Rodent Models of Retinal Degeneration: From Purified Cells in Culture to Living Animals.
Rodent models of retinal degeneration are essential for the development of therapeutic strategies. In addition to living animal models, we here also discuss models based on rodent cell cultures, such as purified retinal ganglion cells and retinal explants. These ex vivo models extend the possibilities for investigating pathological mechanisms and assessing the neuroprotective effect of pharmacological agents by eliminating questions on drug pharmacokinetics and bioavailability. The number of living rodent models has greatly increased with the possibilities to achieve transgenic modifications in animals for knocking in and out genes and mutations. The Cre-lox system has further enabled investigators to target specific genes or mutations in specific cells at specific stages. However, chemically or physically induced models can provide alternatives to such targeted gene modifications. The increased diversity of rodent models has widened our possibility to address most ocular pathologies for providing initial proof of concept of innovative therapeutic strategies.
期刊介绍:
Cold Spring Harbor Perspectives in Medicine is a monthly online publication comprising reviews on different aspects of a variety of diseases, covering everything from the molecular and cellular bases of disease to translational medicine and new therapeutic strategies.
Cold Spring Harbor Perspectives in Medicine is thus unmatched in its depth of coverage and represents an essential source where readers can find informed surveys and critical discussion of advances in molecular medicine.
