The human body has been making antivirals for eons, long before scientists did. A protein in your cells called viperin produces molecules that work similarly to the COVID-19 antiviral remdesivir.
Your cells die to keep you alive. Cell death does everything from fighting cancer cells and pathogens to forming your fingers and toes.
The heat and chills that come with fever are not only uncomfortable but also metabolically costly. Increased body temperature, however, can make all the difference when you’re sick.
A potential new Alzheimer’s drug represses the harmful inflammatory response of the brain’s immune cells, reducing disease pathology, preserving neurons, and improving cognition in preclinical tests.
T cells recognize and kill cancer cells but quickly lose their effectiveness. This fast dysfunction may help explain why immunotherapy doesn’t lead to long-term remission for many patients.
MIT researchers characterize gene expression patterns for 22,500 brain vascular cells across 428 donors, revealing insights for Alzheimer’s onset and potential treatments.
