DEF

A protein produced by macrophages in response to bacterial infection ...

CONT

Tumor necrosis factor(TNF) was originally discovered as a serum protein with necrotizing effects on certain transplantable mouse tumors in vivo and cytotoxic effects against some transformed cells in vitro. The TNF family consists of two proteins designated TNF-alpha, also called cachectin, and TNF-beta, also called lymphotoxin, which are pleiotropic cytokines that can mediate a wide variety of biological effects. TNF-beta is produced by activated lymphocytes, whereas TNF-alpha is mostly produced by activated macrophages.

OBS

A form made by genetic engineering is used in [some treatments].

OBS

In specialized works, the term «tumour necrosis factor» often makes reference to the tumour necrosis factor alpha.

CONT

Au cours des dernières années, on a mis en évidence un nombre croissant de protéines intervenant dans l'inflammation et l'immunité comme la croissance et l'inhibition cellulaires. Ces protéines, auxquelles on a donné le nom général de cytokines, comprennent […] le TNF […]

OBS

[…] on connaît actuellement la séquence du TNF de plusieurs espèces et on le fabrique par génie génétique.

OBS

Dans les ouvrages spécialisés, le terme «facteur de nécrose tumorale» fait souvent référence au facteur de nécrose tumorale alpha.

Subject field(s)
  • Hormones
CONT

Effects of uromodulin(URO) and Tamm-Horsfall protein(THP), the most abundant proteins in the urine of pregnant and normal women, respectively, on the induction of TNF-alpha secretion and tissue factor(TF) expression of human monocytes were studied. THP, URO, and its fragments stimulated human mononuclear cells to proliferate and secrete TNF-alpha.

French

Domaine(s)
  • Hormones
DEF

Glycoprotéine isolée et purifiée, à partir de l'urine de femmes enceintes, ayant des propriétés immunosuppressives : elle inhibe l'activité de certaines cellules impliquées dans l'immunité, notamment les lymphocytes T et les monocytes.

CONT

Insoluble peptidoglycan(PGN) from staphylococcal cell walls as well as soluble PGN(sPGN) secreted by staphylococci in the presence of beta-lactam antibiotics induced TNF-alpha mRNA and secretion of bioactive TNF-alpha in the murine RAW264. 7 macrophage cell line. PGN and sPGN also induced rapid and dose-dependent tyrosine phosphorylation of several cellular proteins, including lyn and mitogen-activated protein kinases(extracellular signal-regulated kinases; but not hck, fgr, or vav) and increased the activities of mitogen-activated protein and rsk kinases. These PGN-and sPGN-induced effects were qualitatively similar to the effects induced by ReLPS, but higher concentrations of PGN and sPGN than ReLPS were required.
