title: [Subpopulations of T lymphocytes in bronchoalveolar lavage (BAL) fluid of different interstitial lung diseases].
abstract: Immunocytochemical examinations using the PAP method with monoclonal antibodies against lymphocytes T (CD3, CD4, CD8) were carried out in 31 BAL's from patients with different interstitial lung diseases. A distinct increase of the CD4 (T "helper"): CD8 (T "suppressor") ratio was found in patients with sarcoidosis and in a patient with pigeon breeder's disease. A profound decrease of the CD4/CD8 ratio was found in HIV positive patients. The authors also discussed the methodological problems of correct typing of T cells in BAL.
