• The mucosal tissues of the gut and female reproductive tract (FRT) are susceptible to pathogen infections including bacteria, viruses, and parasites, and are also the targets for immune disorders such as Crohn's disease, inflammatory bowel disease (IBD), and many types of cancers. However, the role of the mucosal immune cells to control these diseases is largely unknown. The limited availability of human mucosal biopsy tissue and the low number of cells that can be isolated from these tissues hampers the characterization of the phenotype and function of human mucosal immune cell subsets. Therefore, human-immune-system humanized mice are surrogate models to investigate the human mucosal immune cell responses during the course of the disease. The current protocols used to harvest the immune cells from the mucosal tissues, however, result in low recovery of cells with poor viability. We have established a novel protocol, which results in a high yield of human lymphocytes with high viability to overcome this issue. The immune cells obtained from a single DRAG mouse by our protocol were sufficient for conducting functional assays and for flow cytometry analyses including phenotypic, exhaustion, and functional panels.
