Simon Lumb, Sarah J. Fleischer, Annika Wiedemann, Capucine Daridon, more

Journal of Cell Communication and Signaling > 2016 > 10 > 2 > 143-151

The binding of antigen to the B cell receptor (BCR) results in a cascade of signalling events that ultimately drive B cell activation. Uncontrolled B cell activation is regulated by negative feedback loops that involve inhibitory co-receptors such as CD22 and CD32B that exert their functions following phosphorylation of immunoreceptor tyrosine-based inhibition motifs (ITIMs). The CD22-targeted antibody...
