An amphiregulin reporter mouse enables transcriptional and clonal expansion analysis of reparative lung Treg cells

ABSTRACT: Treg cells play critical roles in tissue repair processes, certain of which are mediated by production of the growth factor amphiregulin (Areg). We developed a knock-in mouse model for detection of Areg production in live Treg cells, inserting a Thy1a (Thy1.1) construct into the endogenous Areg locus, such that for every transcript of Areg that is translated, a Thy1.1 transcript is also translated and trafficked separately to the cell surface. We used this mouse model to sort for Thy1.1- or Thy1.1+ (Areg-producing or -non-producing) lung Treg cells in models of lung damage (influenza A virus infection and bleomycin acute lung injury), and used them for assessment of gene expression and clonal expansion of these populations.

Radiation-induced amphiregulin drives tumor metastases

Project description:In this study, we demonstrate that radiation induces the epidermal growth factor receptor (EGFR) ligand amphiregulin (AREG) in tumor cells, which stimulates distant metastasis proliferation in both patients and pre-clinical murine tumor models. Using single-cell RNAseq (sc-RNAseq), we characterized the effects of AREG-induction on immune cells in the lung metastatic microenvironment of B6 mice.

Regulation of the alveolar regenerative niche by amphiregulin-producing Treg cells (10X)

Project description:This study investigates the role of regulatory T cell–derived Areg on lung regeneration following influenza infection. We use single-cell RNA sequencing to capture the heterogeneity of lung mesenchymal populations during influenza infection. Here, we probe the gene expression changes within stromal cells from wildtype mice and in mice that conditionally lack Areg from T cell sources (CD4-cre Areg-flox) at day 8 post infection with PR8/H1N1. n = 1 per genotype.

Regulation of the alveolar regenerative niche by amphiregulin-producing Treg cells (MesSTIM)

Project description:This study investigates the role of regulatory T cell–derived Areg in driving epithelial repair following influenza infection. We use RNA sequencing to probe the gene expression changes within distinct mesenchymal cell subsets of the lung upon stimulation with EGF (50ng/mL), AREG (200ng/mL), or mock. n = 2 wells / group.

Heparan sulfate regulates amphiregulin programming of tissue reparative lung mesenchymal cells during influenza A virus infection in mice

Project description:Amphiregulin is an immune cell-derived growth factor that plays critical roles in tissue repair. After influenza A infection, Treg cells in the lung produce amphiregulin, which signals to a specific Col14a1-expressing subpopulation of lung mesenchymal cells (Col14-LMC) to coordinate their repair activities towards the damaged lung epithelium. Heparan sulfate is a subtype of proteoglycan that can be produced by all cells in the body, and has been implicated in altering growth factor signaling in numerous contexts. Amphiregulin has a heparan sulfate-binding domain; we sought to investigate how the inhibition of heparan sulfate on primary Col14-LMC affects their response to amphiregulin at the transcriptional level.
