Functional subsets of lymphocytes.
In this review I shall survey various properties of lymphocytes which allow clear distinctions to be drawn between different lymphocyte subsets. I shall discuss only thymus-derived (T) lymphocytes since these cells appear to play a key role in regulating the activities of other lymphoid cells (B cells and macrophages) as well as carrying out effector functions themselves. In the first section I...
متن کاملDemonstration of Functional Heterogeneity of T lymphocytes and Identification of Their Two Major Subsets
Cells responsible for the specificity of the immune response and thymus function remained unknown until mid 1960s when lymphocytes were identified as mediators of cellular and humoral immunity (1–4). Soon afterward in vivo reconstitution experiments showed that cellular and humoral immunity are mediated by two different types of lymphocytes: thymusderived T cells and thymus-independent, bone ma...
متن کاملFunctional heterogeneity of lymphocytic choriomeningitis virus-specfic T lymphocytes. I. Identification of effector amd memory subsets
At varying intervals after immunizing infections of adult BALB/c mice with lymphocytic choriomeningitis (LCM) virus, splenic lymphocytes were tested for their ability to either elicit acute LCM or protect against lethal intracerebral LCM virus challenge when transferred to syngeneic recipients that were, respectively, virus carriers induced by cyclophosphamide-induced immunosuppression and norm...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولDetermination of lymphocytes surface markers in patients with thermal burns and the influence of burn size on mononuclear cell subsets
Background: Thermal burn injuries impair the host defence system. Hence, in the present study, we aimed at investigating the changes in the number and phenotype of peripheral blood lymphocyte populations (T, B, and natural killer cells) and their subpopulations in patients with thermal burns and determining the relationships with different sizes of total body surface area (TBSA). ...
