Molluscum Virus Carries Human Brain Gene

Researchers report that molluscum contagiosum virus (MCV) contains BC200, a human‑derived noncoding RNA that likely jumped from primates into the virus ~100,000 years ago. The sequence is linked to neuronal translation control and is abnormally expressed in some cancers and Alzheimer’s, and scientists suspect the virus may be using the sequence to manipulate infected skin cells. — Shows that host genes can move into human pathogens with disease‑relevant functions, affecting how we think about viral evolution, disease causation (cancer, neurodegeneration), surveillance and biosecurity policy.
