Immune system found to tap into chaos theory to regulate itself
The immune system is incredibly complex, but most of us would probably assume that ideally it runs very precisely, like clockwork. However, a new study has found that a big dose of chaos is not just present but may be a necessary piece of the puzzle in helping the immune system regulate itself. Researchers have...

Energizing the immune system to eat cancer
Immune cells called macrophages are supposed to serve and protect, but cancer has found ways to put them to sleep. Now researchers at the Abramson Cancer Center of the University of Pennsylvania say they’ve identified how to fuel macrophages with the energy needed to attack and eat cancer cells. It is well established that macrophages...

Immune system vs. gut bacteria: How vitamin A ‘keeps the peace’
New findings about the role of vitamin A in mediating the relationship between gut bacteria and the immune system may prove “critical” for devising new therapies for autoimmune conditions, such as Crohn’s disease, ulcerative colitis, and other inflammatory diseases that affect the intestine. Carrots, butter, and cheese are some of the richest sources of vitamin A. The gut bacteria are known to play a crucial role...

Chronic fatigue syndrome: New evidence of immune role
Researchers recently investigated the immune system’s role in chronic fatigue system in unprecedented depth. The findings might help design future treatments. Chronic fatigue syndrome (CFS), or myalgic encephalomyelitis (ME), is a mysterious condition. The main symptom of CFS is extreme and often unrelenting fatigue. Others include muscle and joint pain, sleep issues, and flu-like symptoms. Researchers do...

Study implicates hyperactive immune system in aging brain disorders
In a study of fruit flies, NIH scientists suggested that the body’s immune system may play a critical role in the damage caused by aging brain disorders. The results are based on experiments in which the researchers altered the activity of Cdk5, a gene that preclinical studies have suggested is important for early brain development...

FDA approves drug to treat rare immune disease
Gamifant is the first drug to be approved specifically for HLH. The drug’s efficacy was demonstrated in a clinical trial of 27 pediatric patients with suspected or confirmed primary HLH. Patients had refractory, recurrent, or progressive disease while being treated with conventional HLH therapy or were intolerant of conventional HLH therapy. Patients were a mean...
