Scientists found a mechanism that allows cells to fight off viral DNA – Tech Explorist
Scientists at EPFL have demonstrated the mechanism that allows cells to fight off viral DNA without triggering an immune response against their own genetic material.
Viral infection involves the incorporation of viral DNA into a host cell, replication of that material, and the release of the new viruses. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
When it enters the intracellular fluid, this foreign material triggers a defense mechanism known as the cGAS-STING pathway. The protein cyclic GMP-AMP Synthase (cGAS), which is also found inside the fluid, ties to the invading DNA to make an…
