Thymic hormone-containing cells. Characterization and localization of serum thymic factor in young mouse thymus studied by monoclonal antibodies
The characterization and distribution of cells containing the serum thymic factor (FTS) in the thymus of young mice was studied by immunofluorescence using monoclonal anti-FTS antibodies. FTS+ cells were distributed throughout the thymic parenchyma but were more frequent in the medullary region than in the cortex. FTS-containing cells presented a stellate or globular aspect, and some of them ex...
متن کاملSpecific receptors for the serum thymic factor (FTS) in lymphoblastoid cultured cell lines.
The interaction of the synthetic serum thymic factor (FTS, "facteur thymique sérique") with human T lymphocytes from two established T cell lines (1301 and HSB2) was studied by using [3H]FTS. At 30 degrees C, in the presence of 10 nM labeled FTS, a steady state was observed within 120 min. Bound labeled FTS was dissociated by simultaneous addition of an excess of unlabeled FTS (dissociation con...
متن کاملIsolation and characterization of a thymic factor.
A protein was isolated from bovine thymus that was shown to accelerate the appearance of hemolysin to sheep erythrocytes in neonatal mice. The isolation procedure consisted of saline homogenization, ammonium sulfate precipitation, and methanol precipitation, followed by chromatography on diethylaminoethyl-cellulose and two chromatographies on Sephadex G-150. The protein was shown to be homogene...
متن کاملProtective effect of thymic humoral factor on porcine serum-induced hepatic fibrosis and liver damage in Wistar rats.
INTRODUCTION Immunomodulatory drugs have been reported to have anti-inflammatory and anti-fibrotic properties. Thymic humoral factor (THF), a peptide produced in the thymus, causes a potent immunomodulatory effect on different components of the immune system. OBJECTIVE To evaluate the effect of THF on different stages of liver damage and fibrosis induced in rats through the administration of ...
متن کاملRegulation of thymic epithelium by keratinocyte growth factor.
Here we demonstrate that keratinocyte growth factor (KGF) and FGFR2IIIb signaling can affect development and function of thymic epithelium (TE) and that alphabeta-lineage thymocytes contribute to intrathymic levels of KGF. Thymocyte expression of KGF is developmentally regulated, being undetectable in CD3-4-8- thymocytes and expressed at highest levels by mature CD4 or CD8 thymocytes. Exposure ...
