In order to identify novel genes involved in the regulation of the immune system and in the control of inflammatory responses we have initiated a large-scale ENU screen in the mouse. We have established a series of functional screens designed to examine both in-vivo and in-vitro aspects of inflammation and immune responses in all animals in the screen. We have chosen to focus on the identification of recessive mutations, specifically those that have an effect upon function, reasoning that these will yield novel gene products that play a role in disease situations and thus represent therapeutic targets. We are currently screening G3 animals through these assays. We have also developed a backcross strategy and a microsatellite mapping panel to map the mutations. We will present data on our screening strategy, the phenodeviants that have emerged from the program and our plans for genotyping the mice.
