    Zebrafish have emerged as a powerful model organism for elucidating the development and function of microglia. Generation of new transgenic reporter lines and imaging tools strengthen the zebrafish model in microglia study�in-vivo. The aim is to develop a novel compound transgenic line to study the inflammatory process mediated by NF-kB in microglia cells. This novel compound transgenic line will establish a new model for microglia study. To generate the novel compound zebrafish transgenic model for microglia, we are crossbreeding microglia transgenic line zebrafish (Tg(mpeg1:mCherry) with the NF-kB Tg(6xNFkB:EGFP) transgenic progeny. We first generate a heterozygous F1 progeny which will be bred to generate an F2 homozygous progeny. Once the F1 progeny of the Microglia-NfkB transgenic line is developed, they will be crossbred to develop the Homozygous compound transgenic line. Fluorescent Microscopy will be used to screen the larvae generated from the breeding events. By developing the compound transgenic line, we are optimizing microglia isolation and sorting methodology by using the related antibodies as the marker. The NF-kB microglia transgenic line will provide a unique platform for drug screening to address microglial based ailments, thus furthering the understanding and treatment of human disease.
