NASH limits anti-tumour surveillance in immunotherapy-treated HCC

Dominik Pfister, Nicolás Gonzalo Núñez, Roser Pinyol et al. · 2021 · Nature

Abstract Hepatocellular carcinoma (HCC) can have viral or non-viral causes 1–5 . Non-alcoholic steatohepatitis (NASH) is an important driver of HCC. Immunotherapy has been approved for treating HCC, but biomarker-based stratification of patients for optimal response to therapy is an unmet need 6,7 . Here we report the progressive accumulation of exhausted, unconventionally activated CD8 + PD1 + T cells in NASH-affected livers. In preclinical models of NASH-induced HCC, therapeutic immunotherapy targeted at programmed death-1 (PD1) expanded activated CD8 + PD1 + T cells within tumours but did n

Tumor-secreted Pros1 inhibits macrophage M1 polarization to reduce antitumor immune response

Eric Ubil, Laura S. Caskey, Alisha Holtzhausen et al. · 2018 · Journal of Clinical Investigation

Quantifying Neural Oscillatory Synchronization: A Comparison between Spectral Coherence and Phase-Locking Value Approaches

Eric Lowet, Mark Roberts, Pietro Bonizzi et al. · 2016 · PLoS ONE

Synchronization or phase-locking between oscillating neuronal groups is considered to be important for coordination of information among cortical networks. Spectral coherence is a commonly used approach to quantify phase locking between neural signals. We systematically explored the validity of spectral coherence measures for quantifying synchronization among neural oscillators. To that aim, we simulated coupled oscillatory signals that exhibited synchronization dynamics using an abstract phase-oscillator model as well as interacting gamma-generating spiking neural networks. We found that, wit

Oncolytic virus-derived type I interferon restricts CAR T cell therapy

Laura Evgin, Amanda L. Huff, Phonphimon Wongthida et al. · 2020 · Nature Communications

The application of adoptive T cell therapies, including those using chimeric antigen receptor (CAR)-modified T cells, to solid tumors requires combinatorial strategies to overcome immune suppression associated with the tumor microenvironment. Here we test whether the inflammatory nature of oncolytic viruses and their ability to remodel the tumor microenvironment may help to recruit and potentiate the functionality of CAR T cells. Contrary to our hypothesis, VSVmIFNβ infection is associated with attrition of murine EGFRvIII CAR T cells in a B16EGFRvIII model, despite inducing a robust proinflam

Genetic effects influencing risk for major depressive disorder in China and Europe

Tim B. Bigdeli, Stephan Ripke, Roseann E. Peterson et al. · 2017 · Translational Psychiatry

Abstract Major depressive disorder (MDD) is a common, complex psychiatric disorder and a leading cause of disability worldwide. Despite twin studies indicating its modest heritability (~30–40%), extensive heterogeneity and a complex genetic architecture have complicated efforts to detect associated genetic risk variants. We combined single-nucleotide polymorphism (SNP) summary statistics from the CONVERGE and PGC studies of MDD, representing 10 502 Chinese (5282 cases and 5220 controls) and 18 663 European (9447 cases and 9215 controls) subjects. We determined the fraction of SNPs displaying c

DrugEx v3: scaffold-constrained drug design with graph transformer-based reinforcement learning

Xuhan Liu, Kai Ye, Herman van Vlijmen et al. · 2023 · Journal of Cheminformatics

Abstract Rational drug design often starts from specific scaffolds to which side chains/substituents are added or modified due to the large drug-like chemical space available to search for novel drug-like molecules. With the rapid growth of deep learning in drug discovery, a variety of effective approaches have been developed for de novo drug design. In previous work we proposed a method named DrugEx , which can be applied in polypharmacology based on multi-objective deep reinforcement learning. However, the previous version is trained under fixed objectives and does not allow users to input a

Moving beyond anti-amyloid therapy for the prevention and treatment of Alzheimer’s disease

Michael A. Castello, John D. Jeppson, Salvador Soriano · 2014 · BMC Neurology

BACKGROUND: High-profile Phase 3 clinical trials of bapineuzumab and solanezumab, antibodies targeted at amyloid-beta (Aβ) removal, have failed to meet their primary endpoints. Neither drug improves clinical outcomes in patients with late onset AD, joining a long list of unsuccessful attempts to treat AD with anti-amyloid therapies. DISCUSSION: These therapies are based on the assumption that Aβ accumulation is the primary pathogenic trigger of AD. Current evidence suggests that Aβ may actually accumulate as part of an adaptive response to long-term chronic brain stress stimuli that would make

A Model of Loggerhead Sea Turtle (Caretta caretta) Habitat and Movement in the Oceanic North Pacific

Mélanie Abécassis, Inna Senina, Patrick Lehodey et al. · 2013 · PLoS ONE

Habitat preferences for juvenile loggerhead turtles in the North Pacific were investigated with data from two several-year long tagging programs, using 224 satellite transmitters deployed on wild and captive-reared turtles. Animals ranged between 23 and 81 cm in straight carapace length. Tracks were used to investigate changes in temperature preferences and speed of the animals with size. Average sea surface temperatures along the tracks ranged from 18 to 23 °C. Bigger turtles generally experienced larger temperature ranges and were encountered in warmer surface waters. Seasonal differences be

Lack of Protection Against Ebola Virus from Chloroquine in Mice and Hamsters

Darryl Falzarano, David Safronetz, Joseph Prescott et al. · 2015 · Emerging infectious diseases

The antimalarial drug chloroquine has been suggested as a treatment for Ebola virus infection. Chloroquine inhibited virus replication in vitro, but only at cytotoxic concentrations. In mouse and hamster models, treatment did not improve survival. Chloroquine is not a promising treatment for Ebola. Efforts should be directed toward other drug classes.
