  6. The Cilium

    With the exception of a few types of cells, (acinar cells, T lymphocytes and hepatocytes), every cell in your body has a cilia.  In the vision community, we are used to seeing these structures in the distal portion of the photoreceptors.  The reality is that every cell in the retina has a cilium and some cells […]

  10. Notable Paper: Long-term RNA interference gene therapy in a dominant retinitis pigmentosa mouse model

    Hereditary retinal dystrophies (retinitis pigmentosa, Leber congenital amaurosis, cone-rod dystrophies, macular degeneration) are characterized by loss of visual function, sometimes starting during early childhood, other times in late adulthood.  About 30% of these dystrophies are inherited in an autosomal dominant fashion (RetNet), caused by gain-of-function mutant alleles which encode a malignant form of a normal […]

  11. Proliferative reactive gliosis is compatible with glial metabolic support and neuronal function

    This paper by Vazquez-Chona FR, Swan A, Ferrell WD, Jiang L, Baehr W, Chien WM, Fero M, Marc RE and Levine EM addresses a long standing issue in the field of neuroscience: is the reactive phenotype of glial cells in and of itself detrimental to neural survival or function?

  14. Notable Paper: UNC119 is Required for G Protein Trafficking in Sensory Neurons

      Photoreceptors are specialized cells that elaborate a cilium which becomes the inner and outer segments of the photoreceptor that house photopigments (a beautiful TEM image of a photoreceptor cilium and its inner/outer segment can be seen here)….

  15. Cone Opsin Determines The Time Course of Cone Photoreceptor Degeneration in Leber Congenital Amaurosis

    It is been long known that ventral and central cones degenerate more rapidly than dorsal cones in retinoid-deprived LCA (Leber’s Congenital Amaurosis) models.  This paper in PNAS by Tao Zhang, Wolfgang Baehr…
