Text-mined interactions from Literome
Fujimoto et al., J Biol Chem 2001
:
Although simultaneous CD19 and
BCR engagement significantly
enhanced CD19/Lyn complex formation and [ Ca ( 2+ ) ] ( i ) responses, downstream tyrosine phosphorylation of CD22 and multiple other cellular proteins was inhibited, as was SHP1 recruitment to phosphorylated CD22
Cherukuri et al., J Immunol 2004
:
When coligated to the B cell Ag receptor (BCR), the
CD19/CD21 complex significantly
enhances BCR signaling in part by prolonging the association of the BCR with signaling-active lipid rafts ... Using B cells from CD81-deficient mice we demonstrate that in the absence of CD81, coligated BCR and
CD19/CD21 complexes fail to partition into lipid rafts and
enhance BCR signaling from rafts
Ogimoto et al., Int Immunol 2004
(Calcium Signaling) :
We found that
BCR mediated phosphorylation of CD19, Btk, Vav and phospholipase Cgamma2 and association of
CD19 with phosphatidylinositol-3 kinase were impaired in CD72-deficient cells
Shao et al., J Biol Chem 2004
:
Interestingly, Cbl-/- B cells display enhanced
BCR induced phosphorylation of
CD19 and its association with phosphatidylinositol 3-kinase
Lee et al., J Immunol 2005
:
SA-C3dg enhancement of
BCR induced [ Ca2+ ] i responses required CD21 and CD19 expression and
resulted in significantly enhanced
CD19 and Lyn phosphorylation, with enhanced Lyn/CD19 associations ... By contrast, CD19/CD21 ligation using higher concentrations of SA-C3dg significantly inhibited
BCR induced [ Ca2+ ] i responses and
inhibited CD19 , Lyn, CD22, and Syk phosphorylation
Fujimoto et al., J Dermatol Sci 2007
(Autoimmune Diseases) :
CD19 and CD22 do not merely
regulate BCR signals independently, but they have their own regulatory network
Dasu et al., Mol Immunol 2009
:
The
CD19 induced Ca ( 2+ ) response and
BCR induced proliferation response were
restored by a partial inhibition of pLyn with Src kinase specific inhibitors
Ishiura et al., Eur J Immunol 2010
(Lymphoma, B-Cell) :
BCR engagement
induced differential tyrosine phosphorylation, as CD19-Y ( 513 ) phophorylation occurred first, and
CD19-Y ( 482 ) phosphorylation was delayed and transient ... Different BCR isotypes exhibited distinct patterns of CD19 phosphorylation :
IgG-BCR ligation
resulted in faster phosphorylation of
CD19-Y ( 513 ) and more intense phosphorylation of CD19-Y ( 391 ) than IgM-BCR ligation
Sato et al., Proc Natl Acad Sci U S A 1997
:
Ligation of
CD19 and CD22 in vivo is likely to positively and negatively
regulate BCR signaling, respectively, because CD19 crosslinking was more efficient than BCR crosslinking at inducing Vav phosphorylation
