  • Title: Lymphocyte subpopulations in rheumatic heart disease.
    Author: Regelmann WE, Gray ED, Wannamaker LW, Lebien TW, Mansour M, el Kholy A, Abdin Z.
    Journal: J Rheumatol; 1987 Feb; 14(1):23-7. PubMed ID: 2952796.
    Abstract:
    Monoclonal antibodies and indirect immunofluorescence techniques were used to compare the distribution of lymphocyte subpopulations of tonsil and peripheral blood from patients with rheumatic heart disease and age and socioeconomically matched patients undergoing tonsillectomy for chronic recurrent tonsillitis, but who had no evidence of rheumatic fever or rheumatic heart disease. The proportions of B cells (BA-1+), total T cells (Lyt-3), inducer/helper T cells (T4+) and cytotoxic/suppressor T cells (T8) were determined. No significant differences were apparent between rheumatic heart disease and control groups in resting cells from tonsils or blood. Cells undergoing proliferation in response to streptococcal blastogen A were identified by similar techniques. These tonsillar preparations from patients with rheumatic heart disease generated a smaller proportion of T8+ cultured cells and a greater T4/T8 ratio of cultured cells in response to group A streptococcal blastogen A than did nonrheumatic subjects.
