Optic genetics

WebHereditary optic neuropathies result from genetic defects that cause vision loss and occasionally cardiac or neurologic abnormalities. There is no effective treatment. Hereditary optic neuropathies include dominant optic atrophy and Leber hereditary optic neuropathy, which are both mitochondrial cytopathies ( 1 ). WebLeber Hereditary Optic Neuropathy (LHON) is the most common inherited mitochondrial disorder and typically affects young males. It typically begins as a unilateral progressive optic neuropathy with sequential involvement of the fellow eye months to years later. Treatment options are limited, but include the use of antioxidant supplements.

Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control … See more In 1979, Francis Crick suggested that controlling all cells of one type in the brain, while leaving the others more or less unaltered, is a real challenge for neuroscience. Francis Crick speculated that a technology using … See more Optogenetics provides millisecond-scale temporal precision which allows the experimenter to keep pace with fast biological information processing (for example, in probing the causal role of specific action potential patterns in defined neurons). Indeed, to … See more Selective expression One of the main problems of optogenetics is that not all the cells in question may express the microbial opsin gene at the same level.
