Neuronal vulnerability in transgenic mice expressing an inducible dominant-negative FGF receptor.

Fibroblast Growth Factors (FGFs) and their receptors (FGFRs) are widely expressed in the mature nervous system and are thought to mediate plasticity and repair. We report the generation of transgenic mice that can be induced to express a dominant-negative FGFR (dnFGFR) in select neuronal populations. We show that a modified Thy1 promoter [Vidal, M.
