New Discovery Reveals How MX Protein Traps HIV and Herpes Viruses

A group of researchers led by Xavier Saelens and Sven Eyckerman at the VIB-UGent Center for Medical Biotechnology discovered how a protein linked to the human immune system wards off HIV-1 and herpes simplex virus-1 by assembling structures in the cell that lure in these viruses and then trap them or even take them apart.

Harnessing the Power of Beneficial Bacteria to Fight Enterobacteriaceae

Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enterobacteriaceae are a common cause of these infections and have few treatment options. Fecal microbiota transplants have shown promise to curb some of these infections, but their composition varies between batches and they aren't always successful.

Cryo-EM Study Sheds Light on HSV Drug Resistance Mechanisms Through Protein Movement

All organisms -; from fungi to mammals -; have the capacity to evolve and adapt to their environments. But viruses are master shapeshifters with an ability to mutate greater than any other organism. As a result, they can evade treatments or acquire resistance to once-effective antiviral medications.

Discovery of Free-Floating Genes in Bacteria Challenges Genetic Code Assumptions

Since the genetic code was first deciphered in the 1960s, our genes seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why changes in a gene's code affect health.
