  • Title: T lymphocyte subpopulations defined by two sets of monoclonal antibodies in chronic active hepatitis and systemic lupus erythematosus.
    Author: Frazer IH, Mackay IR.
    Journal: Clin Exp Immunol; 1982 Oct; 50(1):107-14. PubMed ID: 6216997.
    Abstract:
    Lymphocyte subpopulations were enumerated in human peripheral blood using murine monoclonal antibodies with specificity for all peripheral blood T lymphocytes (OKT3, alpha-Leu 1) and for the helper subset (OKT4, alpha Leu 3a) and suppressor/cytotoxic subset (OKT8, alpha Leu 2a). Patients with chronic active hepatitis (CAH) (23) or systemic lupus erythematosus (SLE) (10), compared with healthy subjects (20), had a lower mean T lymphocyte count. Patients with CAH had normal numbers of suppressor/cytotoxic (TSC) cells, but fewer helper (TH) cells than healthy subjects (0 . 96 +/- 0 . 11 X 10(9)/1 versus 1 . 45 +/- 0 . 15 X 10(9)/1), and those with SLE also had fewer TH cells (0 . 93 +/- 0 . 11 X 10(9)/1). Patients with CAH receiving azathioprine (n = 8) had significantly fewer TSC cells, and a higher TH/TSC ratio (2 . 69 +/- 0 . 35) than those (n = 15) not on this therapy (1 . 85 +/- 0 . 15). When patients taking azathioprine were excluded, no correlation was found between disease activity and the TH/TSC ratio for either disease.
