A virus that is big enough to be seen under an ordinary light microscope co-opt its host’s systems with the help of ...

For decades, biology textbooks have drawn a firm line: viruses are not alive. They lack the machinery to reproduce on their ...

Viruses have evolved various strategies to coexist and replicate within host cells. Mimicry of host proteins represents a key mechanism that ensures the prolonged persistence of herpesviruses in host ...

Scientists have uncovered a direct molecular mechanism by which gut bacteria inject proteins into human cells, reshaping immune responses and potentially driving inflammatory disease. Scientists have ...
