Lymph-node-derived stem-like but not tumor-tissue-resident CD8+ T cells fuel anticancer immunity

Abstract

CD8+ T cell-mediated tumor control and efficacy of immune checkpoint blockade (ICB) are associated with both precursors of exhausted T (TPEX) cells and tissue-resident memory T cells. Their relationships and relative contribution to tumor control, however, are insufficiently understood. Using single-cell RNA sequencing and genetic mouse models, we systematically dissected the heterogeneity and function of cytotoxic T cells in tumors and tumor-draining lymph nodes (tdLNs). We found that intratumoral TCF1+ TPEX cells and their progeny acquired a tissue-residency program that limits their contribution to tumor control and ICB response. By contrast, MYB-dependent stem-like TPEX cells residing in tdLNs sustained CD8+ T cell infiltration into tumors and mediated ICB response. The cytokine TGFβ was the central factor that enforced residency of intratumoral CD8+ T cells and limited the abundance of stem-like TPEX cells in tdLNs, thereby restraining tumor control. A similar network of TGFβ-constrained intratumoral and extratumoral CD8+ T cells with precursor and residency characteristics was found in human cancer.

Extended data

Extended Data Fig. 1 Quantification of TRM-like, TEX and TPEX cells in multiple tumor models.

(a-c) C57BL/6 mice were subcutaneously inoculated with AT3-OVA (n = 5) (a), MC38-OVA (n = 5) (b) or B16-OVA (n = 5) (c) tumor cells and tumors were analyzed when tumors were established. Flow cytometry plots and frequencies of CD44+CD69+ CD103+ TRM-like (left) and PD-1+ TCF1+ or PD-1+TIM-3+ (right) cells within CD44+ CD8+ tumor-infiltrating cells is shown. (d,e) Gating strategy for identification of tumor-infiltrating CD8+ T cells (d) or CD8+ T cells within tdLNs (e) by flow cytometry. Flow cytometry plots are representative. Dots in graphs represent individual mice; horizontal lines and error bars of bar graphs indicate means ± SEM. Data are representative of two independent experiments. P values are from two-tailed unpaired t-tests. P > 0.05, not significant (n.s.).

Extended Data Fig. 2 Single-cell RNA sequencing analysis of CD8 T cells isolated from AT3-OVA tumor bearing mice, and generation and validation of the HobitTomatoCre reporter mouse model.

(a,b) CD44+ CD8+ T cells were sorted from tumors and PD-1+ CD8+ T cells from tdLN of AT3-OVA-tumor-bearing mice and subjected to scRNA sequencing. (a) UMAP analyses showing expression of exhaustion (Tox, Nr4a2), TEX/effector cell (Gzmb, Prf1), TPEX cell (Slamf6) and TRM cell down (Klf2, S1pr1) signature genes. (b) Violin plots showing normalized expression of TRM cell signature44, TGF-β-induced signaling signature45 and Itgae expression within TEX (top) and TPEX (bottom) tumor-specific clusters. (c) Schematic illustrating the generation of the HobitTomatoCre (HobitTomCre) allele. A tdTomato reporter cassette and an IRES followed by a Cre recombinase sequence were inserted downstream of exon5 of the Hobit (Znf683) gene locus (mouse chromosome 4). After translation tdTomato is cleaved from the Hobit protein. (d,e) HobitTomCre P14 T cells were transferred into congenically marked naive recipient mice, which were infected with LCMV Armstrong (n = 3). CD44+CD8+ P14 TRM cells at day 30 post-infection were analyzed. (d) Contour plots (left) and quantification (right) showing Hobit versus CD69 expression of CD44+ P14 T cells in indicated organs. (e) Contour plots (left) and quantification (right) showing Hobit vs CD103 expression of CD44+ P14 T cells in indicated organs. (f) HobitTomCre reporter mice were epicutaneously inoculated with B16-gB tumors for analysis of CD8+ T cells at tumor endpoint. Contour plots of CD103+CD69+ cells in CD44+ CD8+ T cells in indicated organs (upper). Contour plots and quantification of Hobit versus CD103 (middle) and Hobit versus CD69 within the tumor (n = 12), peritumoral skin (n = 14) and tdLN (n = 13).
