T-cell ‘training grounds’ behind robust immune system response seen in adenovirus vaccines

Adenovirus vaccine vectors, such as the ChAdOx1 nCov-19 construct which has risen to prominence as a major vaccine for COVID-19, may generate robust long-term immune system responses, according to scientists from the Universities of Oxford and the Cantonal Hospital St.Gallen, Switzerland. Writing in the journal Nature Immunology, they detail an investigation into one […]

Research suggests how tumors become aggressive prostate cancer

The genetic changes that underlie an especially lethal type of prostate cancer have been revealed in a new study by investigators at Weill Cornell Medicine. Learning more about what causes this type of cancer, called neuroendocrine prostate cancer (NEPC), could lead to new approaches for treating it. Most early stage […]

Novel autoantibody adds fuel to COVID-19 “firestorm” of inflammation, blood clots

Researchers at Michigan Medicine have discovered yet another functional autoantibody in COVID-19 patients that contributes to the disease’s development and the “firestorm” of blood clots and inflammation it induces. A growing body of studies suggests COVID-19 emulates many aspects of systemic autoimmune disorders, including the release of a flurry of […]
