Hippo signaling coordinates cellular quiescence with terminal maturation in iNKT cell development and fate decisions [ClariomS]

ABSTRACT: Hippo kinases Mst1 and Mst2 act as molecular rheostats for the terminal maturation and effector differentiation programs of iNKT cells. Loss of Mst1 alone or with Mst2 impedes iNKT cell development, associated with defective IL-15-dependent cell survival

Hippo kinases Mst1 and Mst2 sense and amplify IL-2R−STAT5 signaling in Treg cells to establish stable regulatory activity

Project description:Interleukin-2 (IL-2) and downstream transcription factor STAT5 are important for maintaining regulatory T (Treg) cell homeostasis and function. Tregs can respond to low levels of IL-2, but the mechanisms by which STAT5 is activated during partial IL-2 deficiency remain uncertain. We identified the serine-threonine kinase Mst1 as a signal-dependent amplifier of IL-2−STAT5 activity in Tregs. Tregs had high Mst1 and Mst2 (Mst1−Mst2) activity that was crucial to prevent tumor resistance and autoimmunity. Mechanistically, Mst1−Mst2 sensed IL-2 signals to promote the STAT5 activation necessary for Treg cell homeostasis and lineage stability, and maintain the highly suppressive phophorylated-STAT5+ Treg cell subpopulation. Unbiased quantitative proteomics revealed an association of Mst1 with the cytoskeletal DOCK8−LRCHs module that shaped activity Rho-family GTPase Rac activity, which in turn mediated STAT5 activation in Tregs. Collectively, IL-2−STAT5 signaling critically depends upon Mst1−Mst2 functions to maintain a stable Treg cell pool and immune tolerance. We used microarrays to compare the global transcription profiles of WT and Mst1/Mst2-null Treg cell populations

Microarray of Mst1/2 deleted epithelial cells from E18.5 mouse lungs

Project description:ShhCre;Mst1/2flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from epithelial progenitors during lung morphogenesis. Lungs from E18.5 control and Mst1/2 D/D mice were mechanically and enzymatically dissociated to generate single cell suspension. Epcam(+) cells were isolated using magnetic microbeads. Microarray analysis of mRNAs isolated from Epcam(+) epithelial cells from E18.5 control and Mst1/2 D/D mice was performed to identify transcriptional changes following deletion of the mammalian Hippo kinases (Mst1 and Mst2) from the embryonic lung. The mammalian Hippo kinases, Mst1 and Mst2, were conditionally deleted in epithelial progenitors of the developing lung using ShhCre. Epcam(+) epithelial cells were isolated from the lungs of E18.5 control and Mst1/2 deleted mice. mRNA isolated from Epcam(+) epithelial cells was analyzed by microarray.

RNA-seq analysis of Mst1/2 deleted bronchiolar epithelial cells from adult mouse lungs

Project description:Mst1 and Mst2 were conditionally deleted from non-ciliated bronchiolar epithelial cells in the mature lung. Bronchiolar epithelial cells from control and Mst1/2 deleted mice were isolated by cell sorting and used for RNA-seq analysis. Scgb1a1-rtTA/tetO-Cre/Mst1;2-flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from non-ciliated, secretory bronchiolar epithelial cells. Adult mice were maintained on doxycycline food for 16 days to induce deletion of Mst1/2. Lin-/CD326+/CD24-intermediate cells were isolated by fluorescence cell sorting to enrich for the targeted airway epithelial cells. mRNA isolated from Lin-/CD326+/CD24-intermediate cells from control and Mst1/2 D/D mice was pooled and analyzed by RNA-seq to identify transcriptional changes following deletion of Mst1 and Mst2 from mature lung bronchiolar epithelial cells.
