Emergence of a surface immunoglobulin recycling process during B lymphocyte differentiation
Surface immunoglobulin (Ig)-mediated endocytosis has been investigated in rat B lymphocytes and plasma cells, using horseradish peroxidase (HRP)-labeled sheep anti-rat Ig Fab' fragment of antibody and HRP as monomeric ligands, respectively. Quantitative estimates of HRP activity associated either with plasma membrane or with endomembrane compartments were made in several experimental conditions...
متن کاملRNA-binding protein hnRNPLL regulates mRNA splicing and stability during B-cell to plasma-cell differentiation.
Posttranscriptional regulation is a major mechanism to rewire transcriptomes during differentiation. Heterogeneous nuclear RNA-binding protein LL (hnRNPLL) is specifically induced in terminally differentiated lymphocytes, including effector T cells and plasma cells. To study the molecular functions of hnRNPLL at a genome-wide level, we identified hnRNPLL RNA targets and binding sites in plasma ...
متن کاملDelay of Early B-Lymphocyte Development by Gamma 2b Immunoglobulin Transgene: Effect on Differentiation-Specific Molecules
Mice transgenic for gamma 2b Ig heavy chain were examined for alterations in B-cell differentiation and endogenous Ig gene rearrangement and expression. Fresh bone marrow from these mice was markedly reduced in BP-1+ cells and there were small reductions in B220+ and sIg+ cells. A-MuLV (Abelson murine leukemia virus) transformants from these bone marrow cells showed little alteration in Ig gene...
متن کاملThe half-life of immunoglobulin mRNA increases during B-cell differentiation: a possible role for targeting to membrane-bound polysomes.
The increase in abundance of immunoglobulin heavy-chain (IgH) mRNA that accompanies development of a B cell into a plasma cell is mainly due to post-transcriptional events. By constructing mu genes, whose expression is under inducible control, we determined the half-life of pulsed mu transcripts to be approximately 20 hr in plasmacytoma hosts and approximately 3 hr in B-cell lymphomas. Interest...
متن کاملModulation of human B lymphocyte differentiation by therapeutic immunoglobulins: from protein to mRNA levels
Several groups are investigating the mechanisms of action of therapeutic immunoglobulins (IVIg) in order to improve their use. In vitro models such as CD40-CD154 interaction are necessary to study the physiological response of human B lymphocytes to IVIg. Human B lymphocytes treated with IVIg triggers a rapid phosphorylation (<1 h) of extracellular-regulatedkinases 1 and 2 (ERK1/2), which subse...
