Cell Mol Life Sci 2021 Jul 3;78(13):5371-5379. Epub 2021 Jun 3.

Nerve Regeneration Group, IBMC- Instituto de Biologia Molecular e Celular and i3S- Instituto de Investigação e Inovação em Saúde, Universidade do Porto, 4200-135, Porto, Portugal.

The identification of the membrane periodic skeleton (MPS), composed of a periodic lattice of actin rings interconnected by spectrin tetramers, was enabled by the development of super-resolution microscopy, and brought a new exciting perspective to our view of neuronal biology. This exquisite cytoskeleton arrangement plays an important role on mechanisms regulating neuronal (dys)function. The MPS was initially thought to provide mainly for axonal mechanical stability.

Disrupted eye and head development in rainbow trout with reduced ultraviolet (sws1) opsin expression.

J Comp Neurol 2021 08 6;529(11):3013-3031. Epub 2021 Apr 6.

Department of Marine Biosciences, Tokyo University of Marine Science and Technology, Tokyo, Japan.

Visual opsins are proteins expressed by retinal photoreceptors that capture light to begin the process of phototransduction. In vertebrates, the two types of photoreceptors (rods and cones) express one or multiple opsins and are distributed in variable patterns across the retina. Some cones form opsin retinal gradients, as in the mouse, whereas others form more demarcated opsin domains, as in the lattice-like mosaic retinas of teleost fishes. Read More
