Women’s immune system genes operate differently from men’s
A new technology reveals that immune system genes switch on and off differently in women and men, and the source of that variation is not primarily in the DNA.
Researchers link HIV susceptibility to little-understood immune cell class
High levels of diversity among immune cells called natural killer cells may strongly predispose people to infection by HIV, and may be driven by prior viral exposures, according to a new study.
DNA damage seen in patients undergoing CT scanning
Along with the burgeoning use of advanced medical imaging tests over the past decade have come rising public health concerns about possible links between low-dose radiation and cancer.
Low levels of hormone linked to social deficit in autism
In children with autism, low levels of the hormone vasopressin predict a social deficit that affects their ability to empathize with others.
Juvenile inmates have more mental health hospitalizations, study finds

Iron-containing inflammatory cells seen in Alzheimer’s brains
Using high-field MRI technology and staining techniques, scientists have located inflamed, iron-containing scavenger cells in a memory-formation structure in the brains of Alzheimer’s patients who died.
Team links gene expression, immune system with cancer survival rates
Linking gene expression patterns and immune system response to patient survival rates in nearly 18,000 cases of 39 types of cancers illuminates broad prognostic correlations.
Physicians testified for tobacco companies against plaintiffs with head, neck cancers
A small group of otolaryngologists hired by tobacco companies testified repeatedly that years of heavy smoking did not cause individual cancer cases, a new study reports.
Antioxidants help treat skin-picking disorder in mice, researcher says
Two antioxidant supplements were found to be effective in treating a skin-picking disorder in mice, suggesting they may be useful in people with the condition.
Out-of-pocket health costs tied to antimicrobial resistance
The increasing resistance to antimicrobial drugs is a growing public health concern, particularly in low- and middle-income countries that require high out-of-pocket payments for prescription drugs.
