Effect of TCDD Exposure on purified splenic CD8 T cells

Project description:8-12 week, female C57BL/6 mice were injected with 10 µg/kg TCDD or solvent control. CD8+ T cells from spleen were FACS purified and submitted to transcription profiling Keywords: TCDD, AHR, Immunosupression peripheral T cells, CD8 T cells, Toxicogenomics For each group 4 female C57BL/6 mice were treated, spleen surgically removed and single cell suspensions generated. Cell suspensions were pooled, and CD8 positive T cells purified (purity > 99%). RNA was isolated using TRIzol and amplified using the Ambion message AMP kit. Target lableing and hybridization was performed using Affymetrix standard protocols

Human lung CD8+ T cells compared with paired non-naive peripheral blood CD8+ T cells

Project description:It is unknown whether human lung T cells recirculate or belong to a distinct tissue-specific population. This issue is important for understanding their role in protection against viral infection and their contribution to pathophysiology of lung diseases such as chronic obstructive pulmonary disease. By comparing transcriptional profiles of blood and lung CD8+ T cells, we aimed to reveal specific traits of lung CD8+ T cells. A total of 12 samples was analyzed: 10 patient samples (including 1 technical replicate) and 2 reference samples (including 1 technical replicate). Per patient (in total 3 patients), 3 paired samples were analyzed. These samples were non-naive peripheral blood CD8+ T cells (CD45R0+CD3+CD8+ T cells), memory-type lung CD8+ T cells (CD45R0+CD27+CD3+CD8+ T cells) and effector-type lung CD8+ T cells (CD45R0+CD27-CD3+CD8+ T cells). The reference population consisted of a mix of naive peripheral blood CD8+ T cells from 5 healthy donors.

miRNA expression profiles of peripheral monocytes and glioblastoma-infiltrating macrophages

Project description:MicroRNAs (miRNAs) are non-coding molecules involved in post-transcriptional gene regulation that have been shown to modulate tumor cell proliferation and apoptosis and to act as oncogenes or tumor-suppressor genes. Although miRNAs have been linked to tumor progression, the connection between tumor-mediated immune modulation and miRNAs has yet to be explored. Specifically, how the miRNA dysregulation affects the monocyte-derived glioblastoma-infiltrating macrophages, the most abundant immune cell population within the glioblastoma microenvironment, and their immune suppressive properties has not been evaluated to date. Here we managed to purify the glioblastoma-infiltrating macrophages from the tumor microenvironment and compared their miRNA expression profile with the matched peripheral monocytes from the peripheral blood of the same GBM patient as well as with healthy donors. Of note, several most down-regulated miRNA candidates revealed in this study, including miR-142-3p, were also known for their role in mediating tumor-associated immunosuppression. These results suggest a novel approach to identify miRNA immune therapeutics using a two-step process: 1) screen miRNA expression from tumor-associated immune cells relative to normal immune cell, and 2) select and prioritize potential candidates on the basis of binding to immunosuppressive pathways or mechanisms. In the study presented here, 12 samples, including peripheral monocyte samples from 4 healthy donors, peripheral monocytes from 4 GBM patients and matched tumor-infiltrating macrophages extracted from the glioblastoma microenvironment, were used to acquire the miRNA expression profiles of 1732 unique mature miRNA sequences via the Phalanx Human miRNA OneArray Microarray v3 Platform.

RNAseq analysis of PS+ vs PS- non-naive CD8 T cells sorted from peripheral blood of COVID-19 patients

Project description:We report the transcriptional profile of phosphatidylserine (PS) positive and PS negative non-naive peripheral blood CD8 T cells from patients infected with SARS-CoV-2. PS+ CD8 T cells showed increased expression of cell cyclce and cell division associated genes and reduced expression of genes regulating translational initiation, when compared to PS- CD 8 T cells. Furthermore, PS+ CD8 T cells show increased expression of effector T cell genes.

Peripheral Blood CD8+ T-Lymphocyte Immune Response in Benign and Subpopulations of Breast Cancer Patients

Project description:Peripheral blood CD8+ T-lymphocytes play a crucial role in cell-mediated immunity and tumour-related immune responses in breast cancer. The protein profile analysis of CD8+ T-lymphocytes in benign, Luminal A, Luminal B and triple-negative breast cancer (TNBC) patients in comparison to healthy control via a label-free proteomic quantification and gene set enrichment analysis (GSEA) were performed. The results confirmed that the most significantly of RNA degradation signalling pathway was down-regulated in all groups (benign, Luminal A, Luminal B, TNBC) was observed. Given the immunological role that T cells play in the treatment of disease, a better knowledge of RNA metabolism, i.e., the role that mRNA degradation pathways play in human physiology and pathology may lead to novel approaches to the therapeutic use of T cells.

Personalized Neoantigen Cancer Vaccine in Glioblastoma Multiforme

Project description:<p>Neoantigens, which are derived from tumour-specific protein-coding mutations, are exempt from central tolerance, can generate robust immune responses and can function as bona fide antigens that facilitate tumour rejection. We demonstrated that a strategy that uses multi-epitope, personalized neoantigen vaccination, which has previously been tested in patients with high-risk melanoma, is feasible for tumours such as glioblastoma, which typically have a relatively low mutation load and an immunologically ‘cold’ tumour microenvironment. Here we conducted whole-exome sequencing of tumor and normal cells from individual patients with glioblastoma to identify tumor-specific mutations. We assessed the expression of mutated alleles by RNA-sequencing of tumor. We used personalized neoantigen-targeting vaccines to immunize patients newly diagnosed with glioblastoma following surgical resection and conventional radiotherapy in a phase I/Ib study. Patients who did not receive dexamethasone-a highly potent corticosteroid that is frequently prescribed to treat cerebral oedema in patients with glioblastoma-generated circulating polyfunctional neoantigen-specific CD4+ and CD8+ T cell responses that were enriched in a memory phenotype and showed an increase in the number of tumour-infiltrating T cells. Using single-cell T cell receptor analysis, we provide evidence that neoantigen-specific T cells from the peripheral blood can migrate into an intracranial glioblastoma tumour. Neoantigen-targeting vaccines thus have the potential to favourably alter the immune milieu of glioblastoma.</p>
