concluded that hantaviruses causing HCPS use αvβ3 and αIIβ3 integrins on the cell surface as receptors
Conclusion. B3
-
hantavirus-infected DCs could contribute to virus-associated pathogenesis
Three ways:
- immature DCs transmit virus throughout the body
- infected and matured DCs stimulate T cells, and reach infected organs via bloodstream
- inflammatory cytokines enhances endothelial cell leakage and swelling
-
pro-inflammatory cytokines
A cytokine (protein important for cell signaling) that is released from immune cells and macrophages which causes inflammation.
