Background: Herpesvirus infections are one of the most common human that play a special role in children with recurrent respiratory infection cohort formation. The immunological status such is characterized by an imbalance all links immunity. aim study: To study RRI and to analyze association SNP -330T>G IL2 -1082G>A IL10 relative absolute values main subpopulations lymphocytes. Materials...

Studies have shown that CD1 double negative mice (CD1d) develop larger liver abscesses due to their inability to present amebic antigens to NK T lymphocytes. Therefore, we conducted flow cytometry studies to determine the frequency of NK T, CD4 T, CD8 T and B lymphocytes in mice with amebic colitis. The frequency of NK T, CD8 T and B lymphocytes was reduced in the MLN of mice in the CTRL-CD1 an...

T cell concerned with cell mediated immunity and B cell concerned with humoral antibody are classified by scanning electron microscopy of the surface structure of lymphocytes using E binding lymphocytes and EAC (sensitized sheep erythrocytes treated with complement) binding lymphocytes. For the purpose to elucidate morphological differences between T cell and B cell the scanning electron micros...

Although most leukocytes, T lymphocytes in particular, respond to several different chemokines, there is virtually no information on chemokine activities and chemokine receptors in B lymphocytes. A putative chemokine receptor, BLR1, that is expressed in Burkitt's lymphoma cells and B lymphocytes was cloned a few years ago. Deletion of the gene for BLR1 yielded mice with abnormal primary follicl...

Cells of the monocyte/macrophage lineage, dendritic cells, and a variety of other cell types that express class II histocompatibility (Ia) molecules on their surfaces are capable of presenting foreign protein antigens to and stimulating Iarestricted inducer (helper) T lymphocytes (1-3). After the demonstration that B cells also bear Ia antigens (4) and that at least some interactions between an...

Rhesus monkeys were immunized with normal human lymphoid cells, cultured lymphoid cells, and chronic leukemic lymphocytes. Antisera were analyzed by cytotoxicity and immunofluorescence techniques to study the antigenic characteristics of human lymphocytes. In an attempt to obtain a reagent specifically reactive with T (thymus-derived) lymphocytes, an antispleen antiserum was absorbed with cellf...

The relative ability of Th1 and Th2 T cells to help B cells remains controversial as do the mechanisms by which both T cell subsets provide help in vivo. Whether this help affects the clonal expansion and/or differentiation of B cells has been difficult to assess due to the low frequency of Ag-specific T and B lymphocytes. We have employed a novel technique to directly monitor the clonal expans...
