Project description:Study goal is to disclose features of gene expressio profile of non-cancerous liver-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas and tumor-infiltrating lymphocytes of type C hepatitis patients with hepatocellular carcinomas. Keywords: gene expression profile, non-cancerous liver-infiltrating lymphocytes, tumor-infiltrating lymphocytes, type C hepatitis, hepatocellular carcinoma Non-cancerous liver-infiltrating lymphocytes were obtained by laser capture microdissection from surgically resected liver tissues of 12 type C hepatitis patients with hepatocellular carcinoma. The mRNA was amplified and expression profile was comprehensively analyzed with reference RNA using oligo-DNA chip. Tumor-infiltrating lymphocytes were obtained by laser capture microdissection from surgically resected cancer tissues of 12 type C hepatitis patients with hepatocellular carcinoma. The mRNA was amplified and expression profile was comprehensively analyzed with reference RNA using oligo-DNA chip.

Project description:Metastatic uveal melanoma generally responds poorly to immunotherapy. The aim here was to sequence tumor-infiltrating lymphocytes from uveal melanoma metastases to study their phenotypes and T-cell receptor (TCR) clonotypes. We performed paired single-cell transcriptome and TCR sequencing using the 10x Genomics platform of IL2-expanded tumor-infiltrating lymphocytes from 7 liver and 1 subcutaneous metastasis.
Project description:Tumor infiltrating lymphocytes (TILs) play a significant role in the tumor microenvironment in high-grade serous ovarian cancer (HGSOC). To better understand the interactions and functions of TILs in HGSOC progression, we performed proteogenomic profiling of TILs in 65 tumors collected from 12 HGSOC patients.
Project description:We present a novel mathematical model involving various immune cell populations and tumor cellpopulations. The model describes how tumor cells evolve and survive the brief encounter with theimmune system mediated by natural killer (NK) cells and the activated CD8þcytotoxic T lymphocytes(CTLs). The model is composed of ordinary differential equations describing the interactions betweenthese important immune lymphocytes and various tumor cell populations. Based on up-to-dateknowledge of immune evasion and rational considerations, the model is designed to illustrate how tu-mors evade both arms of host immunity (i.e.innate and adaptive immunity). The model predicts that(a) an influx of an external source of NK cells might play a crucial role in enhancing NK-cell immunesurveillance; (b) the host immune system alone is not fully effective against progression of tumor cells;(c) the development of immunoresistance by tumor cells is inevitable in tumor immune surveillance. Ourmodel also supports the importance of infiltrating NK cells in tumor immune surveillance, which can beenhanced by NK cell-based immunotherapeutic approaches.
