Epidermal cells in vertebrates and invertebrates ensheath portions of somatosensory neurons via a conserved morphogenetic mechanism, and this ensheathment regulates morphogenesis and function of Drosophila nociceptive neurons.
A combination of transcriptomics, proteomics and modelling identifies a network of interacting protein phosphatases that act as a biological switch to move cells from the stem cell compartment to the differentiated compartment in cultured human epidermis.
Early in mammalian epidermal development, basal epidermal progenitor cells utilize packing and three-dimensional geometry, rather than cortical polarity cues, to inform division orientation and progenitor cell fate.
A protein interaction screen revealed desmosomes as a scaffold for the COP9 de-neddylating complex, to promote epidermal differentiation by governing the balance of Nedd8 and Ubiquitin modifications on Epidermal Growth Factor Receptor.
A method to assess the risk of self-sustained HIV transmission in heterosexuals from phylogenetic and epidemiological data is developed and, when applied to the Swiss HIV epidemic, shows that this risk is negligibly small for Switzerland.
