Ancient Viral DNA in Humans Linked to Psychiatric Disorders

Researchers from King's College London have discovered that ancient viral DNA sequences, known as Human Endogenous Retroviruses (HERVs), are expressed in the human brain and contribute to the susceptibility of psychiatric disorders like schizophrenia, bipolar disorder, and depression. This study, published in Nature Communications, highlights the significant role these viral sequences play in brain function and mental health, suggesting that further understanding of HERVs could revolutionize mental health research and treatment.
