Project description:Tumor-infiltrating (TI)-NK cell numbers predict better than TIL score the efficacy of HER2-targeted antibodies in primary breast cancer patients. To understand the mechanism/s underlying this association, biological processes enriched in NK cell-infiltrated as compared to NK cell-desert HER2-positive breast tumors paired by TIL score were leveraged from transcriptomic data. NK cell-infiltrated tumors were enriched in transcripts regulated by interferons and NF-kB. Among them, levels of CCL5/IFNG-CXCL9/10 positively correlated with the number of TI-NK cells in the original biopsy. Indeed, coordinated expression of CCL5/IFNG-CXCL9/10 transcripts was also evidenced in tumor biopsies from a phase II clinical trial where IFNG levels associated to the achievement of pathological complete response to anti-HER2 antibody treatment (OR 96.3, p=0.01) and correlated with their TI-NK cell score. In in vitro models, anti-HER2 antibody-dependent NK cell activation led to the secretion of CCL5/IFN-ɣ and the subsequent production of IFN-ɣ-dependent CXCL9/10 by bystander breast cancer cells. Ex vivo treatment of breast tumor-derived multicellular cultures with trastuzumab induced the activation of CD16+ TI-NK cells and their conversion into a CD16-CD103+ subpopulation, both endowed with CCL5 and IFN-ɣ producing potential. CD16+ and CD16-CD103+ TI-NK cell subpopulations shared the expression of EOMES, TBX21 and several KIR genes, indicating their lineage relationship; and their proportions positively correlated with total NK cell, CD8+ and tissue-resident T cell frequencies, immune cell subsets with anti-tumor potential. Remarkably, the coordinated induction of CCL5/IFNG-CXCL9/CXCL10 expression, concomitant to the conversion of CD16+ into CD16+/-CD103+ tumor-infiltrating NK cells, was recapitulated in a humanized HER2+ breast cancer in vivo model treated with a combination of anti-HER2 antibodies and in vitro expanded human NK cells, paralleling tumor growth control. Finally, patients achieving good clinical responses to anti-HER2 antibody-based neoadjuvant treatment showed an early and coordinated increase in sera CCL5 and CXCL9/CXCL10 levels which positively correlated with TI-NK cell numbers in the corresponding diagnosis biopsy. Overall, our data point to NK cells as regulators of the tumor microenvironment through the early secretion of CCL5/IFN-ɣ resulting in the production of CXCL9/10 and the recruitment/differentiation of immune infiltrates with anti-tumor potential, ultimately contributing to anti-HER2 antibody clinical efficacy.

Project description:BackgroundThe variability in responses to neoadjuvant treatment with anti-HER2 antibodies prompts to personalized clinical management and the development of innovative treatment strategies. Tumor-infiltrating Natural Killer (TI-NK) cells can predict the efficacy of HER2-targeted antibodies independently from clinicopathological factors in primary HER2-positive breast cancer patients. Understanding the mechanism/s underlying this association would contribute to optimizing patient stratification and provide the rationale for combinatorial approaches with immunotherapy.MethodsWe sought to uncover processes enriched in NK cell-infiltrated tumors as compared to NK cell-desert tumors by microarray analysis. Findings were validated in clinical trial-derived transcriptomic data. In vitro and in vivo preclinical models were used for mechanistic studies. Findings were analysed in clinical samples (tumor and serum) from breast cancer patients.ResultsNK cell-infiltrated tumors were enriched in CCL5/IFNG-CXCL9/10 transcripts. In multivariate logistic regression analysis, IFNG levels underlie the association between TI-NK cells and pathological complete response to neoadjuvant treatment with trastuzumab. Mechanistically, the production of IFN-ɣ by CD16+ NK cells triggered the secretion of CXCL9/10 from cancer cells. This effect was associated to tumor growth control and the conversion of CD16 into CD16-CD103+ NK cells in humanized in vivo models. In human breast tumors, the CD16 and CD103 markers identified lineage-related NK cell subpopulations capable of producing CCL5 and IFN-ɣ, which correlated with tissue-resident CD8+ T cells. Finally, an early increase in serum CCL5/CXCL9 levels identified patients with NK cell-rich tumors showing good responses to anti-HER2 antibody-based neoadjuvant treatment.ConclusionsThis study identifies specialized NK cell subsets as the source of IFN-ɣ influencing the clinical efficacy of anti-HER2 antibodies. It also reveals the potential of serum CCL5/CXCL9 as biomarkers for identifying patients with NK cell-rich tumors and favorable responses to anti-HER2 antibody-based neoadjuvant treatment.

Project description:We investigated the role of chemokines in regulating T-cell accumulation in solid tumors. CCL5 and CXCL9 overexpression was associated with CD8+ T-cell infiltration in common solid tumors. T-cell infiltration required tumor cell-derived CCL5 and was amplified by IFN-dependent, myeloid cell-secreted CXCL9. Accordingly, CCL5-CXCL9 co-expression revealed immunoreactive tumors with prolonged survival and response to checkpoint blockade. Loss of CCL5 expression in human tumors was associated with epigenetic silencing through DNA methylation. Reduction of CCL5 expression caused TIL desertification whereas forced CCL5 expression prevented Cxcl9 and TIL loss and attenuated tumor growth in mice through IFN. The cooperation between tumor-derived CCL5 and IFN-inducible CXCR3 ligands secreted by myeloid cells is key for orchestrating T-cell infiltration in immunoreactive and immunoresponsive tumors.

Project description:Purpose: To investigate the effects of T cell-derived cytokines on gene and protein expression of chemokines in a human RPE cell line (ARPE-19). Methods: We used an in vitro co-culture system in which the RPE and CD3/28-activated T cells were separated by a membrane. Differential gene expression in the RPE cells of chemokine genes was quantified using three different microarrays. Protein expression was determined by single- and multiplex ELISA and immunoblotting. Results: Co-culture with activated T cells increased RPE mRNA and protein expression of chemokines CCL2 (MCP-1), CCL5 (RANTES), CCL7 (MCP-3), CCL8 (MCP-2), CXCL1 (GRO-α), IL8 (CXCL8), CXCL9 (MIG), CXCL10 (IP10), CXCL11 (ITAC), and CX3CL1 (fractalkine). The secretion of CCL7 and CXCL9, 10, and 11 was polarized in the apical direction. Using recombinant human cytokines and neutralizing antibodies we identified IFNgamma and TNFalpha as the two major T cell-derived cytokines responsible for the RPE response. For CCL5, CXCL9, 10, 11, 16, and CX3CL1 we observed a synergistic effect of IFNgamma and TNFalpha in combination. CCL20, CXCL1 and 6, and IL8 were negatively regulated by IFNgamma. Conclusions: RPE cells responded to exposure to T cell-derived cytokines by upregulating expression of several chemokines related to microglial, T cell, and monocyte chemotaxis and activation. This inflammatory stress response may have implications for immune homeostasis in the retina, and for the further understanding of inflammatory ocular diseases such as uveitis and age-related macular degeneration. Differentiated ARPE19 grown on inserts in serum-free media was basolaterally stimulated for 48h with activated T cells or recombinant cytokines (IFNg and/or TNFa) or neutralizing antibodies (aIFNg and/or aTNFa)
