Single-cell transcriptomic sequencing identifies the genes related to polyfunctionality of persistent CAR-T cells targeting B7-H3 (CD276) in mice bearing human neuroblastoma xenografts

ABSTRACT: To understand the molecular determinants of B12(VHH)-CAR-T polyfunctionality, we simultaneously measured the protein and RNA expression levels of 95 single CD4+ B12(VHH)-CAR-T cells isolated from IMR5 tumor-bearing mouse and re-stimulated with IMR5 tumor cells in vitro. 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 32 genes that displayed statistically significant, concordant differences between the two cell subsets.

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.

Persistent STAT5 activation reprograms the epigenetic landscape in CD4+ T cells to drive polyfunctionality and antitumor immunity [scRNA-Seq]

Project description:We report here that persistent activation of signal transducer and activator of transcription 5 (STAT5) in tumor-specific CD4+ T cells drives the development of polyfunctional T cells with superior antitumor activities. We showed that ectopic expression of a constitutively active form of murine STAT5A (CASTAT5) in tumor-specific CD4+ T cells established a distinct epigenetic and transcriptional landscape, endowing CD4+ T cells polyfunctionality, exhaustion-resistance and tumor-infiltrating capability. Single cell RNA sequencing analysis (scRNAseq) identified a subset of cells with the molecular signature indicative of their role as progenitor polyfunctional T cells. Importantly, T cells engineered to co-express CD19-targeting chimeric antigen receptors (CD19CAR) and CASTAT5 gave rise to polyfunctional CD4+ CAR T cells capable of providing optimal help to CD8+ T cells to achieve durable and curative outcomes in mice with advanced B-cell lymphoma. Evidence of CASTAT5 functional activities in primary human CD4+ T cells underscores its potential clinical relevance.
