Abstract
T lymphocytes from 21 untreated patients with acute brucellosis were tested for their proliferative response to polyclonal mitogens. The purified T lymphocytes from these patients showed a defective proliferative response to plant lectins and anti CD3 monoclonal antibodies with respect to the response observed in T lymphocytes from 21 healthy controls (p0.05), and significantly higher than that found before treatment (p<0.05). It was concluded that T lymphocytes from acute brucellosis patients have a defective proliferative response to membrane mitogenic signals, which disappears when the patients are cured after antibiotic treatment. T-Lymphozyten von 21 unbehandelten Patienten mit akuter Bruzellose wurden auf ihre Proliferations-antwort auf polyklonale Mitogene untersucht. Auf Pflanzenlektine und anti-CD3-monoklonale Antikörper reagierten die gereinigten T-Lymphozyten dieser Patienten mit einer im Vergleich zu T-Lymphozyten von 21 gesunden Kontrollpersonen verminderten Proliferations-Antwort (p0,05) an; sie war gegenüber der Phase vor Therapie signifikant gesteigert (p<0,05). Aus diesen Befunden ist auf einen Defekt in der Proliferationsantwort der T-Lymphozyten auf mitogene Membransignale zu schließen, der verschwindet, wenn die Patienten nach Antibiotikatherapie geheilt sind.Keywords
