Immunopharmacology Comments
MALT1 inhibition is considered a tractable mechanism for the treatment of severe autoimmune diseases. The MALT1 inhibitory action of pecazine (a.k.a. mepazine) is reported to be effecacious in the mouse experimental autoimmune encephalomyelitis (EAE) model of multiple sclerosis [1].

General Comments
MALT1 acts as a scaffolding protein in the formation of the CARD11-BCL10-MALT1 (CBM) signalosome complex and promotes the recruitment of signaling factors (e.g. TRAF6, TAK1 and NEMO) [4]. MALT1 genetic translocations have been identified in mucosa-associated lymphoid tissue (MALT) lymphoma, that cause constitutive NF-κB activation, malignant B cell transformation and tumorigenesis [4-5]. The caspase activity of MALT1 is required for activation of NF-κB and optimal T cell activation. MALT1 inhibitors have been shown to kill MALT1-dependent lymphomas in vitro and in vivo [2].
