Targeting src Homology 2-Containing Inositol Phosphatase-1 (SHIP1)
25 MicroRNAs (miRNAs) are single stranded small RNA molecules that regulate various cellular 26 processes. miR-155 regulates various aspects of innate and adaptive immune response and plays 27 a key role in various viral infections and resulting neuroinflammation. In the present study, 28 evaluated the involvement of miR-155 in modulating Japanese Encephalitis Virus (JEV)29 induced neuroinflamm...
متن کاملDifferential Regulation of B Cell Development, Activation, and Death by the Src Homology 2 Domain–Containing 5′ Inositol Phosphatase (Ship)
Although the Src homology 2 domain-containing 5' inositol phosphatase (SHIP) is a well-known mediator of inhibitory signals after B cell antigen receptor (BCR) coaggregation with the low affinity Fc receptor, it is not known whether SHIP functions to inhibit signals after stimulation through the BCR alone. Here, we show using gene-ablated mice that SHIP is a crucial regulator of BCR-mediated si...
متن کاملA Dual Role for Src Homology 2 Domain–Containing Inositol-5-Phosphatase (Ship) in Immunity
In this report, we demonstrate that the Src homology 2 domain-containing inositol-5-phosphatase (SHIP) plays a critical role in regulating both B cell development and responsiveness to antigen stimulation. SHIP(-/-) mice exhibit a transplantable alteration in B lymphoid development that results in reduced numbers of precursor B (fraction C) and immature B cells in the bone marrow. In vitro, pur...
متن کاملSrc homology 2 domain-containing inositol-5-phosphatase 1 (SHIP1) negatively regulates TLR4-mediated LPS response primarily through a phosphatase activity- and PI-3K-independent mechanism.
Src homology 2 (SH2) domain-containing inositol-5-phosphatase 1 (SHIP1) plays important roles in negatively regulating the activation of immune cells primarily via the phosphoinositide 3-kinase (PI-3K) pathway by catalyzing the PI-3K product PtdIns-3,4,5P3 (phosphatidylinositol-3,4,5-triphosphate) into PtdIns-3,4P2. However, the role of SHIP1 in Toll-like receptor 4 (TLR4)-mediated lipopolysacc...
متن کاملRole of phosphorylase kinase and cyclic AMP-dependent protein kinase in the regulation of phosphorylase phosphatase.
The enzymes of glycogen metabolism are regulated by interconversion between phosphorylated and dephosphorylated forms. In contrast with our well-defined knowledge of the phosphorylation processes of different enzymes and their role in glycogen breakdown and synthesis, the phosphatases catalysing the reverse processes are only now being understood. The regulation of dephosphorylation reactions i...
