Roles of Exosomes in Viral Infection | Exosome Diagnostic and Therapeutic in Viral Infections |
---|---|---|---|---|---|
Early endosome development during endocytosis [56, 71] |
mRNA miRNA DNA [12] |
Ads [36] |
Ebola [59] |
Attaches cell surface CAR receptor onto host cells [36] |
Encourages the release of exosomes encompassing the HIV- 1 genome to free the body of viral factors [81] |
ILVs are released from cells produced by the budding of endosomal MVBs [14, 16] |
Tetraspanins (CD9, CD63, CD 81, CD82) [12] |
EBV [98] |
HCV [43] |
Recruits constituents of the host ESCRT mechanism to the sight of viral maturation via Trojan hypothesis [42] |
Targets the HIV-1 genome that have been contrived for effective degradation [81] |
ESCRTs are released to the site of budding [16] |
Immunoregulator molecules (MHCI and MCII) [1] |
HPV [109] |
DENV [1] |
Blocks the development of syngeneic tumor cells vaccinated after immunization [56] |
Used as vaccines against tuberculosis [49] and Toxoplasmosis [42] |
ESCRT I and II stimulate membrane budding [16] |
Cytoskeletal proteins (Actin, Tubulin, Lamin, Myosin) [1] |
Polyoma virus [98] |
HIV [62] |
Support viral reproduction and pathogenesis by facilitating exhaustion of MHC-1 and CD4 particles when Nef proteins are released [77] | Used as analytic indicators in HIV-1 [37] |
ESCRT III completes budding [16] |
Enzymes (Glyceraldehyde 3-phosphate dehydrogenase (GAPDH), 3-phosphoglycerate kinase (PGK), pyruvate kinase (PK), Enolase, ATPase) [1] |
Hepatitis B [110] |
HAV [59] |
Initiate plasmacytoid dendrite cells(pDCs) to release interferon [102] |
Used as a drug delivery tool for systematic or targeted transport to particular tissues or organs [1] |
Exosomes traffic DNA, RNA, lipids, and proteins [111] |
Heat shock proteins (HSP60, HSP70, HSP90) [1] |
HSV [4] |
DENV [60] |
Efficient transport of suppressed membrane protein 1(LMP1) to target cells [12] |
Used as immunomodulators to stimulate or suppress the immune system [56] |
