autoimmunity induced by excessive BAFF (show TNFSF13B ELISA Kits) production requires B1b B cells and CD19 signaling.
WIPF1 (show WIPF1 ELISA Kits) deficiency impaired CD19 co-receptor activation and subsequent PI3 kinase (show PIK3CA ELISA Kits) signaling, by distorting the actin and tetraspanin networks that lead to altered CD19 cell surface dynamics.
Syk (show SYK ELISA Kits)-deficient B cells require BAFF receptor (show TNFRSF13C ELISA Kits) and CD19/PI3K signaling for their long-term survival.
The selection of mature B cells is critically dependent on the expression level of the co-receptor CD19.
This inhibitory function of FcgammaRIIB in impairing the spatial-temporal colocalization of BCR (show BCR ELISA Kits) and CD19 microclusters in the B cell immunological synapse may help explain the hyper-reactive features of systemic lupus erythematosus
These results show that the ability of CD19-CAR T-cells to home in on tumor lesions is pivotal for their anti-tumor effects in our xenograft models, and therefore may enhance the efficacy of adoptive T-cell therapy for refractory B-cell lymphoma.
Data show that effective B cell receptor (BCR (show BCR ELISA Kits)) signaling requires collaboration with the coreceptor CD19 organized by the CD81 (show CD81 ELISA Kits)-tetraspanin network.
results indicate that the CD19/CD81 complex interacts with CD38 but this interaction is not required to induce proliferation in mouse B lymphocytes
CD19positive CD45R (show PTPRC ELISA Kits)(lo)positive lymphocytes of embryonic origin are present in Peyer's patches and in the spleen throughout the life span of wild-type mice, beginning at postnatal day 7.
We report that regulatory dendritic cells can induce splenic B cells to differentiate into a distinct subtype of IL-10 (show IL10 ELISA Kits)-producing regulatory B cells with unique phenotype CD19(hi)FcgammaIIb(hi).
CD19 is required for TLR9 (show TLR9 ELISA Kits)-induced B-cell activation (show BLNK ELISA Kits). Hence CD19/PI3K (show PIK3CA ELISA Kits)/AKT (show AKT1 ELISA Kits)/BTK (show BTK ELISA Kits) is an essential axis integrating BCRs and TLR9 (show TLR9 ELISA Kits) signaling in human B cells.
High anti-EBV IgG levels in Crohn's disease are associated with 5-aminosalicylic acid treatment, tonsillectomy, and decrease of CD19(+) cells.
We propose that CD81 (show CD81 ELISA Kits) enables the maturation of CD19 and its trafficking to the membrane by regulating the exit of CD19 from the ER to the pre-Golgi compartment
we outline our approach to nonviral gene transfer using the Sleeping Beauty system and the selective propagation of CD19-specific CAR(+) T cells on AaPCs
We demonstrate that this motif plays a role in the maturation and recycling of CD19 but in a CD81 (show CD81 ELISA Kits)-independent manner.
Studies indicate that anti-CD19 and anti-CD33 (show CD33 ELISA Kits) bispecific antibodies showed anticancer activity.
The synaptic recruitment of lipid rafts is dependent on CD19-PI3K (show PIK3CA ELISA Kits) module and cytoskeleton remodeling molecules.
propose a multilayer model of plasma cell (PC) memory in which CD19(+) and CD19(-) PC represent dynamic and static components, respectively, permitting both adaptation and stability of humoral immune protection
Suppression of innate and adaptive B cell activation (show BLNK ELISA Kits) pathways by antibody coengagement of FcgammaRIIb and CD19.
Human CD19 and CD40L (show CD40LG ELISA Kits) deficiencies impair antibody selection and differentially affect somatic hypermutation.
DNA sequence analysis of the coding sequence of CD19, the CR2 co-signaling molecule.
Lymphocytes proliferate and differentiate in response to various concentrations of different antigens. The ability of the B cell to respond in a specific, yet sensitive manner to the various antigens is achieved with the use of low-affinity antigen receptors. This gene encodes a cell surface molecule which assembles with the antigen receptor of B lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.
