Mu-surrogate light chain physicochemical interactions of the human preB cell receptor: implications for VH repertoire selection and cell signaling at the preB cell stage.
The surrogate light chain (SL) composed of the A-like and VpreB polypeptides is organized as two Ig domains and an extra-loop structure. It associates to the mu-chain in preB cells. We have produced human VpreB, SL, two Fdmu (VH-CH1), and the two corresponding Fab-like (Fdmu-SL) recombinant proteins in baculovirus. The correctness of the general conformation of the proteins was assessed by epit...
متن کاملB cell receptor basal signaling regulates antigen-induced Ig light chain rearrangements.
BCR editing in the bone marrow contributes to B cell tolerance by orchestrating secondary Ig rearrangements in self-reactive B cells. We have recently shown that loss of the BCR or a pharmacologic blockade of BCR proximal signaling pathways results in a global "back-differentiation" response in which immature B cells down-regulate genes important for the mature B cell program and up-regulate ge...
متن کاملMechanisms of cGMP-dependent mesangial-cell relaxation: a role for myosin light-chain phosphatase activation.
Although the cGMP-dependent relaxation of contractile cells seems to depend on the ability of the cyclic nucleotide to interfere with intracellular calcium, this does not appear to be the only mechanism involved. The present experiments were designed to analyse alternative mechanisms, trying to test the hypothesis that cGMP could relax rat mesangial cells by activating myosin light-chain phosph...
متن کاملExpression and physical association of Fca receptor and Fc receptor c chain in human mesangial cells
Key words: FcaR; FcR c chain; IgA nephropathy; mesangial cells; physical association Background. Most intensive investigations on the pathogenesis of IgA nephropathy have focused on the process before IgA deposition and the characteristics of IgA/IgA immune complex (IgA IC), but it still Introduction remains uncertain whether mesangial IgA ICs may cause glomerular injuries directly or are only ...
متن کاملToll-Like Receptor 4 Signaling is Involved in IgA-Stimulated Mesangial Cell Activation
PURPOSE Deposition of polymeric IgA1 in the kidney mesangium is the hallmark of IgA nephropathy, but the molecular mechanisms of IgA-mediated mesangial responses and inflammatory injuries remain poorly understood. We hypothesize that Toll-like receptor 4 (TLR4) is involved in IgA-induced mesangial cell activation. MATERIALS AND METHODS Mouse mesangial cells were stimulated with lipopolysaccha...
