Bcl2L12 plays a critical role in the development of intestinal allergy.

The skewed T helper (Th) 2 response plays a central role in the pathogenesis of allergic diseases, while its initiating factors remain elusive. Recent studies indicate that Bcl2 like protein-12 (Bcl2L12) is associated with the Th2-biased inflammation. This study is designed to test a hypothesis that Bcl2L12 plays a critical role in the initiation of allergic response. In this study, peripheral CD4 T cells were isolated from food allergy (FA) patients and healthy subjects; A mouse FA model was developed to t...

Immune RECIST criteria and symptomatic pseudoprogression in non-small cell lung cancer patients treated with immunotherapy.

Background Uncommon response during immunotherapy is a new challenging issue in oncology practice. Recently, new criteria for evaluation of response to immunotherapy immune response evaluation criteria in solid tumors (iRECIST) were accepted. According to iRECIST, worsening of performance status (PS) accompanied to pseudoprogression reflects most probably the true progression of the malignant disease. Methods A systematic review of the literature was made by using several electronic database with the follow...

The evolving landscape of criteria for evaluating tumor response in the era of cancer immunotherapy: From Karnofsky to iRECIST.

The objective response is an important endpoint to evaluate clinical activity of new anticancer drugs. Standardized criteria for evaluating response are needed for comparing results of different trials and represent the basis for advances in cancer therapy. Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 are the most used in clinical practice and in clinical trials; however, they are not able to capture atypical responses seen with immunotherapy drugs. We describe the evolution of response criteri...

Pancreatic Cancer and Immunotherapy: Resistance Mechanisms and Proposed Solutions.

Pancreatic ductal adenocarcinoma (PDAC) continues to be one of the most aggressive and lethal diseases in the world. The success of immunotherapy in other types of malignancy has led to further trials to understand better the role of immunotherapy in PDAC. However, initial studies with immunotherapy, namely, the checkpoint inhibitors, in PDAC have not been met with the same outcomes. The purpose of this review is to identify and discuss the various resistance mechanisms of PDAC to immunotherapy (pancreatic ...

Junctional adhesion molecules mediate transendothelial migration of dendritic cell vaccine in cancer immunotherapy.

In vitro generated dendritic cells (DCs) have been studied in cancer immunotherapy for decades. However, the detailed molecular mechanism underlying transendothelial migration (TEM) of DC vaccine across the endothelial barrier to regional lymph nodes (LNs) remains largely unknown. Here, we found that junctional adhesion molecule (JAM)-Like (JAML) is involved in the TEM of mouse bone marrow-derived DCs (BMDCs). Treatment with an anti-JAML antibody or JAML knock-down significantly reduced the TEM activity of ...

The next age of immunotherapy: optimisation, stratification and therapeutic synergies.

Association of IL-36γ with tertiary lymphoid structures and inflammatory immune infiltrates in human colorectal cancer.

IL-1 family cytokines play a dual role in the gut, with different family members contributing either protective or pathogenic effects. IL-36γ is an IL-1 family cytokine involved in polarizing type-1 immune responses. However, its function in the gut, including in colorectal cancer pathogenesis, is not well appreciated. In a murine model of colon carcinoma, IL-36γ controls tertiary lymphoid structure formation and promotes a type-1 immune response concurrently with a decrease in expression of immune checkp...

Janus Kinase 1 Plays a Critical Role in Mammary Cancer Progression.

Janus kinases (JAKs) and their downstream STAT proteins play key roles in cytokine signaling, tissue homeostasis, and cancer development. Using a breast cancer model that conditionally lacks Janus kinase 1, we show here that JAK1 is essential for IL-6-class inflammatory cytokine signaling and plays a critical role in metastatic cancer progression. JAK1 is indispensable for the oncogenic activation of STAT1, STAT3, and STAT6 in ERBB2-expressing cancer cells, suggesting that ERBB2 receptor tyrosine kinase com...

Polarity as a physiological modulator of cell function.

Cell polarity, the asymmetric distribution of proteins, organelles, and cytoskeleton, plays an important role in development, homeostasis, and disease. Understanding the mechanisms that govern cell polarity is critical for creating strategies to treat developmental defects, accelerate tissue regeneration, and hinder cancer progression. This review focuses on the role of cell polarity in a number of physiological processes, including asymmetric division, cell migration, immune response mediated by T lymphocy...

Current status of immunotherapy in metastatic colorectal cancer.

Immunotherapy focuses on selectively enhancing the host's immune response against malignant disease. It has been investigated as an important treatment modality against malignant disease for many years, but until recently its use was mostly limited to a few cancers. The advent of new immunemodulating agents in the recent past has changed the landscape for management of many solid tumors. Currently, immunotherapy offers a valuable, and in many cases, a more effective alternate to the conventional cytotoxic t...

The role of gamma delta T lymphocytes in breast cancer: a review.

Gammadelta T (γδT) lymphocytes have provoked interest in oncology, particularly as regards their potential use in immunotherapy, because of their unique ability to recognise antigens without a requirement for major histocompatibility complex antigen presentation, and to quickly activate an anti-tumour response. However, work in some cancers has suggested that they also have pro-tumourigenic activity. Their role in breast cancer is unclear. This review outlines the evidence to date in in vitro studies, in ...

Nitric Oxide Detector Based on WO-1wt%InO-1wt%NbO with State-of-the-Art Selectivity and ppb-Level Sensitivity.

Fast, sensitive, and precise detection of nitric oxide (NO) is critical to many applications in environmental monitoring and early disease diagnosis via respiratory testing. An effective detection system requires a sensor to detect NO gas at the parts per billion (ppb) level, and this system should possess a high degree of anti-interference selectivity. To achieve these targets, a series of gas sensor thin films based on intrinsic WO, one-additive-doped WO (prepared by doping InO or NbO), and two-additive-d...

The role of ErbB3 binding protein 1 in cancer: Friend or foe?

ErbB3, a member of the epidermal growth factor receptor family, reportedly plays an essential role in the regulation of cancer progression and therapeutic resistance. Numerous studies have indicated that ErbB3 binding protein 1 (Ebp1), a binding partner for ErbB3, plays an important regulatory role in the expression and function of ErbB3, but there is no agreement as to whether Ebp1 also has an ErbB3-independent function in cancer and how it might contribute to tumorigenesis. In this review, we will discus...

Mutation load estimation model as a predictor of the response to cancer immunotherapy.

The determination of the mutation load, a total number of nonsynonymous point mutations, by whole-exome sequencing was shown to be useful in predicting the treatment responses to cancer immunotherapy. However, this technique is expensive and time-consuming, which hampers its application in clinical practice. Therefore, the objective of this study was to construct a mutation load estimation model for lung adenocarcinoma, using a small set of genes, as a predictor of the immunotherapy treatment response. Usin...
