A new study from the Hebrew University of Jerusalem reveals how viruses that infect bacteria, called bacteriophages or “phages,” use a tiny piece of genetic material to hijack bacterial cells and make more copies of themselves.

The research shows that a very small RNA molecule, called PreS, acts like a hidden “switch” inside the bacterial cell. By flipping this switch, the virus can change how the bacterial cell works and push the infection forward.

An experimental drug developed at Northwestern University has demonstrated further promise as an early intervention for Alzheimer’s disease.

In a new study, Northwestern scientists identified a previously unknown highly toxic sub-species of amyloid beta oligomers - toxic clusters of peptides - that appear to drive several of the brain’s earliest changes, including neuronal dysfunction, inflammation and activation of immune cells.

A study led by researchers at the Germans Trias i Pujol Research Institute (IGTP) shows, in an experimental laboratory model, that delafloxacin inhibits the intracellular replication of Legionella more effectively than one of the current standard treatments. The findings provide new evidence of its potential therapeutic value and support the need for future clinical studies in patients with Legionnaires' disease.

Discovering effective drug combinations may now be easier thanks to a screening platform made public today by St. Jude Children’s Research Hospital scientists. Many diseases, including cancers, require combinations of drugs whose effects are more than the sum of their parts to create effective treatment regimens. However, the number of new drugs and potential combinations has exploded, making classical screening methods impractical.

A study from the University of Maryland, Baltimore County (UMBC), published in Nature Communications, reveals how enteroviruses - including pathogens that cause polio, encephalitis, myocarditis, and the common cold - initiate replication by hijacking host-cell machinery. Led by senior author Deepak Koirala, associate professor of chemistry and biochemistry, and recent Ph.D. graduate Naba Krishna Das, the research fills a knowledge gap on this critical step and could pave the way for a new class of antiviral drugs that are effective against multiple viruses.

From small ions to large molecules, cellular gates control what can pass in and out of cells. But how one such gate, called pannexin-1 (PANX1), can handle vastly different cargo sizes has remained a long-standing mystery.

In a new study, Northwestern University scientists uncovered the molecular trick behind PANX1’s versatility.

A new multi-site study led by researchers at CU Anschutz shows that people with cystic fibrosis (CF) who start the triple-drug therapy elexacaftor/tezacaftor/ivacaftor (ETI) can safely reduce many of their daily lung treatments while maintaining good health for years.

The study was published in the Journal of Cystic Fibrosis.
