摘要: SHIP-1 is an inositol phosphatase predominantly expressed in hematopoietic cells. Over the ten past years, has been described as important regulator of immune functions. Here, we characterize a new inhibitory function for NOD2 signaling. crucial cytoplasmic bacterial sensor that activates proinflammatory and antimicrobial responses upon invasion. We observed decreases NOD2-induced NF-κB activation macrophages. This negative regulation relies on its interaction with XIAP. Indeed, XIAP essential mediator signaling pathway enables proper Upon activation, C-terminal proline rich domain (PRD) interacts XIAP, thereby disturbing between RIP2 order to decrease
