Project description:This dataset comprises TCR-seq data from peripheral blood CD4+ and CD8+ T cells of head and neck squamous cell carcinoma (HNSCC) patients and healthy donors. Viable peripheral blood mononuclear cells (PBMCs) were sorted into CD45+CD3+CD4+ (CD4+ T cells) and CD45+CD3+CD8+ (CD8+ T cells) subsets, and RNA was isolated using the Qiagen AllPrep DNA/RNA Micro kit. TCR libraries were prepared with the SMART-Seq Human TCR-seq with UMIs kit (Takara Bio) and sequenced on an Illumina NovaSeq X Plus platform. This dataset includes samples from 27 tumor patients and five healthy donors (HDs). The study aims to investigate the phenotype, function, and spatial localization of T cells in HNSCC patients. This peripheral blood dataset focuses on characterizing circulating immune determinants of anti-HNSCC immunity and linking circulating T cell clones to those identified in patient-matched tumor scRNA-seq data.
Project description:We compared gene expression profile between healthy-donor peripheral monocytes and glioblastoma-patient peripheral monocytes as well as glioblastoma-patient peripheral monocytes with matched tumor-infiltrating myeloid cells.
Project description:This pilot clinical trial studies low-dose total body irradiation and donor peripheral blood stem cell transplant followed by donor lymphocyte infusion in treatment patients with non-Hodgkin lymphoma, chronic lymphocytic leukemia, or multiple myeloma. Giving total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When healthy stem cells from a donor are infused into the patient they may help the patient’s bone marrow make stem cells, red blood cells, white blood cells, and platelets. Once the donated stem cells begin working, the patient’s immune system may see the remaining cancer cells as not belonging in the patient’s body and destroy them. Giving an infusion of the donor’s white blood cells (donor lymphocyte infusion) may boost this effect.
Project description:This clinical trial studies fludarabine phosphate and total-body radiation followed by donor peripheral blood stem cell transplant and immunosuppression in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient’s immune system from rejecting the donor’s stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient’s bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body’s normal cells. Giving total-body irradiation together with fludarabine phosphate, cyclosporine, and mycophenolate mofetil before transplant may stop this from happening.
Project description:This phase II trial studies giving rituximab before and after a donor peripheral blood stem cell transplant in patients with B-cell lymphoma that does not respond to treatment (refractory) or has come back after a period of improvement (relapsed). Monoclonal antibodies, such as rituximab, can interfere with the ability of cancer cells to grow and spread. Giving rituximab before and after a donor peripheral blood stem cell transplant may help stop cancer from coming back and may help keep the patient’s immune system from rejecting the donor’s stem cells.
Project description:Guillain-Barré syndrome (GBS) is an immune-mediated peripheral neuropathy that debilitates the voluntary and autonomous response of the patient. In this study the transcriptome of peripheral blood mononuclear cells from a GBS patient and her healthy twin were compared to discover possible correlates of disease progression and recovery.
Project description:To track for T cell clones from donor memory T cell fraction infused after abT/CD19-depleted allogenic HSCT we performed TCR beta repertoire sequencing. Patient peripheral blood repertoire was sequenced in two timepoints (p3 and p4: d120-180 and d360-500). Reperotoires for bulk and CD4+ or CD8+ cells from CD45RA-depleted donor apheresis were obtained for most donor-recipient pairs. TCR beta cDNA libraries were prepared using previously published protocol (Zvyagin I.V. et al., Leukemia, 2017). Libraries were sequenced on Illumina NextSeq 500/550 and HiSeq2000/2500 in pair-end mode with read length 100-150 bp. MiGEC software were used for demultiplexing and unique molecular identifier sequence extraction software (https://github.com/mikessh/migec).
