Ceramide-1-phosphate: a new mediator of survival and development in retina photoreceptors
(Association For Research In Vision And Ophthalmology, 2011-08)
Purpose. Simple sphingolipids control crucial cellular processes in several cell types. We demonstrated that sphingolipids such as ceramide, sphingosine and sphingosine-1-phosphate are key mediators in the regulation of ...
Análisis experimental de respuesta a la luz en fotorreceptores no convencionales en la retina del embrión de pollo
(2014)
El paradigma clásico de la visión en vertebrados, donde conos y bastones son las únicas células fotorreceptivas presentes en el ojo, ha sido rebatido ante el descubrimiento de células retinales intrínsecamente foto-sensibles ...
A spectroscopy-based methodology for rapid screening and characterization of phytochrome photochemistry in search of Pfr- favoured variants
(Grupo Argentino de Fotobiología, 2020)
Phytochromes are photosensitive proteins with a covalently bound open-chain chromophore that can switch between two principal states: red-light absorbing Pr and far-red light absorbing Pfr. Our group has previously shown ...
Illuminating the inner retina of vertebrates: Nonvisual photopigments with novel functions
(Centro de Estudios sobre Ciencia, Desarrollo y Educacion Superior, 2020-12)
Throughout evolution, the need to detect light has generated highly specialized photoreceptor cells that in vertebrates are mainly located in the retina. The most studied photodetectors within these cells are the visual ...
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
(2015-02)
Sunlight exposure has multiple effect on fruits, as it affects the light climate perceived by fruit photoreceptors and fruit tissue temperature. In grapes (Vitis vinifera L.), light exposure can have a strong effect on ...
Differential UVR8 Signal across the Stem Controls UV-B–Induced Inflorescence Phototropism
(The American Society of Plant Biologists, 2019-09)
In the course of evolution, plants have developed mechanisms that orient their organs toward the incoming light. At the seedling stage, positive phototropism is mainly regulated by phototropin photoreceptors in blue and ...
Bases moleculares de elementos de la cascada de señalización en fotorreceptores microviliares
(2014)
Las opsinas visuales animales han sido agrupadas, basándose en análisis de secuencias, en unas pocas categorías que se relacionan estrechamente con las principales clases morfológicas de fotorreceptores. En particular, ...
Automated detection of photoreceptors in in-vivo retinal images
