Targeting T cell exhaustion: emerging strategies in non-small cell lung cancer.

Lung cancer continues to be a major contributor to cancer-related deaths globally. Recent advances in immunotherapy have introduced promising treatments targeting T cell functionality. Central to the efficacy of these therapies is the role of T cells, which are often rendered dysfunctional due to continuous antigenic stimulation in the tumor microenvironment-a condition referred to as T cell exhaustion.

Cadmium biphasically impacts the adaptive immune system via regulating mitochondrial activation of hematopoietic stem cells in mice.

Cadmium (Cd) is a highly toxic metal in human body, and therefore understanding the immunotoxicity of Cd is significant for public health. The aim of this study was to investigate the role of hematopoietic stem cells (HSC) in regulating the immunotoxicity of Cd. After exposure to 10 ppm Cd via drinking water for up to 9 months, C57BL/6 mice had a suppressed adaptive immune system at day 135 but had an enhanced adaptive immune system at day 270 during Cd exposure.

Super Tough Multifunctional MXene/PAA-CS Double Network Hydrogels with High Mechanical Sensing Properties and Excellent EMI Shielding Performance.

Hydrogels present significant potential in flexible materials designed for electromagnetic interference (EMI) shielding, attributed to their soft, stretchable mechanical properties and water-rich porous structures. Unfortunately, EMI shielding hydrogels commonly suffer from low mechanical properties, deficient fracture energy, and low strength, which limit the serviceability of these materials in complex mechanical environments. In this study, the double network strategy is successfully utilized along with the Hofmeister effect to create MXene/PAA (polyacrylic acid)-CS (chitosan) hydrogels and further strengthen and toughen the gel with (NH)SO solution.

Chronic sleep deprivation disturbs energy balance modulated by suprachiasmatic nucleus efferents in mice.

Background: Epidemiologic researches show that short sleep duration may affect feeding behaviors resulting in higher energy intake and increased risk of obesity, but the further mechanisms that can interpret the causality remain unclear. The circadian rhythm is fine-tuned by the suprachiasmatic nucleus (SCN) as the master clock, which is essential for driving rhythms in food intake and energy metabolism through neuronal projections to the arcuate nucleus (ARC) and paraventricular nucleus (PVN).

Results: We showed that chronic SD-induced aberrant expressions of AgRP/NPY and POMC attributed to compromised JAK/STAT3 signals and reduced energy expenditure in the mice, which can be rescued with AAV-genetic overexpression of BMAL1 into SCN.

Arousal-promoting effect of the parabrachial nucleus and the underlying mechanisms: Recent advances.

The parabrachial nucleus (PBN) is responsible for integrating both internal and external sensory information and controlling/regulating a wide range of physiological processes, such as feeding, thermogenesis, nociceptive and pruritic sensations, and respiration. Recently, the PBN has been found to be involved in mediating wakefulness maintenance, sleep-wake transition, exogenous neuromodulation of awakening, and arousal-promoting process triggered by drastic changes in the internal environments, such as hypercapnia, hypoxia, and hypertension. Multiple neural pathways and subpopulations of neurons are responsible for arousal-promoting effects of the PBN.

A HPLC-assisted mathematical prediction method of ternary solvent systems to develop an intelligent online selection system for countercurrent chromatography solvent system.

Countercurrent chromatography (CCC) is an efficient technique for purifying bioactive natural compounds, but selecting the solvent system can be a time-consuming and crucial process for successful separation.

Synergistic Co-Cu Dual-Atom Nanozyme with Promoted Catalase-like Activity for Parkinson's Disease Treatment.

Neurodegenerative diseases like Parkinson's disease (PD) are intimately associated with oxidative stress due to the excessive highly reactive oxygen species (ROS), leading to the damage of dopaminergic neurons. Herein, we develop a Co-Cu dual-atom nanozyme (CoCu-DAzyme) by uniformly anchoring Co and Cu active sites onto an AlO(OH) substrate that exhibits remarkable catalase-like catalytic activity, far exceeding that of the Co or Cu single-atom counterparts. The following density functional theory calculations reveal that the Co sites efficiently enable HO adsorption, while Cu sites promote charge transfer, synergistically promoting the catalytic decomposition of HO into HO and O.
