Cytokine storms in COVID-19 patients may prevent the development of long-term immunity

Shiv Pillai, MD, Ph.D., investigator in the Ragon Institute of MGH, MIT and Harvard and professor at Harvard Medical School (HMS), recently published a paper in Cell showing that that high levels of some cytokines seen in COVID-19 patients, as part of a cytokine storm, may prevent the development of long-term immunity to SARS-CoV-2, the virus that causes COVID-19.

Researchers study how bacteria adapt to their host cells

In the environment, they are often found inside unicellular organisms. A research team led by Matthias Horn at the Centre for Microbiology and Environmental Systems Science at the University of Vienna has made use of laboratory experiments to gain a better understanding of how these bacteria adapt to their host cell over time.

Drugs designed to lower alpha-ketoglutarate levels could help fight DIPG tumors

Every year, 150 to 300 children in the United States are diagnosed with diffuse intrinsic pontine gliomas (DIPGs), aggressive and lethal tumors that grow deep inside the brain, for which there are no cures.

'Survival of the fittest': How meiotic drivers shape the evolution of gamete formation

It can be hard to dispute the common adage 'survival of the fittest'. After all, "most of the genes in the genome are there because they're doing something good," says Sarah Zanders, PhD, assistant investigator at the Stowers Institute for Medical Research

Study shows how proteins act as a defense mechanism to protect their own DNA

Viruses usually inject their DNA into a host cell to multiply. As soon as this foreign material penetrates the intracellular fluid, it activates a defense mechanism called the cGAS-STING pathway.
