Integrin β3 α2,6-sialylation by the sialyltransferase ST6Gal1 promotes human cytomegalovirus entry into fibroblasts.
Integrin β3 α2,6-sialylation by ST6Gal1 enhances human cytomegalovirus entry into fibroblasts, with a significant reduction observed when this modification is absent.
- Why it matters: Understanding how viral entry mechanisms operate at the molecular level is crucial for developing targeted therapies against HCMV infections, which can cause severe disease in immunocompromised individuals.
- What they did: The study used knockout and knockdown cell models, along with PCR, flow cytometry, and immunofluorescence, to demonstrate that α2,6-sialylation of Integrin β3 is essential for viral internalization and subsequent infection.
- The result: Disruption of α2,6-sialylation impairs viral receptor interactions and signaling pathways, revealing ST6Gal1 and Integrin β3 α2,6-sialylation as promising targets for antiviral strategies.
