Fatty diet activates oldest branch of immune system, causing intestinal tumors

A high-fat-diet-induced immune reaction causes inflammation leading to intestinal cancer in a mouse model — even among animals that are not obese — according to a new study from the Perelman School of..

How ‘hair-of-the-dog’ approach works to treat allergies, mouse study shows

The hair-of-the-dog-that-bit-you is a time-honored allergy remedy for a good reason: It works. A research team led by Duke Health, using mice as the models, has described the cellular processes that ..

Methamphetamine and skin wounds: NYIT researcher wins NIH grant to study immune response

A chance observation in a Southern California fast food restaurant led Luis Martinez, Ph.D., to wonder about the connections behind wound healing problems and methamphetamine use. Martinez, an associ..

Flesh-eating infections in rheumatoid arthritis patients spur new discovery

Rheumatoid arthritis patients taking medications that inhibit interleukin-1beta (IL-1beta), a molecule that stimulates the immune system, are 300 times more likely to experience invasive Group A Strep..

Influenza-neutralizing antibodies generated in human subjects given experimental vaccine

Influenza A viruses are responsible for seasonal disease outbreaks in humans. Influenza A also circulates among bird and some mammal populations and periodically crosses between species. The influenz..

New mechanism activates the immune system against tumor cells

The body’s defences detect and eliminate not only pathogens but also tumour cells. Natural killer cells (NK-Cells) are specifically activated by chemical messengers, the Cytokines, to seek and destroy..

Unlocking secrets of the immune system could help combat colitis

Researchers have unlocked secrets of our ancient immune system, a major scientific advance which could help scientists and clinicians in the global fight against disease. An international team, inclu..
