Animal disease models are non-human animals bearing pathologies that share features with a human disease. Disease models can either exist naturally or be induced artificially and are used for studying human disease with an experimental system.
G protein-coupled receptors are involved in numerous physiological functions, thus, they represent potential pharmaceutical targets. Here Kono et al. describe a new mouse model to image GPCR activation in real-time by exploiting firefly split luciferase fragment complementation that can be detected by bioluminescence imaging.
A recent study identifies a population of CXCR5+ natural killer (NK) cells patrolling B cell follicles in simian immunodeficiency virus (SIV)-infected African green monkeys that might contribute to the lack of disease progression in this nonpathogenic model.
A new mouse model of Rett syndrome, in which MECP2 can be selectively biotinylated, allows for the investigation of cell-specific effects of Rett-causing mutations on gene expression, particularly in female mice.
