B-cell signalling via the C-type lectins CD23 and CD72.
Although CD23 and CD72 are well-known B-cell signalling molecules, the intracellular signal transduction pathways through which they operate remain poorly elucidated. This may partly reflect their somewhat dubious histories, with claims and counterclaims being made for functions and ligands. Here, John Gordon discusses why such controversy should surround the two B-cell-associated C-type lectins and provides speculation as to their respective roles in regulating an immune response that may be different in mice and humans.
