Web5 hours ago · MVBs and ISGs are spatially localized apart within beta-cells. The proteins that localize with MVBs are different from the ones that localize with ISGs. Exocytosis of ISGs occurs at the periphery of the beta-cells and takes significantly lesser time when compared to exosome release, which is non-peripheral and takes a longer duration.
Eukaryota, whose members are known as eukaryotes , is a diverse domain of organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains.
