[Phenotypic and functional analysis of blood lymphocytes and pathological focus in patients with pulmonary tuberculosis].

A subpopulation study of lymphocytes concentrating in cavernous, lymph node tissues and blood from patients with fibrous-cavernous tuberculosis of the lungs showed that in spite of high CD3+ and CD4+ cell levels in the cavern, the response of these cells to mitogens may be weaker than blood lymphocyte response. IL-2 production by cavern lymphocytes varied and was unrelated to proliferative response of these cells to M. tuberculosis antigens.
