Researchers have discovered that misreading of therapeutic mRNAs by the cell’s decoding machinery can cause an unintended immune response in the body. They have identified the sequence within the mRNA that causes this to occur and found a way to prevent ‘off-target’ immune responses to enable the safer design of future mRNA therapeutics.

Cambridge scientists have identified a signature in the blood that could help predict how well an individual will respond to vaccines. ̽»¨Ö±²¥discovery, published today in Nature Communications, may explain why, even among vulnerable patient groups, some individuals have better responses to vaccines than others.

̽»¨Ö±²¥protection offered by COVID-19 vaccination declines more rapidly in people with severe obesity than in those with normal weight, scientists at the Universities of Cambridge and Edinburgh have found. ̽»¨Ö±²¥study suggests that people with obesity are likely to need more frequent booster doses to maintain their immunity.

̽»¨Ö±²¥drug remdesivir is likely to be a highly effective antiviral against SARS-CoV-2, according to a new study by a team of UK scientists. Writing in Nature Communications, the researchers describe giving the drug to a patient with COVID-19 and a rare immune disorder, and observing a dramatic improvement in his symptoms and the disappearance of the virus.

Gene editing using ‘molecular scissors’ that snip out and replace faulty DNA could provide an almost unimaginable future for some patients: a complete cure. Cambridge researchers are working towards making the technology cheap and safe, as well as examining the ethical and legal issues surrounding one of the most exciting medical advances of recent times.
