A Genome

Water fleas of the genus Daphnia are among the oldest model systems in biological research. Today, we know more about their natural history and ecology than of any other taxon. The Daphnia model also has left a notable mark on other fields. élie Metchnikoff used Daphnia to test his 1908 Nobel prize–winning idea that macrophages attack invading parasites as part of cellular immunity. August Weismann's studies of water fleas were instrumental in developing his theory that only germ cells transmit heritable information in animals. Richard Woltereck used Daphnia to develop the notion of phenotypic plasticity—that an organism can change its characteristics in response to the environment—an idea that still guides experiments with many organisms that distinguish genetic from environmental effects. With all of these historical achievements, why did the National Institutes of Health (NIH) only recently add Daphnia to its list of model organisms for biomedical research? Moreover, why has Daphnia, at this point in time, become NIH's 13th model system?

The Subject

Lipid nanodomains in cell membranes are believed to play a significant role in a number of critical cellular processes (Elson, et al., 2010). These include, for example, replication processes in enveloped viruses such as bird flu and HIV and signaling mechanisms underlying pathological conditions such as cancer. Due to the potential for developing new disease treatments through the control of these membrane rafts, the biophysics underlying their formation has been the subject of intense study, much of this focused on domain formation in giant unilamellar lipid vesicles (GUVs), a simplified model system.
