It clarifies the influence mechanism of controlling shareholders' equity pledges, margin trading and securities lending, and stock price crash risk from the perspective of corporate governance, etc. This paper establishes a main and interaction effect regression model to empirically test the impact mechanism of controlling shareholders' equity pledge on stock price crash risk and the moderating effect of margin trading and securities lending in the process of this impact based on the measures of stock price crash risk, controlling shareholders' equity pledge level, as well as margin trading and securities lending transaction size, using China's A-share listed companies from 2010 to 2020 as the sample. It finds that: (i) The higher the controlling shareholder's equity pledge ratio of listed companies, the lower the stock price crash risk.

Inhibition of mitophagy via the EIF2S1-ATF4-PRKN pathway contributes to viral encephalitis.

Introduction: Mitophagy, a selective form of autophagy responsible for maintaining mitochondrial homeostasis, regulates the antiviral immune response and acts as viral replication platforms to facilitate infection with various viruses. However, its precise role in herpes simplex virus 1 (HSV-1) infection and herpes simplex encephalitis (HSE) remains largely unknown.

Objectives: We aimed to investigate the regulation of mitophagy by HSV-1 neurotropic infection and its role in viral encephalitis, and to identify small compounds that regulate mitophagy to affect HSV-1 infection.

Nicotinamide n-Oxide Attenuates HSV-1-Induced Microglial Inflammation through Sirtuin-1/NF-κB Signaling.

HSV-1 is a typical neurotropic virus that infects the brain and causes keratitis, cold sores, and occasionally, acute herpes simplex encephalitis (HSE). The large amount of proinflammatory cytokines induced by HSV-1 infection is an important cause of neurotoxicity in the central nervous system (CNS). Microglia, as resident macrophages in CNS, are the first line of defense against neurotropic virus infection.

The Role of REC8 in the Innate Immune Response to Viral Infection.

REC8 meiotic recombination protein (REC8) is a member of structural maintenance of chromosome (SMC) protein partners, which play an important role in meiosis, antitumor activity, and sperm formation. As the adaptor proteins of RIG-I-like receptor (RLR) signaling and cyclic GMP-AMP synthase (cGAS)-DNA signaling, the activity and stability of MAVS (mitochondrial antiviral signaling protein; also known as VISA, Cardif, and IPS-1) and STING (stimulator of interferon genes; also known as MITA) are critical for innate immunity. Here, we report that REC8 interacts with MAVS and STING and inhibits their ubiquitination and subsequent degradation, thereby promoting innate antiviral signaling.

Proteomic analysis revealed the roles of YRR1 deletion in enhancing the vanillin resistance of Saccharomyces cerevisiae.

Background: Vanillin is one of the important phenolic inhibitors in Saccharomyces cerevisiae for bioconversion of lignocellulosic materials and has been reported to inhibit the translation process in cells. In our previous studies, it was confirmed that the deletion of the transcription factor gene YRR1 enhanced vanillin resistance by promoting some translation-related processes at the transcription level. In this work, we investigated the effects of proteomic changes upon induction of vanillin stress and deletion of YRR1 to provide unique perspectives from a transcriptome analysis for comprehending the mechanisms of YRR1 deletion in the protective response of yeast to vanillin.

CD19CD24CD38 Regulatory B cells Involved in Hepatic Alveolar Hydatid Infection in Humans.

In infections causing alveolar echinococcosis (AE) in humans, immune tolerance and/or down-regulation of protective immunity is a marked characteristic of this chronic disease.
