PW01-001 – Pyrin-PSTPIP1 relation during cell migration
نویسندگان
چکیده
Introduction MEFV (MEditerranien FeVer) gene mutations cause Familial Mediterranean Fever (FMF). This gene encodes a protein termed as Pyrin, which appears to play an important role in the inflammatory pathways. It is far characterized that Pyrin, which is expressed in neutrophils, interacts with PSTPIP1 and actin proteins. In previous studies PSTPIP1 has been shown to interact with cell migration proteins and actin polymerization is a main force driving neutrophil migration. Therefore, we hypothesized that Pyrin can play role in cell migration through the interaction with actin and PSTPIP1.

Pyrin Modulates the Intracellular Distribution of PSTPIP1
PSTPIP1 is a cytoskeleton-associated adaptor protein that links PEST-type phosphatases to their substrates. Mutations in PSTPIP1 cause PAPA syndrome (Pyogenic sterile Arthritis, Pyoderma gangrenosum, and Acne), an autoinflammatory disease. PSTPIP1 binds to pyrin and mutations in pyrin result in familial Mediterranean fever (FMF), a related autoinflammatory disorder. Since disease-associated mut...
متن کاملPyrin binds the PSTPIP1/CD2BP1 protein, defining familial Mediterranean fever and PAPA syndrome as disorders in the same pathway.
Pyrin, the familial Mediterranean fever protein, is found in association with the cytoskeleton in myeloid/monocytic cells and modulates IL-1beta processing, NF-kappaB activation, and apoptosis. These effects are mediated in part through cognate interactions with the adaptor protein ASC, which shares an N-terminal motif with pyrin. We sought additional upstream regulators of inflammation by usin...

Introduction MEFV which encodes pyrin, cause familial Mediterranean fever (FMF), the most common auto-inflammatory disease. The pyrin protein appears to be a regulator of inflammation, but its exact role on inflammatory pathways is still controversial. Several pyrin-interacting proteins have been identified, each of which are related to inflammation through regulation of cell death, cytokine se...
متن کاملInvestigation of the inflammatory cell migration process in familial Mediterranean fever
Introduction Familial Mediterranean fever (FMF) is one of the most common autoinflammatory disorders and is characterized by episodic attacks of fever, along with inflammation. FMF pathogenesis is associated with various mutations in the MEFV gene, which encodes pyrin. Pyrin is expressed predominantly in neutrophils that have an important role in the innate immune response. Several proteins rel...

Introduction Mutations M680I, M694V and V726A of Pyrin the product of MEFV gene are localized at the domain B30.2 (PB30.2D) and responsible for manifestation of the most widespread and severe forms of FMF. From the other hand, it is well known that malfunction of the pyrin-caspase-1complex is the main reason for inflammation during FMF. Therefore, we suggest that comparative investigation of no...
