New class of ‘dancing’ dendritic cells derived from blood monocytes

The discovery of a new class of dendritic cells that stem from blood monocytes in mice promises to accelerate research into clinical therapies that use these cells, known to be the sentinels of the immune system. Much research has been done on classical dendritic cells, which are found in the lymph tissues of mice. But these are hard to come by in the case of humans. The new technique may allow the generation of “authentic” dendritic cells from human blood samples, however, which could make it much easier to advance dendritic cell-based vaccines and cancer treatments that are under development now.

New HIV vaccine trial first to target dendritic cells

HIV has been able to outmaneuver every vaccine that’s been tried on the virus since it was first discovered in 1981. But no vaccine has yet to directly employ what is arguably the most powerful weapon the human immune system, the dendritic cells that orchestrate the body’s response to infection. Now that’s about to change. Researchers at Rockefeller University, where dendritic cells were discovered in 1973, are building on decades worth of research to launch a novel vaccine trial in hopes of mustering an immune response strong enough to defeat the deadly virus. It’s the first clinical trial of a dendritic cell based vaccine against infection, and researchers hope it will mark a turning point in the battle against AIDS. More »

First evidence that the brain’s native dendritic cells can muster an immune response

Since their initial discovery in 1973, dendritic cells, the sentinels of the immune system, have turned up in a number of places other than the immune organs. They stand guard in the heart, for instance, and in 2008, the first population native to the brain was identified. New research shows that dendritic cells are not only present in the brain, but active, too. They confront foreign substances and seem to form a barrier between healthy and stricken brain tissue following a stroke. More »
