal and leukemic blood cells].
abstract: HLA-DP allodeterminant elicit weak cellular and humoral immune responses. This study was undertaken to find out if the low immunogenicity of HLA-DP could be accounted for by a low level of expression on peripheral blood mononuclear cells. Double staining experiments and flow cytometry were performed in 28 healthy individuals, HLA-DP was found to be as expressed as DR and DQ on B lymphocytes. Furthermore, a DP+/DR- lymphocyte sub-population was identified and characterized as freshly activated T lymphocytes.
