title: [Lymphocyte membrane receptors mediating recognition of antigens (author's transl)].
abstract: The present article summarizes briefly our knowledge of antigen-specific B- and T-lymphocyte receptors. Antigen-specific receptors on mammalian B-lymphocytes are mainly monomeric IgM and IgD consisting of conventional immunoglobulin heavy and light chains. The nature of the T-lymphocyte receptors which can specifically recognize antigens is not yet fully defined but it seems that conventional light chains do not participate in the build up of this receptor. However, T-lymphocytes express two polypeptide chains which bear variable domains sharing idiotypic determinants with the corresponding B-lymphocytes. These Tau chains can bind the corresponding antigen.
