Overview
Overview
From a historical perspective, there is not much information available for retinitis. Although, biotechnology companies have begun to advance development and research on the topic, as ocular technology further develops.
Historical Perspective
Historical Perspective
- 2006: Stem cells: UK Researchers working with mice, transplanted mouse stem cells into mice that had been genetically induced to mimic the human conditions of retinitis pigmentosa and age-related macular degeneration.
- These photoreceptors developed and made the necessary neural connections to the animal’s retinal nerve cells, a key step in the restoration of sight. Previously it was believed that the mature retina has no regenerative ability. This research may in the future lead to using transplants in humans to relieve blindness.[1]
- 2008: Scientists at the Osaka Bioscience Institute have identified a protein, named Pikachurin, which they believe could lead to a treatment for retinitis pigmentosa.[2][3]
- 2008: Retinitis pigmentosa was attempted to be linked to gene expression of FAM46A[4]
- 2010: A possible gene therapy seems to work in mice.[5]
- 2012: Scientists at the Columbia University Medical Center showed on an animal model that gene therapy and induced pluripotent stem cell therapy may be viable options for treating Retinitis Pigmentosa in the future.[6]
- 2012: Scientists at the University of Miami Bascom Palmer Eye Institute presented data showing protection of photoreceptors in an animal model when eyes were injected with mesencephalic astrocyte-derived neurotrophic factor (MANF).[7]
- Researchers at the University of California, Berkeley were able to restore vision to blind mice by exploiting a “photoswitch” that activates retinal ganglion cells in animals with damaged rod and cone cells.[8]
