NRF2 is a spatiotemporal metabolic hub driving the polyfunctionality of Th2 cells in allergic asthma

Project description:Polyfunctional T cell responses are detrimental in immune disorders; however, it is unclear how effector T cell subsets acquire polyfunctionality in tissues. Here, we demonstrate that the activation of Nrf2 is necessary for the differentiation polyfunctional Th2 cells in vivo. Reactive oxygen species (ROS) levels are significantly elevated in lung-infiltrating immune cells during allergic asthma, and inhibiting either ROS or Nrf2 significantly decreases eosinophilia and polyfunctional Th2 cells in the lung. In vivo studies using multiple cell-type specific Nrf2-deficient mice and mixed bone marrow chimeras revealed that cell-intrinsic Nrf2 drives IL-5 and IL-13 expression in Th2 cells independently of IL-33. Mechanistically, Nrf2 promotes optimal OXPHOS and glycolysis capacity by inducing PPARg expression and glucose uptake to drive polyfunctionality of Th2 cells. Blocking Nrf2 reduces IL-5 and IL-13 production from house dust mite allergen-specific Th2 cells obtained from asthma patients. These findings demonstrate that Nrf2 acts as a spatiotemporal metabolic hub driving the differentiation of polyfunctional Th2 cells, which may have therapeutic implications for controlling allergic lung inflammation.

NRF2 is a spatiotemporal metabolic hub driving the polyfunctionality of Th2 cells in allergic asthma

Project description:Polyfunctional Th2 cells play a crucial role in triggering diverse pathogenic responses in allergic diseases by producing multiple cytokines. However, the precise mechanism underlying their polyfunctionality remains elusive. In this study, we elucidate the pivotal role of Nrf2 in polyfunctional Th2 cells during allergic asthma. We found that an increase in reactive oxygen species (ROS) in immune cells infiltrating the lungs is necessary for the development of eosinophilic asthma. Deletion of the ROS sensor Nrf2 specifically in T cells, but not in dendritic cells, significantly abolished eosinophilia and polyfunctional Th2 cells in the airway. Mechanistically, Nrf2 intrinsic to T cells is essential for inducing optimal oxidative phosphorylation and glycolysis capacity, thereby driving Th2 cell polyfunctionality, partially by inducing PPARγ, independently of IL-33. Treatment with an Nrf2 inhibitor leads to a substantial decrease in polyfunctional Th2 cells and subsequent eosinophilia in mice, and a reduction in the production of Th2 cytokines from peripheral blood mononuclear cells (PBMCs) in asthmatic patients. These findings highlight the critical role of Nrf2 as a spatial and temporal metabolic hub that is essential for polyfunctional Th2 cells, suggesting potential therapeutic implications for allergic diseases.

High-definition spatiotemporal atlas of cholestatic injury and repair.

Project description:Cholestatic injuries, featured with regional damage around the periportal, cause considerable mortality without curative therapies. It is technically challenging to dissect regional cell-cell interactions and molecular changes to fully understand cholangiopathies. Here, we generated a high-definition atlas of spatiotemporal transcriptome during cholestatic injury and repair. Remarkably, cholangiocytes functioned as a periportal hub by integrating signals from neighboring cells. We also dissected periportal damage, spatial heterogenous reprogramming and zonal regeneration, which appeared to be strongly associated with cholangiocyte. Moreover, spatiotemporal analyses revealed a key inhibitory rheostat for hepatocyte proliferation. Together, our study provides a comprehensive resource that is instrumental to demarcate regional cholestatic injury.

Transgenic expression of survivin compensates for OX40-deficiency in driving Th2 development and allergic inflammation.

Project description:Survivin, an inhibitor of apoptosis family molecule, has been proposed as a crucial intermediate in the signaling pathways leading to T-cell development, proliferation, and expansion. However, the importance of survivin to T-cell-driven inflammatory responses has not been demonstrated. Here, we show that survivin transgenic mice exhibit an increased antigen-driven Th2 lung inflammation and that constitutive expression of survivin reversed the defective lung inflammation even in the absence of OX40 costimulation. We found that OX40-deficient mice were compromised in generating Th2 cells, airway eosinophilia, and IgE responses. In contrast, OX40-deficient/survivin transgenic mice generated normal Th2 responses and exhibited strong lung inflammation. These results suggest that OX40 costimulation crucially engages survivin during antigen-mediated Th2 responses. These findings also promote the notion that OX40 costimulation regulates allergic responses or lung inflammation by targeting survivin thereby enhancing T-cell proliferation and resulting in more differentiated Th2 cells in the allergic inflammatory response.

Th2 single-cell heterogeneity and clonal interorgan distribution in helminth-infected mice

Project description:Th2 cells provide effector functions in type 2 immune responses to helminths and allergens. Despite substantial knowledge about molecular mechanisms of Th2 cell differentiation, there is little information on Th2 cell heterogeneity and clonal distribution between organs mainly due to technical limitations. To address this issue, we performed combined single-cell transcriptome and TCR clonotype analysis on murine Th2 cells in mesenteric lymph nodes (MLN) and lung after infection with Nippostrongylus brasiliensis (Nb) as a model of human hookworm infection. We identified strong organ-specific expression profiles, but also found populations with conserved effector or migration signatures. A substantial MLN subpopulation with an interferon response signature suggests a role for interferon-signaling in Th2 cell differentiation or diversification. RNA-inferred developmental directions further implied proliferation as a hub for differentiation decisions. Although the TCR repertoire appeared to be highly heterogeneous, we identified expanded Th2 clones and CDR3 motifs. Clonal relatedness between distant organs confirmed the effective exchange of Th2 effector cells. However, locally expanded clones dominated the response, as the most expanded clones in MLN and lung did not overlap. This new insight in Th2 cell subsets and clonal relatedness in distant organs demonstrates their heterogeneity and suggests that they serve distinct effector functions.

A single-cell proteomic and transcriptomic assay identifies genes related to polyfunctionality of CAR-T cells targeting GPC1 in pancreatic cancer

Project description:To understand the molecular determinants of CAR-T cell polyfunctionality, we simultaneously measured the protein and RNA expression levels of 23 single CD8+ D4-IgG4H-CD28TM CAR T cells targeting GPC1 stimulated with T3M4 pancreatic cancer cells. We identified two CAR-T clusters, low polyfunctionality and high polyfunctionality subsets, in a 2D t-SNE plot. Moreover, our single-cell mRNA expression profiling revealed 23 genes that displayed statistically significant, concordant differences between the two cell subsets.

The USP7-STAT3-granzyme-Par-1 axis regulates allergic inflammation by promoting differentiation of IL-5-producing Th2 cells

Project description:Uncontrolled type 2 immunity by type 2 helper T (Th2) cells causes intractable allergic diseases; however, whether the interaction of CD4+ T cells shapes the pathophysiology of allergic diseases remains unclear. We identified a subset of Th2 cells that produced the serine proteases granzyme A and B early in differentiation. Granzymes cleave protease-activated receptor (Par)-1 and induce phosphorylation of p38 mitogen-activated protein kinase (MAPK), resulting in the enhanced production of IL-5 and IL-13 in both mouse and human Th2 cells. Ubiquitin-specific protease 7 (USP7) regulates IL-4-induced phosphorylation of STAT3, resulting in granzyme production during Th2 cell differentiation. Genetic deletion of Usp7 or Gzma and pharmacological blockade of granzyme B ameliorated allergic airway inflammation. Furthermore, PAR-1+ and granzyme+ Th2 cells were colocalized in nasal polyps from patients with eosinophilic chronic rhinosinusitis. Thus, the USP7-STAT3-granzymes-Par-1 pathway is a potential therapeutic target for intractable allergic diseases.
