Platelet FcγRIIA signaling: new clues for HIT.
In this issue of Blood, Zhou et al provide novel insights into Fc gamma type 2 receptor A (FcgRIIA)–mediated platelet activation. By identifying a negative regulator of FcgRIIA signaling, which is influenced by microRNA miR-148a, they present the first evidence of modulation of platelet function by microRNAs in vivo. They show that inhibition of miR-148a prevents thrombosis after immune complex...
متن کاملSecond-generation inhibitors of Bruton tyrosine kinase
Bruton tyrosine kinase (BTK) is a critical effector molecule for B cell development and plays a major role in lymphoma genesis. Ibrutinib is the first-generation BTK inhibitor. Ibrutinib has off-target effects on EGFR, ITK, and Tec family kinases, which explains the untoward effects of ibrutinib. Resistance to ibrutinib was also reported. The C481S mutation in the BTK kinase domain was reported...
متن کاملBTK (Bruton agammaglobulinemia tyrosine kinase)
The BTK protein is a 77 kDa protein of 659 amino acids. Translation of the BTK transcript starts at the ATG site that is located in exon 2 and ends in exon 19. The BTK protein is composed of an N-terminal Pleckstrin homology (PH) domain followed three protein interacting domains: Tec homology (TH) region, Src homology 3 (SH3) domain and SH2 domain. A tyrosine-kinase catalytic domain is located ...
متن کاملBruton ’ s Tyrosine Kinase Links the B Cell Receptor to Nuclear Factor k B Activation
The recognition of antigen by membrane immunoglobulin M (mIgM) results in a complex series of signaling events in the cytoplasm leading to gene activation. Bruton’s tyrosine kinase (BTK), a member of the Tec family of tyrosine kinases, is essential for the full repertoire of IgM signals to be transduced. We examined the ability of BTK to regulate the nuclear factor (NF)k B/Rel family of transcr...
متن کاملRegulation of Bruton tyrosine kinase by the peptidylprolyl isomerase Pin1.
Bruton tyrosine kinase (Btk) is expressed in B-lymphocytes. Mutations in Btk cause X-linked agammaglobulinemia in humans. However, the mechanism of activation and signaling of this enzyme has not been fully investigated. We have here shown that the peptidylprolyl cis/trans isomerase (PPIase) Pin1 is a negative regulator of Btk, controlling its expression level by reducing its half-life, whereas...
