Unfolded protein response and obesity
WebOne of the typical reactions to these protein secretion stresses is the unfolded protein response (UPR) (Kaufman, 1999). If numerous nascent peptides enter endoplasmic … Web1 Oct 2010 · Unfolded protein response (UPR) is a stress response to increased levels of unfolded proteins in the endoplasmic reticulum (ER). To deal with this stress, all eukaryotic cells share a well-conserved strategy – the upregulation of chaperons and proteases to facilitate protein folding and to degrade the misfolded proteins.

WebObesity leads to the recruitment by adipocytes of macrophages. These macrophages are activated to produce inflammatory cytokines, which blunt insulin signaling. ... THE ADIPOCYTE: DO ENDOPLASMIV RETICULUM STRESS AND THE UNFOLDED PROTEIN RESPONSE PLAY A ROLE? Endoplasmic reticulum stress and the associated unfolded … WebThe interaction between the unfolded protein response (UPR) and autophagy plays either pro-survival or pro-apoptotic roles in the treatment of acute promyelocytic leukemia …
WebUnlike the classic inflammatory response that is activated by pattern-recognition receptors during an infection, the inflammatory response in obesity is initiated by intrinsic signals, such as nutrient sensing, the unfolded protein response, and endoplasmic reticulum stress, and is often referred to as meta-inflammation. 125 These intrinsic ...
