Project description:The goal of the study was to sequence mRNA from tuft cells (identified as CD45-;EpCAM+;IL-25+ using Flare25 reporter mice) in the epithelia of 5 different murine tissues: trachea, thymus, colon, gall baldder, small intestine. As a control, non-tuft epithelial cells (CD45-;EpCAM+;IL-25-) were also isolated. The data were used to identify differentially expressed genes across tuft cells from different tissues and to define a transcriptional tuft cell "signature" that is common to all tissues analyzed but absent in the non-tuft epithelial cells.

Project description:The goal of the study was to sequence mRNA from tuft cells (identified as CD11c-;CD45-;EpCAM+;IL-25+ using Flare25 reporter mice) in C57BL/6 and Aire-/- mice. The data were used to investigate thymic tuft cell heterogeneity with and without AIRE protein expression.

Project description:While the lung bears significant regenerative capacity, severe viral pneumonia can chronically impair lung function by triggering dysplastic remodeling. The connection between these enduring changes and chronic disease remains poorly understood. We recently described the emergence of tuft cells within Krt5+ dysplastic regions after influenza injury. Using bulk and single cell transcriptomics, we characterized and delineated multiple distinct tuft cell populations that arise following influenza clearance. Distinct from intestinal tuft cells which rely on Type 2 immune signals for their expansion, neither IL-25 nor IL-4Ra signaling are required to drive tuft cell development in dysplastic/injured lungs. Furthermore, tuft cells were also observed upon bleomycin injury, suggesting that their development may be a general response to severe lung injury. While intestinal tuft cells promote growth and differentiation of surrounding epithelial cells, in the lungs of tuft cell deficient mice, Krt5+ dysplasia still occurs, goblet cell production is unchanged, and there remains no appreciable contribution of Krt5+ cells into more regionally appropriate alveolar Type 2 cells. Together, these findings highlight unexpected differences in signals necessary for lung tuft cell amplification and establish a framework for future elucidation of tuft cell functions in pulmonary health and disease.

Project description:Rare chemosensory epithelial cells called tuft cells have known roles in small intestinal regulation of type 2 cytokine producing Group 2 innate lymphoid cells. To understand the phenotype of tuft cells in another tissue, the extrahepatic biliary tree, we performed RNAseq analysis on tuft cells and non-tuft epithelial cells from small intestine and gallbladder of the mouse.
