Glucan-Encapsulated siRNA Particles (GeRPs) for Specific Gene Silencing in Kupffer Cells in Mouse Liver

Part of the Methods in Molecular Biology book series (MIMB, volume 2164)


Here, we describe a protocol to prepare and administer glucan-encapsulated RNAi particles (GeRPs), for specific delivery of siRNA and subsequent gene silencing in Kupffer cells (KCs) in mice. This technology is based on baker’s yeast and allows gene manipulation in macrophages in a tissue-specific manner depending on the route of administration and the model that is used. GeRP administered by intravenous injection in mice are delivered to KCs. Therefore, using the GeRP technology to silence genes provides a unique method to study the function of factors expressed by KCs in the regulation of liver function.
