ABSTRACT
Analysis of T-lymphocytes and their subsets in the blood and bronchoalveolar lavage fluids from 12 patients with active pulmonary tuberculosis, 12 patients with bronchogenic carcinoma and 11 healthy volunteers was aimed at identifying their immunologic functions and interrelationships. In patients with active pulmonary tuberculosis, there was a significant increased in the percentage of T-cells bearing IL-2 receptor both in the blood and bronchoalveolar lavage fluids, whereas patients with bronchogenic carcinoma exhibited an increase in the suppressor T-cells and T-cells bearing IL-2 receptor in the blood only. The presence of T-cells bearing IL-2 receptor is generally accepted to be the hallmark of recently active specific antigen activation of the helper T-lymphocytes together with monokine IL-1 stimulation. Suppressor T-cells, on the other hand, play a role in the immunopathogenesis of lung cancers and lung metastasis.
