Immunity to coccidiosis: T-lymphocyte- or B-lymphocyte-deficient animals

A SURVEY OF CELLULAR IMMUNITY, TOTAL T-LYMPHOCYTE, T-ACTIVE , B-LYMPHOCYTE A ND T-CELL FUNCTION IN RELATION TO PHYTOHEMAGGLUTININ (PHA) IN THALASSEMIC PATIENTS

The aim of this study was to evaluate the immune system and lymphocyte function in 41 Iranian β-thalassemic patients and 50 controls, ages ranging from 2 to 18 years. The patients consisted of 20 splenectomized and 21 non-splenectomized patients. They were treated with Desferal, and had received repeated blood transfusion. Laboratory investigations included measurement of total T lymphocyt...

How Aging Affects T Lymphocyte-Mediated Immunity

age-dependent decline in immune responses while autoimmune diseases increase in incidence. The authors hypothesize that the same defects that account for the decreased ability to generate protective immune responses also contribute to the increased risk of autoimmunity. The major risk factor for autoimmunity in old age appears to be the reshaping of the peripheral T cell receptor repertoire, wh...

T lymphocyte-dependent B lymphocyte proliferative response to antigen. I Genetic restriction of the stimulation of B lymphocyte proliferation

For the purpose of examining more closely the interaction between T and B lymphocytes, we have developed an in vitro T lymphocyte-dependent B lymphocyte proliferation assay. Proliferation of B lymphocytes in response to antigen was found to depend on the presence of primed T lymphocytes; the B lymphocytes could be derived from nonprimed animals. It appears that these B cells were nonspecificall...
