Nonspecific recruitment of lymphocytes in purified protein derivative-induced lymphocyte proliferative response of patients with tuberculosis. 1982

Peripheral blood lymphocytes (PBL) from tuberculosis patients were studied for their in vitro proliferative response stimulated with purified protein derivative (PPD)-tuberculin. Studies were designed to characterize the lymphocytes involved in the PPD-induced proliferation. PPD-responsive lymphocytes were eliminated in PBL by the procedure of cultivation of PBL with PPD in the presence of 5-bromodeoxyuridine and light illumination of the cultured cells. These PBL which lost PPD reactivity were no longer able to proliferate to PPD stimulation but were still capable of proliferation in the presence of both PPD and X-irradiated, autologous fresh PBL or upon addition of culture fluids from PPD-stimulated PBL. In addition, these nonspecifically activated lymphocytes released a soluble factor into the culture fluids which inhibited the migration of leukocytes. It was likely that large numbers of nonspecific T cells were induced to proliferate as a result of the presentation of specific T cells with the antigen PPD. It is suggested that a similar recruitment of lymphocytes by PPD-stimulated T cells takes place in vivo during the establishment of tuberculosis or antituberculous immunity or both.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D007961	Leukocyte Migration-Inhibitory Factors	Protein factor(s) released by sensitized lymphocytes (and possibly other cells) that inhibit the movement of LEUKOCYTES, especially polymorphonuclear cells, away from their site of release. Assays for these factors are used as tests for cellular immunity. Two of the common assays are the LEUKOCYTE MIGRATION CAPILLARY TUBE TECHNIQUE (LMCT) and the LEUKOCYTE MIGRATION AGAROSE TEST (LMAT).

D008029	Lighting	The illumination of an environment and the arrangement of lights to achieve an effect or optimal visibility. Its application is in domestic or in public settings and in medical and non-medical environments.	Illumination
D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D001973	Bromodeoxyuridine	A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumors.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
