WebbThe processing of cytosolic protein for antigen presentation involves: proteasome-mediated cleavage. transport into phagosomes. displacement of invariant chain. binding … WebbProcessing has two phases: protection and splicing. Protection During this phase, nucleotide sequences are added to each end of the mRNA transcript to protect it from degradation that can occur outside of the nucleus. The 5’ end of a single G nucleotide is attached to the 5’ end of the transcript. This is called the 5’ cap. pin photo to home screen android

Webb12 nov. 2024 · Autophagy is a degradative cellular process that can be both non-selective and selective and begins with the formation of a unique smooth double-membrane phagophore which wraps around a portion of the cytoplasm. Excess and damaged organelles and cytoplasmic protein aggregates are degraded by selective autophagy. … WebbThe collection of these proteins starts to curve the adjacent section of the membrane that eventually pinches off to form an internalized coated vesicle. Clathrin and dynamin then recycle back to the plasma membrane, leaving an uncoated vesicle that is free to fuse with an early endosome.

It is considered to be a stage of antigen presentation pathways. This process involves two distinct pathways for processing of antigens from an organism's own (self) proteins or intracellular pathogens (e.g. viruses), or from phagocytosed pathogens (e.g. bacteria); subsequent presentation of these anti…
