Why do some viruses linger for life? A 900,000-person study maps viral loads
Some viruses that make us sick are cleared by the immune system within days, while others lurk in our bodies for a lifetime and reemerge later to cause new problems. How and why viral levels in the body change over time—and ...

Immune response to cancer may cause autoimmune disorders, including anti-NMDA receptor encephalitis
Consider two seemingly unrelated medical puzzles. First: Every day, our bodies produce hundreds of billions of new cells, many of which are mutated. If cancer arises from cellular mutation, why don't we all have the disease ...
