Mapping the hidden rules of a key immune sensor

The immune system depends on molecular alarms that detect danger inside cells. One of these alarms is STING, short for "stimulator of interferon genes." STING helps cells respond to infections, damaged DNA and cancer. When it activates at the right time, it helps protect the body

Geometric neural 'map' may help bilingual brains navigate between languages

Anyone who speaks more than one language knows the feeling of expressing the same thought through entirely different linguistic lenses. A new study by researchers at Rice University and Baylor College of Medicine reveals that the key to this translation ability is a shared geomet

Molecular machinery in cardiac mitochondria reacts to metabolic stress in unexpected way

In a recent study published in Nature Communications, researchers at Karolinska Institutet report that the molecular machinery responsible for cellular energy conversion is more interconnected than previously understood, shedding light on how mitochondria adapt under stress.

Small-molecule antiviral drug targets ACE2 receptor to block coronaviruses from entering c

The ongoing evolution of SARS-CoV-2, particularly the rapid emergence of the omicron variant and its sublineages, has weakened the effectiveness of existing vaccines and antiviral drugs, underscoring the potential risk of future coronavirus pandemics. In response, a joint researc

New Tfr cell model uncovers molecular switches that restrain antibody responses

For the immune system to effectively combat pathogens, antibody responses must be precisely controlled. So-called follicular regulatory T cells (Tfr cells) play a key role in this process by limiting excessive immune responses and helping to maintain immune tolerance. Researchers

Nanotech platform combining paclitaxel with siRNA boosts immune response against lung canc

Researchers at the University of Arizona R. Ken Coit College of Pharmacy have developed a new strategy that helps the immune system recognize and attack lung cancer tumors more effectively. By packaging a chemotherapy drug and an RNA molecule in a tiny lipid carrier, the team boo

Intracellular mechanisms promote tumor survival during hypoxia

Northwestern Medicine scientists have, for the first time, described the underlying mechanisms that regulate how cells rapidly change gene expression in response to hypoxia, a key feature of many treatment-resistant tumors, according to a recent study published in Science Advance
