7 unusual facts about T cell


Entry inhibitor

# The penetration of the cell membrane by gp41, which approximates the membrane of HIV and the T cell and promotes their fusion

CD4, a protein receptor found on the surface of helper T cells in the human immune system, also called CD4+ T cells

Hermann Wagner

From 1970-80 he analysed T-T Cell interactions during the induction of cytotoxic T Cell responses <1>.

From 1973 to 1983 he continued his research on " T Cell mediated Immune Responses" with Paul Klein at the Institut of Microbiology of the Johannes-Gutenberg University in Mainz/Germany.

HIV disease progression rates

The appearance of HIV-1-specific CD8+ cytotoxic T cells (CTLs) early after primo-infection has been correlated with the control of HIV-1 viremia.

Long-term nonprogressor

A low percentage of long-term nonprogressors have been shown to have inherited mutations of the CCR5 receptor of T cell lymphocytes.

Skin immunity

Lymphocytes move to the epidermis where they reside as a memory T cells, they will thus be activated and will trigger inflammatory response.


Cytokine release syndrome

Cytokine release syndrome is a common immediate complication occurring with the use of anti-T cell antibody infusions such as ATG, OKT3 and TGN1412, but also with the CD-20 antibody rituximab.

Tetrabromobisphenol A

TBBPA likely also suppresses immune responses by inhibiting expression of CD25 receptors on T cells, preventing their activation, and by reducing natural killer cell activity.

Butyrate

It has been shown that Butyrate inhibits activity of HDAC1 that is bound to the Fas gene promoter in T cells, resulting in hyperacetylation of the Fas promoter and up-regulation of Fas receptor on the T cell surface.

Cholinergic urticaria

Elevated expression levels of CCL2/MCP-1, CCL5/RANTES and CCL17/TARC which result in chemoattracted CD4+ and CD8+ T cell populations to the surrounding area may be responsible for exerting a downmodulatory effect on the AchE and CHRM3 expressions.

Emil R. Unanue

That observation, called MHC restriction, led to a conundrum; namely, that the ability of a T cell to recognize foreign antigen also required that it recognize "self." With Paul M. Allen, Ph.D., the Robert L. Kroc Professor at Washington University School of Medicine, Unanue discovered that peptides from foreign antigens were bound to a group of molecules known as the major histocompatibility complex (MHC).

Enteropathy-associated T-cell lymphoma

Enteropathy associated T-cell lymphoma (EATL) is environmentally induced as a result of the consumption of Triticeae glutens (e.g. wheat gluten).

Extracellular signal-regulated kinases

Mice lacking MAPK3 have reduced T cell development past the CD4+CD8+ stage.

Interleukin 2

It was initially called T cell growth factor, but the name was changed in 1978 to IL-2 (interleukin-2) by the Interlaken cytokine nomenclature committee.

Lymphoid enhancer-binding factor 1

It binds to a functionally important site in the T-cell receptor-alpha (TCRA) enhancer and confers maximal enhancer activity.

T cell deficiency

The main pathogens of concern in T cell deficiencies are intracellular pathogens, including Herpes simplex virus, Mycobacterium and Listeria.

Transition state theory

Purine nucleoside phosphorylase (PNP) is an enzyme involved in the catabolism and recycling of nucleosides and is a target for the development of novel therapeutic agents for T-cell apoptosis in leukemia and in autoimmune diseases.
