Abstract
The nematode Caenorhabditis elegans is a powerful experimental platform for cell biology studies. The molecular mechanisms that mediate cell death and neurodegeneration have been characterized extensively in the nematode. In addition, the availability of a wide arsenal of genetic and molecular tools and methodologies renders C. elegans an organism of choice for modeling human neurodegenerative diseases. Indeed, neuronal necrosis can readily be observed and examined in vivo, in the worm. In this chapter, we describe the two main approaches that are routinely used for monitoring and quantifying neuronal cell death in C. elegans. The first is based on direct visualization of dying cells via Nomarski differential interference contrast (DiC) microscopy, and the second on the assessment of neuronal survival by fluorescence microscopy.
