Web2 Exosome and extracellular vesicles. PAN et al. discovered exosomes in the 1980s, and after the discovery in the 1990s that B lymphocytes-secreted exosomes could present antigens to activate T-lymphocytes and induce immune responses, exosomes have received widespread attention from scientists. (Pan and Johnstone, 1983; Johnstone et al., 1987). WebProteins needed in the peroxisome have a specific sequence of amino acids called a peroxisomal targeting signal. The classic signal consists of just three amino acids, serine-lysine-leucine, found at the very end (C-terminus) of a protein. This pattern of amino acids is recognized by a helper protein in the cytosol, which brings the protein to ...
