Аннотация:Neuronal cell death underlies the majority of age‐related human neurodegenerative disorders that culminate with salient and severe cognitive decline affecting patients’ quality of life, identity and eventually leading to death. The identification of disease‐causing genes in familial forms of neurodegenerative diseases enabled the development of genetic models closely replicating pathologies found in human central nervous system. These models dramatically precipitated our understanding of molecular events leading to neuronal death in many neurodegenerative disorders. Today’s large range of cellular and animal models generate rapidly accumulating biochemical and neuropathological data on changes induced by mutated or dysfunctional proteins implicated in neuronal loss. Most of these models are complementary, although all have intrinsic limitations as well as specific advantages. Development of conditional transgenic mouse models in which a deleterious effect of a transgene can be regulated in a controlled way created new possibilities of addressing the basic mechanisms of neurodegeneration and provided a new angle for the development and testing of new therapeutic approaches.
