January 2021 in “bioRxiv (Cold Spring Harbor Laboratory)” The study investigated how skin-resident immune cells, specifically Langerhans cells (LCs) and Dendritic Epidermal T cells (DETCs), coordinate their distribution with epithelial cells during homeostasis in live adult mice. It was found that LCs and DETCs maintain their positions despite the turnover of neighboring basal epithelial stem cells and explore basal epithelial cell junctions through dendritic extensions. Changes in epithelial cell density influenced immune cell density, indicating that epithelial cells determined immune tissue composition. LCs and DETCs were organized in a tiling pattern, which was actively maintained, and when removed, neighboring cells filled the spaces to re-establish this pattern. The GTPase Rac1 was necessary for LCs to maintain their positional stability and tiling pattern. These findings suggested that epidermal cells regulated immune cell density, and immune cells maintained a non-random spatial distribution, enhancing the epidermis's response to environmental challenges.
