B cell activation induced by cross-linking of CD40 is enhanced by costimulation with certain T cell-derived cytokines (generally Th2 type), most notably IL-4. We show here that the induction of DNA synthesis in normal mouse B cells by anti-CD40 mAb i

Cross-linking of sIgM or sIgD receptors on mature B cells with appropriate anti-Ig Abs normally induces B cell activation and DNA synthesis. We show here that hypercross-linking of either class of sIg receptor on these cells by biotinylated, normally

Protection against infection with encapsulated bacteria is mediated by IgG antibodies against the capsular polysaccharides. Production of such antibodies is impaired during infancy, when susceptibility to bacterial meningitis is greatest. Recent stud

Since signals via CD40 and the B cell receptor are known to synergize to induce B cell activation, we have analyzed the pocket protein/E2F complexes in mouse B lymphocytes following stimulation by anti-IgM, anti-CD40, alone or together. We find that

The interaction of CD40 on B cells with the CD40 ligand (CD40L) on preactivated CD4 T cells is critical for the initiation of T-dependent Ab responses. It is believed that signals via CD40 synergize with cytokines (e.g., IL-4 and IL-5) to drive B cel

The potent accessory properties of dendritic cells (DC) develop sequentially during a process termed "maturation." Splenic DC undergo functional maturation in vivo in response to the bacterial product LPS and migrate from the marginal zone to the T c

Guanine nucleotide regulatory (G) proteins control signalling via a variety of widely distributed cell surface receptors. Relatively little is known about the involvement of G-proteins in signal transduction via biologically important receptors on ly

Concanavalin A (Con A) induces DNA synthesis in bulk cultures of murine T cells. In contrast, the lectin has been shown to stimulate purified B cells to leave G0, but not to proliferate. We demonstrate here that Con A induces comparable increases in

We have recently described three "immature" B cell lymphomas which are exquisitely sensitive to growth inhibition by anti-Ig reagents and may serve as models for tolerance induction in normal B cells. These cells are inhibited from cell cycle progres

Cross-linking of the IgM and IgD Ag-R on mature B lymphocytes provokes the rapid hydrolysis of phosphatidylinositol 4,5-bisphosphate. We show here that in permeabilized, [3H]inositol-labeled mouse B cells the nonhydrolyzable GTP analogue GTP gamma S
