Langerhans Cells Regulate Immune Reactions in the Skin
The langerhans cells are marked in red and another cell type are in green. Wild-type mice are on the bottom and have both the red and green cells.

Researchers at Yale School of Medicine have demonstrated that Langerhans cells in the skin, which had been thought to alert the immune system to pathogens, instead dampen the skin’s reaction to infection and inflammation.
