Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system -- T cells -- will not be able to react to and fight off serious infections in the body.
Ragweed allergy season can be even more miserable for those with dog, cat or dust mite allergies, according to new research. These year-round allergies appear to "pre-prime" the immune system so symptoms hit harder, according to a study recently published in the Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI).
Being allergic to dogs or cats may worsen your ragweed allergies, according to a study from Queen's University. Researchers found that people with pet allergies often develop ragweed allergy symptoms more quickly than others. But the study also suggests that once allergy season is in full swing, those symptom differences subside.
Working to solve the puzzle of when people develop celiac disease has led researchers from the University of Maryland School of Medicine Center for Celiac Research to some surprising findings. They have found that the autoimmune disorder is on the rise with evidence of increasing cases in the elderly. An epidemiological study published September 27 in the Annals of Medicine supports both trends -- with interesting implications for possible treatment and prevention.
Doctors frequently misuse antibiotics when treating patients hospitalized with respiratory tract infections (RTIs), according to a study to be published in the November issue of Infection Control and Hospital Epidemiology.
A new focus on the immune system's ability to both unleash and restrain its attack on disease has led Dana-Farber Cancer Institute scientists to identify cells in mice that prevent the immune system from attacking the animals' own cells, protecting them from autoimmune diseases such as multiple sclerosis, type 1 diabetes, and lupus.
Research led by the Warwick Medical School at the University of Warwick has found that unhealthy glucose levels in patients with diabetes can cause significantly more problems for the body than just the well-known symptoms of the disease such as kidney damage and circulation problems. The raised glucose can also form what can be described as a sugar coating that can effectively smother and block the mechanisms our bodies use to detect and fight bacterial and fungal infections.
Getting a cold, stomach bug or other infection may lead to increased memory loss in people with Alzheimer's disease, according to research published in the September 8, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology.
A preliminary study by a New Zealand company, Plant & Food Research,* shows that natural chemicals from blackcurrants may help breathing in some types of asthma. Researchers found a compound from a New Zealand blackcurrant may reduce lung inflammation with a multi-action assault in allergy-induced asthma.
Canadian researchers have discovered a new way the body combats respiratory viral infections. In the journal PLoS Pathogens, scientists from the University of Montreal and the University of Montreal Hospital Research Center explain how the NOX2 molecule, an enzyme that...
Researchers at Mount Sinai School of Medicine for the first time have determined that bone marrow cells play a critical role in fighting respiratory viruses, making the bone marrow a potential therapeutic target, especially in people with compromised immune systems.
Treating virulent influenza, sepsis, and other potentially deadly infections long has focused on looking for ways to kill viruses and bacteria. But new research from the University of Utah and Utah State University shows that modulating the body's own overeager inflammatory response to infection may help save more lives.
