Dual role of Cbl links critical events in BCR endocytosis.

Receptor endocytosis down-regulates ligand-induced signaling in a timely manner and depends on cytoskeletal remodeling. In B lymphocytes, internalization of B cell receptors (BCRs) is also critical to antigen presentation. However, the mechanisms underlying BCR endocytosis are not fully understood.

A crucial role for CD44 in inflammation.

Current therapies for chronic inflammatory diseases typically act through the nonspecific downregulation of immune cell activation. However, it is becoming increasingly evident that parenchymal cells are also active participants in the inflammatory process. Future prospects for the treatment of inflammation should therefore include the targeting of specific inflammatory pathways in both immune cells and parenchymal cells.
