The Niessen laboratory aims at understanding how regulation of cell structure determines the shape and function of epithelial barriers. We ask how regulators of cell architecture integrate with signals that control metabolism, inflammation and growth to control the formation and maintenance of the multilayered epidermal skin barrier and how alterations in these biomechanical networks result in disease.

Intercellular adhesion and cell polarity are crucial determinants of tissue morphogenesis and architecture. In contrast to apico-basolateral polarity in simple epithelia, multi-layered epithelia polarizes not within a single cell but across layers. How regulation of cell adhesion and cell shape contributes to the formation and life-long regeneration of multi-layered epithelial barriers, such as the skin epidermal barrier, is only poorly understood. The skin epidermis protects organisms from dehydration and against external challenges such as mechanical insults, UV radiation and micro-organisms. A dysfunctional epidermal barrier is linked to a range of skin diseases.

Using a combination of mouse genetics, high resolution imaging, proteomics and biophysical approaches we address at different scale lengths how regulation of cell shape, cell fate and positioning of cells are coordinated to form, maintain and restore a functional skin epidermal barrier. We also investigate how disturbed coordination of these processes promote barrier dysfuntion and cause diseases such as inflammatory skin diseases as well as skin cancer. 

Ongoing projects in the laboratory are: 
(1) understanding how cell adhesion and cell mechanics regulate epidermal differentiation and barrier formation (2) deciphering the role of polarity signaling in cell division, cell fate, cell mechanics, in epidermal development, homeostasis and skin cancer  (3) address how metabolic pathways, including lipid signaling and insulin/IGF-1 signaling regulate skin barrier function and stem cell dynamics and whether altered metabolic signaling in the skin promotes type II diabetes as well as its associated diseases in the skin.

Our interdisciplinary research profits from fantastic collaborators coming from dermatology, cell biology, mechanobiology, soft matter physics, theoretical physics, chemical engineering, metabolism research, and infectiology.
