Article Synopsis
  • Adolescent substance use is linked to future addiction, highlighting the importance of understanding the brain's mechanisms behind initiation and frequency of use during this developmental stage.
  • A study of 91 adolescents tracked neural connectivity related to cognitive control, revealing that stronger connections between the dorsal anterior cingulate cortex and the dorsolateral prefrontal cortex can delay substance use onset, while weakened connections predict higher usage frequency.
  • The findings suggest that enhancing cognitive control systems in the brain during early adolescence could prevent substance use, and targeted interventions for those with higher usage might be more effective by focusing on improving awareness and self-regulation processes.

In past decades, the positive role of self-control in students' academic success has attracted plenty of scholarly attention. However, fewer studies have examined the link between adolescents' neural development of the inhibitory control system and their academic achievement, especially using a longitudinal approach. Moreover, less is known about the role of parents in this link.

Article Synopsis
  • Recent research indicates that while there's a focus on parent-child neural similarity using fMRI, more studies are needed to explore its impact on children's emotional well-being and the factors that might influence this relationship.
  • In a study involving 32 parent-child pairs watching an emotionally charged film while undergoing fMRI, results showed that greater neural similarity was linked to better emotional outcomes for children, such as reduced negativity and anxiety.
  • The positive effects of parent-child neural similarity on children's emotional adjustment were particularly significant in families with higher levels of cohesion, suggesting that the context of family relationships plays a critical role in these dynamics.

Tripartite motif-containing protein 5α (TRIM5α) is generally known to block the postentry events of HIV-1. Here, we report an uncharacterized role for TRIM5α in the maintenance of viral latency. Knockdown of TRIM5α potentiates the transcription of HIV-1 in multiple latency models, which is reversed by shRNA-resistant TRIM5α.

Mitochondrial antiviral signaling (MAVS) protein is a core signaling adapter in the retinoid acid-inducible gene-I-like receptor (RLR) signaling pathway that recruits downstream signaling factors, ultimately leading to the activation of type Ⅰ interferons. However, the mechanisms that modulate the RLR signaling pathway by manipulating MAVS are not fully understood. Previous studies suggested that tripartite motif 28 (TRIM28) participates in regulating innate immune signaling pathways by inhibiting the expression of immune-related genes at the transcriptional level.

The COVID-19 pandemic has made an unprecedented shift in children's daily lives. Children are increasingly spending time with screens to learn and connect with others. As the online environment rapidly substitutes in-person experience, understanding children's neuropsychological trajectories associated with screen experiences is important.

The newly emerged severe acute respiratory syndrome (SARS) coronavirus-2 (SARS-CoV-2) can result in dysregulated interferon (IFN) responses that contribute to disease severity. The papain-like protease of SARS-CoV-2 (SCoV2-PLpro) has been previously reported to attenuate IFN responses, but the underlying mechanism is not fully understood. In this study, we found that SCoV2-PLpro potently suppressed IFN production and signaling induced by Sendai virus as well as RIG-I-like receptor (RLR) signaling pathway components, including RIG-I, MAVS, TBK1, TRAF3, TRAF6, and IRF3.

Background: Atypical activity in the salience network (SN) and default mode network (DMN) has been previously reported in individuals with autism spectrum disorder (ASD). However, no study to date has investigated the nature and dynamics of the interaction between these two networks in ASD.

Methods: Here, we aimed to characterize the functional connectivity between the SN and the DMN by using resting-state functional magnetic resonance imaging data from the Autism Brain Imaging Data Exchange and comparing individuals with ASD (n = 325) to a typically developing group (n = 356).

Background: Alcohol is known to modulate the immune system. Neuroinflammatory cytokine dysregulation plays an essential role in the pathophysiology of alcohol dependence (AD). Preclinical studies have indicated that alcohol consumption upregulates the pro-inflammatory cytokine CC motif ligand 11 (CCL11, also known as eotaxin-1).

Oridonin, a natural diterpenoid compound extracted from a Chinese herb, has been proved to exert anti-oxidative stress effects in various disease models. The aim of the present study was to investigate the protective effects of oridonin on oxidative stress-induced endothelial injury in ischaemic stroke. We found oridonin repaired blood-brain barrier (BBB) integrity presented with upregulation of tight junction proteins (TJ proteins) expression, inhibited the infiltration of periphery inflammatory cells and neuroinflammation and thereby reduced infarct volume in ischaemic stroke mice.

Acute traumatic event exposure is a direct cause of post-traumatic stress disorder (PTSD). Amygdala is suggested to be associated with the development of PTSD. In our previous findings, different activation patterns of GABAergic neurons and glutamatergic neurons in early or late stages after stress were found.

The efficacy of gold nanoparticle (AuNP)-assisted radiofrequency (RF)-induced hyperthermia employing the Kanzius device remains controversial. Different from the Kanzius device, modulated electro-hyperthermia (mEHT) utilizes the capacitive-impedance coupled 13.56 MHz radiofrequency (RF) current and has been approved for clinical cancer treatment.

Article Synopsis
  • PTSD is an anxiety disorder marked by distressing memories of trauma and heightened arousal, with the amygdala's activity playing a key role in symptoms.
  • In a study using an animal model of PTSD, researchers found that changes in neuronal activation occurred in the amygdala at different time points following stress exposure.
  • Specifically, one day post-stress showed decreased glutamatergic neuron activation and increased GABAergic neuron activation, while 10 days post-stress revealed increased activation of both neuron types, indicating a shift in brain activity related to PTSD development.

  • Researchers found that reactivating nicotine reward memories can trigger cravings and relapse, but using a specific memory interference technique reduced these cravings in rats and smokers.* -
  • The study involved injecting a protein synthesis inhibitor into rats after they experienced nicotine, which prevented them from relapsing or seeking nicotine again after a break.* -
  • The brain region studied, the basolateral amygdala, showed that different groups of neurons were responsible for storing different types of nicotine reward memories, and selectively targeting these neurons reduced cravings and relapse.*

Article Synopsis
  • The study investigates how memories associated with nicotine can lead to relapse in addiction, specifically focusing on the effects of nicotine reward memories being reactivated.
  • It aims to test a method using an unconditioned stimulus (UCS) to weaken nicotine cravings by administering propranolol to participants after reactivating these memories in both rat and human studies.
  • Results showed varying effects on both rat behavior related to nicotine preference and human ratings of craving, suggesting that further exploration is needed to understand the efficacy of this approach.
