Lekha Mikkilineni, James N Kochenderfer
Multiple myeloma (MM) is a nearly always incurable malignancy of plasma cells, so new approaches to treatment are needed. T-cell therapies are a promising approach for treating MM, with a mechanism of action different than those of standard MM treatments. Chimeric antigen receptors (CARs) are fusion proteins incorporating antigen-recognition domains and T-cell signaling domains. T-cells genetically engineered to express CARs can specifically recognize antigens. Success of CAR T-cells against leukemia and lymphoma has encouraged development of CAR T-cell therapies for MM...

BACKGROUND: As the arboviral diseases dengue, chikungunya and Zika emerge in the Americas, so does the need for sustainable vector control policies. To successfully achieve mosquito control, joint efforts of both communities and governments are essential. This study investigates this important, but by-and-large neglected topic. METHODS: In June and July 2015, a cross-sectional mixed methods study applying a survey questionnaire (response rate of 82.5%; n = 339), in-depth interviews (n = 20) and focus group discussions (n = 7; 50 participants) was performed in Curaçao...

Immunotherapy using T cells genetically engineered to express a chimeric antigen receptor (CAR) is rapidly emerging as a promising new treatment for haematological and non-haematological malignancies. CAR-T-cell therapy can induce rapid and durable clinical responses, but is associated with unique acute toxicities, which can be severe or even fatal. Cytokine-release syndrome (CRS), the most commonly observed toxicity, can range in severity from low-grade constitutional symptoms to a high-grade syndrome associated with life-threatening multiorgan dysfunction; rarely, severe CRS can evolve into fulminant haemophagocytic lymphohistiocytosis (HLH)...

Conspicuous consumption refers to the phenomenon where individuals purchase goods for signalling social status, rather than for its inherent functional value. This study (n = 166 male participants) investigated how the outcome of a social competition influenced conspicuous consumption, and its association with competition-induced testosterone reactivity. Winning a competition increased both explicit and implicit preferences for higher-status vs. lower-status products, using both natural stimuli (prestigious cars) and laboratory-tagged stimuli of matched value (university T-shirts)...

Lymphodepletion chemotherapy followed by infusion of CD19-specific chimeric antigen receptor-modified T cells (CAR-T) has produced impressive antitumor responses in patients with refractory CD19(+) B cell malignancies, but is often associated with cytokine release syndrome (CRS). Our understanding of CRS continues to evolve, and identification of the kinetics of CRS and predictive clinical and laboratory biomarkers of severity are needed to evaluate strategies to mitigate toxicity. We report the clinical presentation and identify biomarkers of severe CRS in 133 adult patients who received CD19 CAR-T cells...

Chimeric T cell receptors (CARs) combine extracellular antigen recognition domains and T cell activation components in single molecules. CAR gene transfer thereby allows to generate T cells with engineered specificities. The translational development of CAR-based T cell therapies is most advanced in B cell cancers where CAR-engineered T cells against the B lineage antigen CD19 have generated impressive results in early clinical trials. CARs are now also explored as tools to eliminate autoreactive B cell clones and to engineer T cells with immunosuppressive function for preventing pathological auto- or alloresponses...

Zearalenone (ZEN), one of the most common mycotoxins found in human food and animal feed, has been shown to be effectively detoxified by vitamin C (Vc). The aim of this study was to investigate how vitamin C protects the piglet liver against oxidative stress induced by ZEN. A total of thirty-two healthy female crossbred weaning piglets (Duroc × Landrace × Large white) with an initial weight of 12.27 ± 0.30 kg were randomly divided into four treatment groups of eight piglets per group. The dietary treatments included two zearalenone levels (0 mg kg(-1) and 1...

J subgroup avian leukosis virus (ALV-J) is an exogenous retrovirus of avian. A key feature of ALV-J infection is leading to severe immunosuppressive characteristic of diseases. Viral components of retrovirus were reported closely associated with immunosuppression, and several similarities between exosomes and retrovirus preparations have lead to the hypotheses of retrovirus hijacker exosomes pathway. In this study, we purified exosomes from DF-1 cells infected and uninfected by ALV-J. Electron microscopy and mass spectrometry (MS) analysis showed that ALV-J not only increased the production of exosomes from ALV-J infected DF-1 cells (Exo-J) but also stimulated some proteins expression, especially ALV-J components secreted in exosomes...

PURPOSE: Despite favorable responses of CAR-engineered T cell therapy in patients with hematologic malignancies, the outcome has been far from satisfactory in the treatment of solid tumors, partially owing to the development of an immunosuppressive tumor microenvironment. To overcome this limitation, we engineered CAR-T cells secreting checkpoint inhibitors (CPIs) targeting PD-1 (CAR.αPD1-T) and evaluated their efficacy in a human lung carcinoma xenograft mouse model. EXPERIMENTAL DESIGN: To evaluate the effector function and expansion capacity of CAR...

REVIEW
Huiqin Guo, Kangla Tsung
Tumor reductive therapy is to reduce tumor burden through direct killing of tumor cells. So far, there is no report on the connection between antitumor immunity and tumor reductive therapies. In the last few years, a new category of cancer treatment, immunotherapy, emerged and they are categorized separately from classic cytotoxic treatments (chemo and radiation therapy). The most prominent examples include cellular therapies (LAK and CAR-T) and immune checkpoint inhibitors (anti-PD-1 and CTLA-4). Recent advances in clinical immunotherapy and our understanding of the mechanism behind them revealed that these therapies have a closer relationship with classic cancer treatments than we thought...

New immunotherapy represented by immune checkpoint inhibitor therapy and chimeric antigen receptor T-Cell immunotherapy (CAR-T) has already become hot trend in the treatment of malignant tumors. In gastrointestinal stromal tumor (GIST), with notable tumor-infiltrating immune cells existing in GIST tissues and immunological effects reported in imatinib mesylate (IM) treatment, the clinicians and researchers started to realize the possibilities of immunotherapy in GIST. Recent studies reported that PD-1/PD-L1 or CTLA-4 blockade may enhance the T-cell activity and anti-tumor effect of targeted therapy, which can be applied in advanced GIST, and anti-KIT CAR T-cells indicated a new immunotherapeutic targeted strategy for GIST patients with TKI resistance...

BACKGROUND: CD19-targeted chimeric-antigen receptor-modified T-cells (CAR-T) are promising in the treatment of refractory B-lymphoblastic leukemia (B-ALL). Minimal residual disease (MRD) detection by multicolor flow cytometry (FCM) is critical to distinguish B-ALL MRD from regenerating, non-neoplastic B-cell populations. METHODS: FCM was performed on samples from 9 patients with B-ALL treated with CAR-T. RESULTS: All 9 patients showed response to CAR-T...

Breast cancer is a common malignancy among women. The innate and adaptive immune responses failed to be activated owing to immune modulation in the tumour microenvironment. Decades of scientific study links the overexpression of human epidermal growth factor receptor 2 (ERBB2) antigen with aggressive tumours. The Chimeric Antigen Receptor (CAR) coding for specific tumour-associated antigens could initiate intrinsic T-cell signalling, inducing T-cell activation, and cytotoxic activity without the need for major histocompatibility complex recognition...

The motion of an electron and its spin are generally not coupled. However in a one-dimensional material with strong spin-orbit interaction (SOI) a helical state may emerge at finite magnetic fields, where electrons of opposite spin will have opposite momentum. The existence of this helical state has applications for spin filtering and cooper pair splitter devices and is an essential ingredient for realizing topologically protected quantum computing using Majorana zero modes. Here, we report measurements of a quantum point contact in an indium antimonide nanowire...

REVIEW
Yuan Hu, Zhi-Gang Tian, Cai Zhang
Natural killer (NK) cells are potential effector cells in cell-based cancer immunotherapy, particularly in the control of hematological malignancies. The chimeric antigen receptor (CAR) is an artificially modified fusion protein that consists of an extracellular antigen recognition domain fused to an intracellular signaling domain. T cells genetically modified with a CAR have demonstrated remarkable success in the treatment of hematological cancers. Compared to T cells, CAR-transduced NK cells (CAR-NK) exhibit several advantages, such as safety in clinical use, the mechanisms by which they recognize cancer cells, and their abundance in clinical samples...

Effector T cells equipped with engineered antigen receptors specific for cancer targets have proven to be very efficient. Two methods have emerged: the Chimeric Antigen Receptors (CARs) and T-cell Receptor (TCR) redirection. Although very potent, CAR recognition is limited to membrane antigens which represent around 1% of the total proteins expressed, whereas TCRs have the advantage of targeting any peptide resulting from cellular protein degradation. However, TCRs depend on heavy signalling machinery only present in T cells which restricts the type of eligible therapeutic cells...
