Blastogenic response of toxoplasma-infected mouse spleen cells to t- and b-cell mitogens.... Phytohaemagglutinin (PHA) and concanavalin A (Con A) stimulation were used as tests of thymus-dependent lymphocyte (T cell) function and bacterial endotoxin lipopolysaccharide (LPS) was used as a probe of bursal equivalent lymphocyte (B cell) function....
Rationale for combined use of fetal liver and thymus for immunological reconstitution in patients with variants of severe combined immunodeficiencyBone marrow cells from a patient with severe combined immunodeficiency were studied in vitro for thymus-dependent lymphocyte (T cell) differentiation by using, at varying times, thymic epithelial monolayers and culture supernatants, thymopoietin, ubiquitin, and thymic extract...
In vitro lymphocyte reactivity and t-cell levels in chronic cigarette smokers.Peripheral blood total leucocyte, lymphocyte and thymus-dependent lymphocyte (T cell) levels and in vitro lymphocyte reactivity (LR) to phytohaemagglutinin (PHA) were determined in 153 chronic cigarette smokers and 115 non-smokers...
