Role of Bruton's tyrosine kinase in B cell development; Btk is activated by Toll-like receptor (TLR)4 in primary macrophages and is required for normal TLR-induced IL-10 production in multiple macrophage populations. We discuss the role of BTK within the B cell receptor (BCR) signaling cascade and BTK inhibition as a promising strategy to control inflammatory CNS disease which crucially excludes immune-cell depletion.

Lowry WE, Huang X-Y. Harmful consequences arise when the immune system mistakes self-proteins as foreign antigens, with BTK promoting autoantibody secretion by autoreactive B cells.8,14,15 Autoimmune diseases such as multiple sclerosis (MS)16 result from this dysregulated production of autoantibodies, which leads to destruction of normal tissue.17 Malfunctioning BTK mutants have been linked to increased disease susceptibility, correlating with diminished numbers of mature B cells and immunoglobulin isotypes.18,19 BTK therefore serves as an important target for therapeutic agents that modulate innate immunity. 1994;91(23):11256-11260.

Multiple sclerosis (MS) is a debilitating, chronic demyelinating disease of the central nervous system affecting over 2 million people worldwide. Interactions between T cells, B cells, and myeloid cells promote MS pathology,16 and BTK is a component of signaling events with a critical role in regulating hematopoietic cell circulation.20 MS is a chronic, inflammatory, demyelinating disease of the central nervous system21 and is the most common, nontraumatic, disabling neurological autoimmune disease, with approximately 2.3 million cases diagnosed worldwide.22 B cells contribute to MS pathogenesis as a result of being skewed toward a proinflammatory profile involving antibody production, antigen presentation, T-cell stimulation, production of proinflammatory cytokines, formation of ectopic meningeal germinal centers, and deposition of oligoclonal bands of immunoglobulin in areas of active demyelination.23-25 Briefly, the body’s immune system begins to attack myelin, a protective sheath covering nerve fibers.
