How T-lymphocytes are activated and become activators by cell-cell interaction.
Immunological descriptions support the role of direct contact between T-lymphocytes and monocytes at the site of inflammatory lesions. The following will therefore focus on the role of direct contact between stimulated T-lymphocytes and monocytes in the production of cytokines and cytokine inhibitors, as well as matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMP) ...
متن کاملActivated CD4+CD25+ T cells selectively kill B lymphocytes.
The suppressive capacity of naturally occurring mouse CD4+CD25+ T cells on T-cell activation has been well documented. The present study is focused on the interaction of CD4+CD25+ T cells and B cells. By coculturing preactivated CD4+CD25+ T cells with B cells in the presence of polyclonal B-cell activators, we found that B-cell proliferation was significantly suppressed. The suppression of B-ce...
متن کاملChanges in T and B blood lymphocytes after splenectomy.
The blood lymphocytes of 37 splenectomised patients were analysed by means of T and B lymphocyte surface markers. Sixteen patients had had a splenectomy for non-haematological and 21 for haematological reasons. The results show that 15 had normal numbers of T and B cells; decreased T cells were found in two patients, raised B cells in seven, raised T and B cells in eight, and raised T cells in ...
متن کاملActivated T lymphocytes in uveitis.
Two colour flow cytometry techniques were used to assess the activation stages of peripheral and intraocular T lymphocytes in uveitis. Increased numbers of T lymphocytes bearing the interleukin-2 (IL-2) receptors were found in intraocular fluids or peripheral blood or both of 35/51 patients with uveitis. This increased expression of IL-2 receptors on lymphocytes correlated with increased expres...
متن کاملActivity of T-Helper Lymphocytes in Opium Dependent and Non-dependent Individuals
Opium derivatives affect the function and differentiation of peripheral leucocytes, directly or indirectly. Previous researches have shown that these cells respond to the endorphins through their opioid receptors (σ, µ and κ). There are many reports about the effect of morphine and heroin on immune system of dependent people, but there is no report on the functions of T-helper lymphocytes in op...
