Diabetes linked to increased risk of mild cognitive impairment

Individuals with diabetes may have a higher risk of developing mild cognitive impairment, a condition that involves difficulties with thinking and learning and may be an intermediate step toward Alzheimer's disease, according to a report in the April issue of Archives of Neurology, one of the JAMA/Archives journals.

Stress affects levels of serum cytokines across pregnancy

A new study shows that women who report high levels of stress and low social support during pregnancy are more likely to have increased immune system activity, which can trigger inflammatory responses and put them at risk for premature labor and preeclampsia.

Researchers show blood-brain barrier damage could affect multiple sclerosis severity

Immunology researchers at the Kimmel Cancer Center at Jefferson studying a multiple sclerosis (MS)-like disease in mice have shown that the amount of "damage" to the central nervous system's protective blood-brain barrier, in essence, opening it, almost always correlates to the severity of the disease.
