Stem Cell Treatmtent for Retinitis Pigmentosa
Retinitis Pigmentosa treatments using stem cells is now an option...
Retinitis pigmentosa is a group of genetic eye conditions that leads to incurable blindness. In the progression of symptoms for Retinitis pigmentosa, night blindness generally precedes tunnel vision by years or even decades. Many people with Retinitis pigmentosa do not become legally blind until their 40s or 50s and retain some sight all their lives. Others go completely blind from Retinitis pigmentosa, in some cases as early as childhood. Progression of Retinitis pigmentosa is different in each case.
Retinitis pigmentosa is a type of progressive retinal dystrophy, a group of inherited disorders in which abnormalities of the photoreceptors (rods and cones) or the retinal pigment epithelium of the retina lead to progressive visual loss. Affected individuals first experience defective dark adaptation or nyctalopia (night blindness), followed by reduction of the peripheral visual field (known as tunnel vision) and, sometimes, loss of central vision late in the course of the disease.

Related Articles Cell Cycle Proteins and Retinal Degeneration: Evidences of New Potential Therapeutic Targets. Adv Exp Med Biol. 2016;854:371-7 Authors: Arsenijevic Y Abstract During different forms of neurodegenerative diseases, including the retinal degeneration, several cell cycle proteins are expressed in the dying neurons from Drosophila to human revealing that these proteins are a hallmark of neuronal degeneration. This is true for animal models of Alzheimer's, and Parkinson's diseases, Amyotrophic Lateral Sclerosis and for Retinitis Pigmentosa as well as for acute injuries such as stroke and light damage. Longitudinal investigation and loss-of-function studies attest that cell cycle proteins participate to the process of cell death although with different impacts, depending on the disease. In the retina, inhibition of cell cycle protein action can result to massive protection. Nonetheless, the dissection of the molecular mechanisms of neuronal cell death is necessary to develop adapted therapeutic tools to efficiently protect photoreceptors as well as other neuron types.
