T-lymphocyte differentiation is accompanied by increase in sialic acid content of Thy-1 antigen
Nature, 1980Lymphocyte differentiation is accompanied by changes in the expression of various glycoproteins at the cell surface 1–4. Whether changes in the structures of individual glycoproteins, as opposed to changes in then expression, also occur during this differentiation is not known.

Exogenous and endogenous antigens are differentially presented by mast cells to CD4+ T lymphocytes
European Journal of Immunology, 1996AbstractIn the present work, we explored the cytokine‐dependent regulation of bone marrow‐derived mast cell (BMMC) antigen‐presenting cell (APC) function, and co‐stimulation requirements, and analyzed the nature of antigens presented to T cells. We observed an up‐regulation of the APC function of mast cells induced by granulocyte/macrophage‐colony ...

Recognition of cluster of differentiation 1 antigens by human CD4−CD8>− cytolytic T lymphocyte
Nature, 1989Human cluster-of-differentiation 1 (CD1) is a family of cell surface glycoproteins of unknown function expressed on immature thymocytes, epidermal Langerhans cells and a subset of B lymphocytes. Three homologous proteins, CD1a, b and c, have been defined serologically, and the CD1 gene locus on human chromosome 1 contains five potential CD1 genes ...

Expression of T cell differentiation antigens and Ia on rat cytotoxic T lymphocytes.
The Journal of Immunology, 1982Abstract Study of lymphocyte subsets has been facilitated by the detection of various surface markers that are related to distinct functions. We have explored the use of affinity methods for separation of large quantities (10(8)) of rat cells and used this technique to identify surface markers of cytotoxic T lymphocytes. Splenocytes from

[Antigen recognition and differentiation of T lymphocytes].
Hematology and cell therapy, 1998During their intrathymic development, T lymphocytes acquire the ability to recognize myriads of antigens bound to self major histocompatibility molecules. This property is linked to the activation at early stages of thymic development of the biosynthesis of the antigen recognition receptors, the T cell receptors.

Differentiation antigens expressed predominantly on CD4− CD8− T lymphocytes (WC1, WC2)
Veterinary Immunology and Immunopathology, 1991Abstract The 14 mAbs representing workshop cluster 1 recognise a 215 300 kDa antigen expressed on a subpopulation of lymphocytes which express low levels of CD5 but are negative for other B and T cell markers defined by workshop antibodies. Separate studies with cDNA probes for bovine CD3 and T cell receptor indicate that these lymphocytes ...

Differential Ras signaling via the antigen receptor and IL-2 receptor in primary T lymphocytes
Biochemical and Biophysical Research Communications, 2003Ras can become activated via multiple distinct receptors in T lymphocytes. However, mechanistic studies of Ras signaling in normal T cells have been hampered by the lack of an efficient technology for gene transfer into resting post-thymic cells. We have overcome this limitation by utilizing adenoviral transduction of T cells from Coxsackie/adenovirus ...

Abstract Alloreactive CTL raised against HLA-A2 Ag often display heterogeneous recognition of HLA-A2+ target cells. This heterogeneity has been found to reflect structural polymorphism among the corresponding target Ag, thus defining HLA-A2 subtypes. A previous study (van der Poel et al. 1986. Human Immunol.

The results presented in this paper demonstrate that a mouse IgM monoclonal antibody (T-80) recognizes an antigen on cells of the T-lymphocyte lineage of sheep. However, this antibody does not identify all T cells, as 10-20% of thymocytes and some peripheral-blood T cells are negative. T-80- thymocytes reside in the medulla.

SUMMARYAnti‐reovirus cytotoxic effectors were found to be: (i) H‐2 restricted; (ii) virus specific; (iii) non‐lytic (in 4 h) for natural killer (NK)‐sensitive YAC‐1 cells; and (iv) positive for the Thy‐1 and Lyt‐2 lymphocyte markers. Thus, anti‐reovirus cytotoxic effectors have the functional and phenotype characteristics of cytotoxic T lymphocyte (CTL)
