B-cell signaling: protein kinase Cdelta puts the brakes on.
The phenotype of mice lacking the delta isoform of protein kinase C reveals that this isoform curtails signaling events after engagement of the antigen-specific receptor on B cells. The result is a state of non-responsiveness, termed anergy, that represents one form of immunological self-tolerance.
