Although great progress has been made in treatment regimens, gliomas are still incurable and the 5-year survival remains poor. Studies focusing on molecules that regulate tumorigenesis or tumor immunity may provide potential therapeutic strategies for patients with glioma. B7-H6 is selectively expressed in tumor cells and plays vital roles in host immune responses. In this study, we demonstrated that B7-H6 was expressed in glioma cell lines, including CRT, U251, SHG-44, SF-295, TG-905 and U373, and tumor tissues isolated from glioma patients...

Stimulant use may accelerate HIV disease progression through biological and behavioral pathways. However, scant research with treated HIV-positive persons has examined stimulant-associated alterations in pathophysiologic processes relevant to HIV pathogenesis. In a sample of 55 HIV-positive, methamphetamine-using sexual minority men with a viral load less than 200 copies/mL, we conducted RNA sequencing to examine patterns of leukocyte gene expression in participants who had a urine sample that was reactive for stimulants (n = 27) as compared to those who tested non-reactive (n = 28)...

Goat myosin light chain 6 (gMYL6) is a constituent of certain extracted immunization-induced goat anti-cancer bioactive peptides (ACBPs). However, little is known about its activity onto NK cells which are the basic cellular attackers in cancer immunotherapy for patients with malignancies. Because of the complicated extraction process and low yield of gMYL6 out of the goat ACBPs' mixture, the Nano-flow liquid chromatography and C-terminal polycationic tag expression strategy were used to identify and enrich the peptide to investigate its bioactivity against cancers/tumors...

BACKGROUND: Precision medicine and prediction of therapeutic response requires monitoring potential biomarkers before and after treatment. Liquid biopsies provide noninvasive prognostic markers such as circulating tumor DNA and RNA. Circulating tumor RNA (ctRNA) in blood is also used to identify mutations in genes of interest, but additionally, provides information about relative expression levels of important genes. In this study, we analyzed PD-L1 expression in ctRNA isolated from various cancer types...

Check point inhibitor anti-PD1 antibody produced some efficacy in Hepatocellular Carcinoma (HCC) patients previously treated with sorafenib. Unfortunately, HCC patients with hepatitis B virus (HBV) infection did not respond as well as uninfected patients. Previously, SMAC mimetics-the antagonist for inhibitor of apoptosis proteins (IAPs) can rapidly reduce serum hepatitis B virus DNA in animal model. APG-1387 is a novel SMAC-mimetic, small molecule inhibitor targeting inhibitor of apoptosis proteins (IAPs)...

OBJECTIVE: Modeling and analysis of cell population dynamics enhance our understanding of cancer. Here we introduce and explore a new model that may apply to many tissues. ANALYSES: An age-structured model describing coexistence between mutated and ordinary stem cells is developed and explored. The model is transformed into a nonlinear time-delay system governing the dynamics of healthy cells, coupled to a nonlinear differential-difference system describing dynamics of unhealthy cells...

B cell maturation antigen (BCMA) has recently been identified as an important multiple myeloma (MM)-specific target for chimeric antigen receptor (CAR) T cell therapy. In CAR T cell therapy targeting CD19 for lymphoma, host immune anti-murine CAR responses limited the efficacy of repeat dosing and possibly long-term persistence. This clinically relevant concern can be addressed by generating a CAR incorporating a human single-chain variable fragment (scFv). We screened a human B cell-derived scFv phage display library and identified a panel of BCMA-specific clones from which human CARs were engineered...

Allogeneic hematopoietic stem cell transplantation (alloHSCT) produces -similar to the long-established graft-versus-leukemia effect- graft-versus-solid-tumor effects. Clinical trials reported response rates of up to 53%, occurring mostly but not invariably in association with full donor chimerism and/or graft-versus-host disease. Although donor-derived T cells are considered the principal effectors of anti-tumor immunity after alloHSCT or donor leukocyte infusion (DLI), growing evidence indicate that recipient-derived immune cells may also contribute...

Neuroinflammation is a common pathogenic mechanism for a number of neurodegenerative disorders including Alzheimer's and Parkinson's diseases. Microglia, the immune cells of the brain, contribute to the onset and progression of the neuroinflammation observed in these diseases. Microglia become activated and initiate an inflammatory response by interacting with a diverse set of molecules, including the group of endogenous proteins released upon cell damage, termed damage-associated molecular patterns (DAMPs)...

Despite the dramatic antitumor efficiency of certain immune checkpoint inhibitors, immunotherapy has met a bottleneck regarding the response rate and resistance in cancer patients. Increasing evidence indicates that Wnt/β-catenin signaling, one of the best-characterized cancer drivers, promotes cancer progression by regulating the tumor-immune cycle in most of the nodes, including dendritic cells, T cells, and tumor cells. Specifically, abnormal Wnt/β-catenin signaling directly alters a number of regulators critical for the antitumor activities of T cells, especially effector T cells, T helper cells, and regulatory T cells...

In the advent of Immune Checkpoint inhibitors (ICI) and of CAR-T adoptive T-cells, the new frontier in Oncology is Cancer Immunotherapy because of its ability to provide long term clinical benefit in metastatic disease in several solid and liquid tumor types. It is now clear that ICI acts by unmasking preexisting immune responses as well as by inducing de novo responses against tumor neoantigens. Thanks to theprogress made in genomics technologies and the evolution of bioinformatics, neoantigens represent ideal targets, due to their specific expression in cancer tissue and the potential lack of side effects...

Inflammatory bowel disease (IBD) is a disease caused by a dysregulated immune with unknown etiology. Hericium erinaceus (H. erinaceus) is a Chinese medicinal fungus, with the effect of prevention and treatment of gastrointestinal disorders. In this study, we have tested the anti-inflammatory effect of polysaccharide of H. erinaceus (HECP, Mw: 86.67 kDa) in the model of dextran sulfate sodium (DSS)-induced colitis in C57BL/6 mice. Our data indicated that HECP could improve clinical symptoms and down-regulate key markers of oxidative stresses, including nitric oxide (NO), malondialdehyde (MDA), total superoxide dismutase (T-SOD), and myeloperoxidase (MPO)...

The essential roles played by the immune system in the discrimination between self- versus non/altered-self and its integral role in promoting host defense against invading microbes and tumors have been extensively studied for many years. In these contexts, significant advances have been made in defining the molecular and cellular networks that orchestrate cell-cell communication to mediate host defense and pathogen expulsion. Notably, recent studies indicate that in addition to these classical immune functions, cells of the innate and adaptive immune system also sense complex tissue- and environment-derived signals, including those from the nervous system and the diet...

Immune system evasion by cancer cells is one of the hallmarks of cancers, and it occurs with the support of tumor-associated immune cells (TICs) in the tumor microenvironment that increase the growth and invasiveness of tumor cells. With recent advancements in the development of novel near infrared (NIR)-responsive nanoparticles, specifically eradicating TICs or inducing an inflammatory immune response by activating killer T cells has become possible. This review will discuss the mechanisms and applications of photo-triggered immunotherapy in detail...

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immature myeloid progenitor cells that are expanded in cancer and act as potent suppressors of the anti-tumor immune response. MDSCs consist of two major subsets, namely monocytic (M-) MDSCs and granulocytic (G-) MDSCs that differ with respect to their phenotype, morphology and mechanisms of suppression. Here, we cultured bone marrow cells with IL-6 and GM-CSF in vitro to generate a population of bone marrow MDSCs (BM-MDSCs) similar to G-MDSCs from tumor-bearing mice in regards to phenotype, morphology and suppressive-function...

Nucleoside analogs have been frequently identified as antiviral agents. In recent years, gemcitabine, a cytidine analog in clinical use for the treatment of many solid tumors, was also shown to have antiviral activity against a broad range of viruses. Nucleoside analogs generally interfere with cellular nucleos(t)ide synthesis pathways, resulting in the depletion or imbalance of (d)NTP pools. Intriguingly, a few recent reports have shown that some nucleoside analogs, including gemcitabine, activated innate immunity, inducing the expression of interferon-stimulated genes, through nucleos(t)ide synthesis inhibition...

Glioblastoma (GBM) is one of the most deadly brain tumors. The convenient access to The Cancer Genome Atlas (TCGA) database allows for large-scale global gene expression profiling and database mining for potential correlation between genes and overall survival of a variety of malignancies including GBM. Previous reports have shown that tumor microenvironment cells and the extent of infiltrating immune and stromal cells in tumors contribute significantly to prognosis. Immune scores and stromal scores calculated based on the ESTIMATE algorithm could facilitate the quantification of the immune and stromal components in a tumor...

The pro-inflammatory cytokines IL-17 and TNFα are targets for treatment in many chronic inflammatory diseases. Here, we examined their role in liver inflammatory response compared to that of IL-6. Human hepatoma cells (HepaRG, Huh7.5 and HepG2 cells) and primary human hepatocytes (PHH) were cultured with IL-6, IL-17 and/or TNFα. To determine the contribution of the IL-6 pathway in the IL-17/TNFα-mediated effect, an anti-IL-6 receptor antibody was used. IL-17 and TNFα increased in synergy IL-6 secretion by HepaRG cells and PHH but not by Huh7...
