E-Cadherin is Dispensable to Maintain Langerhans Cells in the Epidermis.

2019

The cell adhesion molecule E-cadherin is a major component of adherens junctions and marks Langerhans cells (LC), the only dendritic cell (DC) population of the epidermis. LC form a dense network and attach themselves to the surrounding keratinocytes via homophilic E-cadherin binding. LC activation, mobilization, and migration require a reduction in LC E-cadherin expression. To determine whether E-cadherin plays a role in regulating LC homeostasis and function, we generated CD11c-specific E-cadherin knockout mice (CD11c-Ecaddel). In the absence of E-cadherin−mediated cell adhesion, LC numbers remained stable and similar as in control mice, even in aged animals. Intriguingly, E-cadherin−defi…

Posttranslational modifications by ADAM10 shape myeloid antigen-presenting cell homeostasis in the splenic marginal zone

2021

The spleen contains phenotypically and functionally distinct conventional dendritic cell (cDC) subpopulations, termed cDC1 and cDC2, which each can be divided into several smaller and less well-characterized subsets. Despite advances in understanding the complexity of cDC ontogeny by transcriptional programming, the significance of posttranslational modifications in controlling tissue-specific cDC subset immunobiology remains elusive. Here, we identified the cell-surface–expressed A-disintegrin-and-metalloproteinase 10 (ADAM10) as an essential regulator of cDC1 and cDC2 homeostasis in the splenic marginal zone (MZ). Mice with a CD11c-specific deletion of ADAM10 (ADAM10(ΔCD11c)) exhibited a …
