Dysregulation of TFH-B-TRM lymphocyte cooperation is associated with unfavorable anti-PD-1 responses in EGFR-mutant lung cancer

ABSTRACT: Patients with non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations exhibit an unfavorable response to PD-1 inhibitor through unclear mechanisms. Hypothesizing that EGFR mutations alter tumor-immune interactions, we compared tumor-infiltrating lymphocytes between EGFR mutant (EGFR-MT) and wild type (EGFR-WT) tumors through single-cell transcriptomic analysis. We found that B cells, CXCL13-producing follicular helper CD4+ T (TFH)-like cells, and tissue-resident memory CD8+ T (TRM)-like cells decreased in EGFR-MT tumors. The NOTCH-RBPJ regulatory network, which is vital for persistence of TRM state, was perturbed, and the interactions between TFH and B cells through the CXCL13-CXCR5 axis disappeared in EGFR-MT tumors. Notably, the proportion of TRM-like cells is predictive for anti-PD-1 response in NSCLC. Our findings suggest that the impairment of TFH-B-TRM cooperation in tertiary lymphoid structure formation, accompanied by the dysregulation of TRM homeostasis and the loss of TFH-B crosstalk, underlies unfavorable anti-PD-1 response in EGFR-MT lung tumors.

Identification of clonal neoantigens derived from driver mutations in an EGFR mutated lung cancer patient benefitting from anti-PD-1

Project description:Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been recommended as the first line therapy for non-small cell lung cancer (NSCLC) with EGFR mutations. However, acquired resistance to EGFR-TKIs is inevitable. Although anti- programmed cell death 1 (PD-1)/PD-ligand (PD-L1) immunotherapies have achieved great clinical success as second-line treatment for many cancer types, the clinical efficacy of anti-PD-1/PD-L1 blockades in EGFR mutated NSCLC patients has been demonstrated to be obviously lower than those without EGFR mutations. Here, we reported an advanced NSCLC patient with exon 19 deletion and T790M EGFR mutation benefitting from anti-PD-1 blockade therapy after acquiring resistance to EGFR-TKI. We characterized the mutational landscape of the patient with next-generation sequencing (NGS), and successfully identified neoantigen-specific T cell clones derived from EGFR exon 19 deletion, TP53 A116T and DENND6B R398Q mutations. Our findings support the potential application of immune checkpoint blockades in NSCLC patients with acquired resistance to EGFR-TKIs in the context of specific clonal neoantigens with high immunogenicity. Personalized immunomodulatory therapy targeting these neoantigens should be explored for better clinical outcomes in EGFR mutant NSCLC patients.

Interferon subverts an AHR-JUN axis to promote CXCL13+ T cells in lupus

Project description:SLE is prototypical autoimmune disease driven by pathologic T cell-B cell interactions. Expansion of B cell-helper T cells including T follicular helper (Tfh) and T peripheral helper (Tph) cells is a prominent feature of systemic lupus erythematosus (SLE). Human Tfh and Tph cells characteristically produce high levels of the B cell chemoattractant CXCL13, yet regulation of T cell CXCL13 production and the relationship between CXCL13+ T cells and other T cell states remains unclear. Here, we identify an imbalance in CD4 T cell phenotypes in SLE patients, with expansion of PD-1+/ICOS+ CXCL13+ T cells and reduction of CD96hi IL-22+ T cells. Using CRISPR screens, we identify the aryl hydrocarbon receptor (AHR) as a potent negative regulator of CXCL13 production by human CD4 T cells. Transcriptomic, epigenetic, and functional studies demonstrate that AHR coordinates with AP-1 family member JUN to prevent CXCL13+ Tph/Tfh cell differentiation and promote an IL-22+ phenotype. Type I interferon (IFN), a pathogenic driver of SLE, opposes AHR and JUN to promote T cell production of CXCL13. These results place CXCL13+ Tph/Tfh cells on a polarization axis opposite from Th22 cells and reveal AHR, JUN, and IFN as key regulators of these divergent T cell states.

Interferon subverts an AHR-JUN axis to promote CXCL13+ T cell in lupus [Time_coure_RNAseq]

Project description:Expansion of B cell-helper T cells including T follicular helper (Tfh) and T peripheral helper (Tph) cells is a prominent feature of systemic lupus erythematosus (SLE), a prototypical autoimmune disease with broad autoantibody production. Human Tfh and Tph cells are marked by high production of the B cell chemoattractant CXCL13, yet regulation of T cell CXCL13 production and the relationship between a CXCL13+ state and other differentiated T cell states remains largely undefined. Here, we identify a dramatic imbalance in CD4 T cell phenotypes in SLE patients, with expansion of PD-1+/ICOS+ CXCL13+ T cells and reduction of CD96hi IL-22+ T cells. Using CRISPR screens, we identify the aryl hydrocarbon receptor (AHR) as a potent negative regulator of CXCL13 production by human CD4 T cells.

CD8+ T cell-1 dependent antitumor response boosted by dual blockade of PD-1 and VGFR2 following EGFR-tyrosine kinase inhibitors against lung cancer with Egfr mutation

Project description:We showed that CD8+ T cell-dependent antitumor response was induced by an EGFR-tyrosine kinase inhibitor (TKI) against syngeneic Egfr-mutant NSCLC tumors and that the effect was further pronounced by the sequential dual blockade of PD-1 and vascular endothelial growth factor receptor 2 (VEGFR2).

Expression data from durvalumab, oleclumab and combo-treated xenograft NSCLC tumors

Project description:Non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations do not respond to anti-PD-1 (L1) as well as tumors without an EGFR mutation. We showed in a xenograft mouse model of EGFR-mutated NSCLC that, neither durvalumab nor oleclumab alone inhibited tumor growth compared to the isotype control. In contrast, the combination of both antibodies significantly inhibited tumor growth and increased gene expressions that corresponded to inflammation and T cell function in tumors treated. We used microarrays to study gene expressions that corresponded to enhanced immune response in antibody-treated mice.
