Composition of protozoa-derived exosomes. Proteomic, Biochemical, and Immunological investigations have identified many specific proteins and RNAs present in some exosomes. This is a limited representation of common molecules present within some protozoa-derived exosomes. Molecules illustrated here are grouped based on category function or protein class: Chaperone proteins, Cytoskeletal proteins, Toxins or virulence factors, MVB biogenesis proteins, and RNAs. Some of these molecules are also found in bacteria derived-exosomes (Figure 2) and mammalian derived-exosomes (Figure 1).
