CD8+ T Lymphocyte Subsets in Bladder Tumor Draining Lymph Nodes
Background: Cytotoxic CD8+ T cells, as essential parts of the adaptive immune system, play pivotal roles in anti-tumor immune responses. It is well documented that cytokine expression profiles and activation status of these cells during anti-tumor immune responses affect the outcome of host-tumor interaction. Objective: To investigate the percentages of CD8+ lymphocytes and their subsets in...
متن کاملRegulatory T Cells in Colorectal Cancer
One of the essential protection mechanisms of immune system is Treg cells which play an important role in maintenance ofimmune homeostasis. However, they may also inhibit immune functions against tumor cells. It has been reported that Treg cellsare increased in patients suffering from different types of cancer. Increased number of Treg cells has been shown in tumor lymphnodes, peripheral blood,...
متن کاملIncreased T-regulatory cells in lungs and draining lymph nodes in a murine model of COPD.
The characterisation of regulatory T (Treg) cells in chronic obstructive pulmonary disease (COPD) has become of particular interest considering the recent reports on adaptive immune responses in COPD. More specifically, peribronchial and parenchymal lymphoid follicles (i.e. tertiary lymphoid organs) correlate in number with disease severity in COPD patients [1] and murine models of COPD [2], bu...
متن کاملHigh PD-1 expression on regulatory and effector T-cells in lung cancer draining lymph nodes
The treatment of advanced nonsmall cell lung cancer (NSCLC) with PD-1/PD-L1 immune checkpoint inhibitors has improved clinical outcome for a proportion of patients. The current challenge is to find better biomarkers than PD-L1 immunohistochemistry (IHC) that will identify patients likely to benefit from this therapy. In this exploratory study we assessed the differences in T-cell subsets and PD...
متن کاملRegulatory T-cells and micrometastasis in lymph nodes of stage I NSCLC.
BACKGROUND Regulatory T-cells (Tregs) have a pivotal role not only in abrogating autoimmune disease, but also in tumor immune escape. The purpose of the present study was to evaluate the clinical significance of the relative expression of forkhead/winged helix transcription factor (FOXP3) and micrometastasis in the regional lymph nodes (RLNs) of patients with stage I non-small cell lung cancer ...
