title: Use of Transgenic Systems to Investigate Oligodendrocyte Differentiation and Function
abstract: Transgenic techniques are generating new strains of animals that are of great importance for many neurological research projects. This includes new animal models of human diseases that should allow analysis of disease etiology and treatment. The insertion of new genetic material into the mouse genome enables the investigator to study the effects of overexpression of normal or mutated genes under a variety of experimental conditions. The use of cell-specific and/or developmentally regulated promoters permits studies on the expression of the specific DNA in selected cells within the nervous system at important developmental stages. This article focuses on the techniques for generating transgenic mice, noting specific advantages or problems that should be considered when designing a transgenic project. The use of reporter genes such as the LacZ gene is discussed, using the particular example of the myelin proteolipid protein promoter directing expression of the LacZ gene in differentiating oligodendrocytes.
