Molecules called reactive oxygen species, which include so-called “free radicals,” have long been viewed as damaging byproducts of our body’s metabolism—a reason antioxidant supplements have been considered a potential way to reduce cancer risk.
Bone and joint infections cause significant health problems for patients and lead to millions of dollars in added health costs per year, but clinicians lack reliable tools to predict which patients will develop severe or persistent disease. And when st…
Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and memory r…
Immune cells that normally protect the body from damage by attacking foreign or infected cells are found in the brains of patients with Alzheimer’s disease and related disorders at much higher levels than in healthy brains. The cells appear to contribu…
Researchers at the University of Liverpool helped uncover how the body adapts its immune defenses during periods of increased demand, such as infection, inflammation and recovery following stem cell transplantation.
Naglaa Shoukry and Petronela Ancuta, researchers in the Immunopathology Research Theme at the Centre de recherche du CHUM (CRCHUM), are shedding new light on one of the greatest challenges in HIV research: understanding why the virus remains in the bod…
Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was linked to lower b…
National Institutes of Health (NIH) researchers have discovered rare antibodies that could inform the development of an intervention for alpha-gal syndrome (AGS), an emerging tick bite-associated condition that can lead to allergic reactions to a molec…
Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease that particularly affects young adults. The disease is driven by immune cells—primarily what are known as T lymphocytes. These cells normally fight off pathogens such as viruses, bact…
When a patient is facing certain cancers or an immune condition, clinicians turn to white blood cells for clues about the progression of both diseases and their treatments. From a standard blood draw, a clinical lab isolates peripheral blood mononuclea…
