THE INTERACTION OF IgE WITH RAT BASOPHILIC LEUKEMIA CELLS
A rat basophilic leukemia cell line originally described by Eccleston et al. (3) has been successfully transplanted into eight Wistar strains and adapted to suspension cell culture without noticeable morphological changes. The cells deplete the reaginic activity of mouse and rat immune sera to an extent roughly equivalent to that reported for normal rat mast cells. Studies utilizing radioiodina...
متن کاملMembrane-bound IgE receptor complexes fused with rat basophilic leukemia cells mediate degranulation
The high affinity receptor for IgE on rat basophilic leukemia (RBL) cells mediates antigen-triggered cellular degranulation. Polyethylene glycol-induced membrane fusion methods were used to introduce exogenous IgE receptors into living RBL cells, and these were tested for normal activities. In cell-cell fusion experiments, RBL cells with fluorescein-labeled rat IgE bound to receptors and contai...
متن کاملEvaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...
متن کاملFlotillin-1 regulates IgE receptor-mediated signaling in rat basophilic leukemia (RBL-2H3) cells.
Cross-linking of high-affinity IgE receptors by multivalent Ag on mast cells (rat basophilic leukemia (RBL)-2H3) induces the phosphorylation of ITAM motifs of an IgE receptor by Src family tyrosine kinase, Lyn. The phosphorylation of IgE receptors is followed by a series of intracellular signals, such as Ca(2+) mobilization, MAPK activation, and degranulation. Therefore, Lyn is a key molecule i...
متن کاملAssociation of VNTR polymorphism of tumor necrosis factor receptor 2 (TNFRSF1B) with pulmonary tuberculosis
This study was designed to find out the impact of the variable number of tandem repeats (VNTR) of the tumor necrosis factor receptor 2 (TNFRSF1B) on pulmonary tuberculosis (PTB) risk in an Iranian population. This case-control study was done on 159 PTB patients and 158 healthy subjects. Bi-allelic TNFRSF1B VNTR was genotyped by polymerase chain reaction. Logistic regression analysis revealed no...
