Webb1 jan. 2024 · This process enables the degradation and turnover of cytoplasmic substrates via membrane-dependent sequestration in autophagic vesicles (autophagosomes) and subsequent lysosomal delivery of cargo. Recent Advances: Selective forms of autophagy can target specific substrates (e.g., organelles, protein aggregates, and lipids) for … Webb3 aug. 2024 · The processed antigen is presented on the cell membrane with MHC-class I molecule which is recognized by CD8 + Tc-cell for degradation. Steps involved in cytosolic pathways are: Proteolytic …
Webb30 nov. 2024 · Cytosolic pH homeostasis is mainly controlled by the following three factors: first, chemical buffering components which comprise bicarbonate, phosphate, protein buffers (e.g., the imidazol group of histidine), etc. [ 9, 10, 11, 12 ]; second, cytosolic H + consumption and H + generation by metabolism [ 5, 8, 13 ]; and third, the direct H + … Webb1 feb. 1999 · To determine how env peptides are generated in the cytosol, we analyzed the processing of two TAP1/2-dependent epitopes containing N-linked glycosylation sites. In each case, processing involved glycosylation-dependent posttranslational modification of asparagine residues to aspartic acid.
Webb12 apr. 2024 · Background: Tocotrienol, a type of vitamin E, is well known for its anti-cancer and other biological activities. This systematic review aims to summarize the involvement of endoplasmic reticulum stress (ERS) and subsequent unfolded protein response (UPR) as the underlying molecular mechanisms for the anticancer properties of tocotrienol. … WebbDengue is the most burdensome vector-borne viral disease in the world. Dengue virus (DENV), the etiological cause of dengue, is transmitted primarily by the Aedes aegypti mosquito. Like any arbovirus, the transmission cycle of dengue involves the complex interactions of a multitude of human and mosquito factors. One point during this …
WebbThe heart is responsible for pumping blood, nutrients, and oxygen from its cavities to the whole body through rhythmic and vigorous contractions. Heart function relies on a delicate balance between continuous energy consumption and generation that changes from birth to adulthood and depends on a very efficient oxidative metabolism and the ability to …
Webb13 apr. 2024 · The mitochondrial unfolded protein response (UPRmt) and mitophagy are two mitochondrial quality control (MQC) systems that work at the molecular and organelle levels, respectively, to maintain mitochondrial homeostasis. Under stress conditions, these two processes are simultaneously activated and compensate for each other when one … incontinence exercise women imagesWebbThe discovery of protein ubiquitination is a fine example of a “bottom to top” discovery and its role in ‘big’ biological processes, e.g. transcription, cell cycle, antigen processing, cellular defense, signalling etc. is now well established (Ciechanover and Iwai 2004; Varshavsky 2005).
