Lymphocyte Proliferation and Gamma - Interferon Production after “ in Vitro ” Stimulation with PPD *
نویسنده
چکیده
T-lymphocytes previously sensitized by an antigen undergo blastic transformation and produce IFN’r when stimulated by the same antigen. We studied the lymphoblastic response to PPD and IFNT production in pleural fluid and peripheral blood of 41 patients (15 with tuberculosis pleural effusion, 13 with nontuberculous pleurisy and positive tuberculin skin test, and 13 with tuberculin-negative nontuberculous

Lymphocyte subset proliferative responses of Mycobacterium bovis-infected cattle to purified protein derivative.
Despite highly successful eradication efforts in several countries, Mycobacterium bovis infection of cattle remains a significant health concern worldwide. Immune mechanisms of resistance to and/or clearance of M. bovis infection of cattle, however, are unclear. Recent studies have provided evidence supporting a role for CD4(+), CD8(+), and gammadelta TCR(+) T cells in the response of cattle to...
متن کاملImmunologic Evaluation of DNA Vaccine Encoding Influenza Virus M2 Gene in Type A- Influenza Mice Model
Abstract Background and Objective: The M2 gene expressing the conserved protein in influenza virus can be used to make a single-dose vaccine with permanent immunity. Material and Methods: The mice were allocated to one case group immunized with pcDNA3-M2 and two control groups with pcDNA and PBS, in three dozes with interval of two weeks. Two weeks after the last injection, Cellular imm...
متن کاملIn vitro lymphoproliferative response and cytokine production in mice with experimental disseminated candidiasis
Objective(s): Systemic candidiasis is an infection of Candida albicans (C. albicans) causing disseminated disease and sepsis, invariably when host defenses are compromised. We investigated the histopathological changes as well as the lymphoproliferative responses and cytokine production of splenic cells after stimulation with Concanavalin A (Con A) and Pokeweed mitogen (PWM) in mice with dissem...
متن کاملReduced IFN-γ Production in Chronic Brucellosis Patients
Background: Brucella is a well-known intracellular bacterium entailing acute and chronic illnesses in humans and domestic animals. The infection chronicity may be affected by the cell-mediated immunity and cytokine patterns. Objective: To evaluate the patterns of T-helper cytokines in patients suffering from chronic and acute brucellosis. Methods: In this cross-sectional study, 22 individuals w...
متن کاملSensitization to inorganic mercury could be a risk factor for infertility.
INTRODUCTION Heavy metals can negatively influence the reproduction due to the fact that they are able to impair the immune reactions including autoantibody production in susceptible individuals. In such a way the infertility could be also caused by altered pathologic immune reaction. AIM OF THE STUDY To investigate the in vitro lymphocyte reaction after stimulation with metals and production...
