UT Southwestern Medical Center researchers report that disrupting the light-dark cycle of mice increased their susceptibility to inflammatory disease, indicating that the production of a key immune cell is controlled by the body’s circadian clock.

New research shows that chronic stress changes gene activity in immune cells before they reach the bloodstream. With these changes, the cells are primed to fight an infection or trauma that doesn’t actually exist, leading to an overabundance of the inflammation that is linked to many health problems.

HIV infection is typically treated with antiretroviral therapy, which targets actively replicating HIV but does not affect inactive or latent forms of the virus. The latent reservoir is the biggest barrier to curing HIV, and a study published by Cell Press October 24th in the journal Cell has shown that it could be 60 times larger than previously thought.

Scientists at The Scripps Research Institute (TSRI) have discovered an important process by which special immune cells in the skin help heal wounds. They found that these skin-resident immune cells function as “first responders” to skin injuries in part by producing the molecule known as interleukin-17A (IL-17A), which wards off infection and promotes wound healing.

Scientists have moved closer to developing a universal flu vaccine after using the 2009 pandemic as a natural experiment to study why some people seem to resist severe illness.  Researchers at Imperial College London asked volunteers to donate blood samples just as the swine flu pandemic was getting underway and report any symptoms they experienced over the next two flu seasons.  They found that those who avoided severe illness had more CD8 T cells, a type of virus-killing immune cell, in their blood at the start of the pandemic.

University of Adelaide researchers have made a major discovery that highlights the important role played by immune cells in the risk of developing breast cancer. Researchers have focused their efforts on immune cells known as macrophages in the breast, and how the role of these cells changes because of fluctuations in hormones during different times of the month.
