Immunopharmacology Comments
SYK plays a key role in coupling activated immunoreceptors to downstream cellular responses such as proliferation, differentiation, and phagocytosis. Mast cell, macrophage and B-cell activation (and release of inflammatory modulators) is disrupted by inhibition of SYK-mediated immunoreceptor signalling. Selective SYK inhibitors are being sought for a number of inflammatory conditions including rheumatoid arthritis, B-cell lymphoma and asthma/rhinitis [11,22].

The first SYK inhibitor to receive FDA approval was fostamatinib (April 2018), which was authorised for the treatment of persistent/chronic adult immune thrombocytopenia (ITP) [21]. In ITP, SYK-mediated signal transduction in macrophages drives the phagocytosis and destruction of autoantibody-coated platelets.
