Researchers have discovered a new mechanism controlling aging in white blood cells. The research, published in the September issue of the Journal of Immunology,...

Celiac Disease Rate Is Growing, Particularly Among Elderly, Study Reveals

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.

Vitamin D Crucial To Activating Immune Defenses

Sleep Deprivation Effect On The Immune System Mirrors Physical Stress

Severe sleep loss jolts the immune system into action, reflecting the same type of immediate response shown during exposure to stress, a new study reports. Researchers in the Netherlands and United Kingdom compared the white blood cell counts of 15 healthy young men under normal and severely sleep-deprived conditions. The greatest changes were seen in the white blood cells known as granulocytes, which showed a loss of day-night rhythmicity, along with increased numbers, particularly at night.

Latest Echinacea Trial Not So Clear Cut, Herbal Experts Say

A recently published clinical trial on Echinacea failed to show a statistically significant benefit for cold symptoms. So what, exactly, did this trial find? "There was a slight trend toward benefit in symptom reduction in both Echinacea groups, with a reduction in duration by about 12 hours, which, although not statistically significant, the authors note may be considered clinically significant by some patients," Blumenthal said.
