The Physiological Significance of Ganglioside Species Selectively Expressed on Individual T Cell Subsets

The Immunomodulatory Effect of Cyclophosphamide on Regulation of T-Cell Subsets and Antigen Presenting Cells.

the effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions

two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...

On the Mechanism of T cell receptor down-modulation and its physiological significance.

Effective, long-lasting immune responses largely depend upon T cell reponses. Antigen-specific T lymphocytes are activated and differentiate into effector T cells after antigen presentation by professional antigen presenting cells (APCs). However, T cell responses are tightly regulated to prevent T cell hyperactivation which may end up in autoimmune pathology. One of these regulatory mechanisms...

The T-cell activation markers CD30 and OX40/CD134 are expressed in nonoverlapping subsets of peripheral T-cell lymphoma.

The tumor necrosis factor (TNF) receptor family includes several important markers of activation in T cells. We examined expression patterns of two T-cell-associated members of these receptors, namely CD30 and OX40/CD134, in 148 cases of T-cell lymphoma to identify possible objective immunohistochemical criteria for subclassification of these tumors. CD30 expression was characteristic of tumors...

CD93 is Selectively Expressed on Human Myeloma Cells but Not on B Lymphocytes

Background: CD93 has originally been known as a C1q receptor, and many studies have demonstrated that CD93 is expressed on hematopoietic stem cells, B cell progenitors, myeloid and monocytic cells. Moreover, CD93 is shown to be expressed on long-lived plasma cells, and CD93 deficient-mice display an impairment in plasma cell development. Objective: To investiga...
