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
New virus catalog reveals which pathogens pose the greatest threat
In a typical year, scientists discover two or three viruses that have never been seen in people before. The number fluctuates, but the trend has been fairly steady since the 1960s.
Key gut protein balances immune protection and tolerance
A protein produced by gut immune cells orchestrates both immune protection against pathogens and immune tolerance of gut bacteria, according to a study led by Weill Cornell Medicine investigators. The discovery illuminates the complex biology of the gut immune system and could le
How an emerging class of tick-borne viruses escape human immune defenses
Warmer temperatures bring out ticks that spread diseases such as Lyme disease and Rocky Mountain spotted fever. But another class of emerging tick-borne pathogens—nairoviruses—is on the rise. Some nairoviruses cause high fevers and reduce organ function in people exposed to certa
The broader a fungus's diet, the better it kills insects and helps plants
Many fungi lead triple lives—acting as deadly insect pathogens, decomposers in the soil, and helpful partners living inside and transferring insect-derived nitrogen to plant roots. Scientists have long wondered what allows a single species to pull off these very different roles.
Carbonation, hops and pH: Why safer non-alcoholic beer needs more than bubbles
With careful recipe and process design, non-alcoholic beer can be made more resistant to foodborne pathogens, according to a new study that provides practical guidance on pH, carbonation and hops.
New genomic method to track disease outbreaks globally
Phylo-Plex, a new computational method, has been developed by Wellcome Sanger Institute scientists and their collaborators to allow cost-effective and scalable DNA sequencing of pathogens in laboratories with limited resources. Published today (July 9) in Nature Communications, P
Widely-used method for assessing stream health doesn't work very well
A new study finds a widely used technique for assessing the health of freshwater streams is not effective at detecting a range of water quality problems, including those related to acidity, oxygen levels and the presence of pathogens.
First-of-its-kind computer model tackles antibiotic resistance
Faster and more effective ways to treat Pseudomonas aeruginosa, a bacterium identified by the World Health Organization (WHO) as one of the most life-threatening pathogens, could be possible thanks to a first-of-its-kind 3D computer model developed by the University of Surrey.
