• Investigating adaptive immune responses in MM patients treated with belantamab mafodotin

  We used single-cell CITE + VDJ sequencing and CapTCRseq to investigate the adaptive immune response, specifically the role of T cells and tumor-reactive gamma delta T cells, in multiple myeloma patients treated with belantamab mafodotin from the on-going Algonquin clinical trial (NCT03715478).

• Single-cell tracking reveals tumor-reactive T cell plasticity during melanoma TIL therapy

  Using 10x genomics 5' Single Cell Immune Profiling kit for single-cell RNA and TCR sequencing, we tracked the transcriptional alterations and fate decisions of tumor-reactive T cells through longitudinal sample obtained from patients undergo-ing TIL therapy. We performed single-cell RNA and single-cell TCR sequencing (scRNA-seq and scTCR-seq) of CD45+ CD3+ tumor-infiltrating lymphocytes from the baseline tumor (pre-ACT), during and after TIL expansion protocol (intermediate product and TIL product, respectively), as well as after cell transfer in blood (PBMC 7dpt) or from metastatic lesions (post-ACT). Samples were derived from patients enrolled in a phase I clinical trial (NCT04165967) that inves-tigated ACT-TIL therapy in combination with nivolumab therapy for metastatic melanoma. Additionally, we established a tumor reactivity assay by co-culturing TIL products with autologous single-cell suspensions of tumor material or short cultured primary melanoma cell lines derived from the tumor material. Reactive T cells were identified by IFNɣ and TNF⍺ expression and sorted to sequence TCRβ genes.

• Single cell RNA and TCR sequencing of adoptive cell transfer using tumor infiltrating lymphocyte.

  This dataset contains two experiments. 1) Single cell RNA and TCR sequencing of tumor infiltrating lymphocites from 7 patients across 5 timepoints: from the baseline tumor (pre-ACT, 7), during and after TIL expansion protocol (intermediate product and TIL product, respectively, 7 each), as well as after cell transfer in blood (PBMC 7dpt, 7) or from metastatic lesions after therapy (post-ACT, 1 patient with one leason and 4 patient with two lesions). Samples were derived from patients with metastatic melanoma which were enrolled in a phase I clinical trial (NCT04165967). The raw reads are available as compressed fastq files. 2) TCRb sequences of the bulk TIL product or TCRb reads derived from an in vitro coculturing assay of TIL product with autologous tumor material and subsequent isolation of IFNɣ and TNF⍺ positive T cells. For some patients multiple autologous tumor material sources could be tested including pre-ACT, post-ACT or tumor lesion derived cell lines. The raw reads are available as compressed fastq files.

• Transcriptomic characterization of breast cancer cells in a luminal-hybrid state

  Background: We have previously identified a subset of early human breast epithelial progenitors that, despite their luminal affiliation, are enriched for basal markers, including CD146 and keratin 14 (K14). This simultaneous presence of both lineages thus defines a luminal-hybrid state. As luminal progenitors are generally proposed as a cell of origin of breast carcinoma, we examined how cells within this luminal hybrid state relate to breast cancer malignancy. Findings: We first analyzed two patient-derived xenograft (PDX)-derived breast cancer cell lines by dividing cell populations based on CD146-expression by FACS and found that this marker defines a cellular state with increased expression of a selection of luminal hybrid markers, including KRT14. When subjecting the sorted cells to in vitro transwell filter analysis, CD146HI/K14HI luminal hybrid state cells were less invasive. Knocking out either CD146- or K14-expression by CRISPR/Cas9 on a CD146/K14-positive background did not affect the in vivo tumorigenic potential, nor the differentiation state. However, when subjecting the respective sorted populations to a soft agar colony formation assay or as in vivo xenografts, CD146HI/K14HI cells exhibited more growth and metastasis, suggesting that the luminal hybrid state contributes to malignant properties. Conclusions: Our findings demonstrate that multiple components of the luminal hybrid state provide distinct properties to tumor malignancy. The fact that breast cancer can reflect a significant part of the original breast gland differentiation hierarchy may add weight to the argument that the search for novel strategies for treating basal-like breast cancer should include manipulation of cellular differentiation states.
