PI3K-δ and PI3K-γ inhibition by IPI-145 abrogates immune responses and suppresses activity in autoimmune and inflammatory disease models
Chemistry and Biology Nov 13 20, 1364-1374
Phosphoinositide-3 kinases (PI3K) are cell signalling proteins that act as a central node for relaying signals from cell surface receptors and downstream mediators. Specifically they phosphorylate phosphatidylinositol to phosphatidylinositol-3,4,5-trisphosphate (PIP3). This acts a docking site for signalling proteins, leading to the activation of downstream effectors such as BTK. Therefore, inhibition of the PI3K-d and PI3K-? isoforms (PI3K-a and PI3K-ß demonstrated embryonic lethality in murine...
