title: Characterization of mononuclear cell infiltrates in psoriatic lesions.
abstract: The dermal mononuclear cell infiltrates of psoriatic lesions were characterized by receptors for sheep erythrocytes (T-lymphocytes), C3b receptors (macrophages and B-lymphocytes) and C3d receptors (B-lymphocytes), using hemadsorption to cryostat sections in a closed chamber. T-lymphocytes and macrophages were the predominant inflammatory cells. Very few B-lymphocytes were detected. These findings are discussed in relation to the possible pathogenetic signficance of cellular immunity in psoriasis.
