Summary: This study developed a mouse model with depolymerized orthogonal arrays of particles (OAPs) to investigate the importance of OAP formation in Aquaporin-4 (AQP4). The results showed that the OAP structure of AQP4 plays a key role in its polarized expression in astrocytic endfeet processes at the blood-brain barrier. Manipulating the OAP formation of AQP4 may provide a new intervention strategy for cerebral cellular edema caused by stroke and traumatic brain injury.

Summary: A human IgG monoclonal antibody called L13 showed potential as a therapeutic approach for both ischemic and hemorrhagic stroke by selectively inhibiting MMP-9 activity and reducing brain tissue injury. Treatment with L13 improved neurological outcomes and attenuated BBB breakdown in mouse stroke models. The antibody also neutralized MMP-9 activity in stroke patients' sera and brain tissues, suggesting its clinical application.

Summary: The blood-brain barrier is important for limiting drug delivery to the brain, but it also plays a crucial role in nutrient entrance. Peptide shuttles offer a promising strategy for increasing drug transport across the blood-brain barrier by utilizing its natural transport mechanisms. In recent years, the field of peptide shuttles has significantly evolved, with various classifications and sources being explored.

Summary: A study explored the use of beard nanoscale particles (BNPs) derived from young Asian males to load antidepressants and demonstrated therapeutic effects on depression. BNPs showed favorable photothermal conversion capability, prominent BBB permeability under near-infrared irradiation, reliable biocompatibility, and a pivotal role in redox equilibrium for scavenging ROS induced by depression. Additionally, behavioral and biochemical experiments confirmed significant depression-ameliorating effects in vivo.

Summary: The study investigated the association between MMP-9 levels and phenotypes of moyamoya disease (MMD). Higher MMP-9 expression was found in adult MMD patients, especially in hemorrhagic-onset cases. Elevated serum MMP-9 level (>1,011 ng/ml) may serve as an independent risk predictor for hemorrhagic strokes in adult MMD patients.

Summary: This article discusses the relationship between the functional single nucleotide polymorphism (SNP) at position -1562C/T within the MMP-9 gene and the development of nervous system diseases. The functional polymorphism affects the activity of the MMP-9 gene promoter and thereby alters the expression of MMP-9. This can change the likelihood of disease occurrence and modify the course of certain brain diseases.

Summary: Brain tumours have a poor prognosis due to the challenges posed by the blood-brain barrier (BBB) in drug delivery. The heterogeneity of the blood-brain tumour barrier (BBTB) limits the success of relying on its disruption for effective drug concentrations in tumours. Therefore, designing drugs and delivery strategies to overcome the 'normal' BBB is crucial for treating brain tumours effectively.

Summary: The research revealed that neuronal uptake of L-lactate leads to intracellular acidification, triggering H+ extrusion to activate ASIC1a channels, propagating Ca2+ signals to mitochondria to enhance respiration. L-isomer of lactate has a greater impact on ASIC1a compared to D-isomer, due to the preference of lactate transporters for L-lactate.

Summary: Mitochondrial dysfunction is a major cause of neuronal death after stroke, and intercellular mitochondrial transfer shows promise as a potential therapeutic approach. Neurons release more mitochondria when exposed to challenges like acidosis, hydrogen peroxide, NMDA, or glutamate, which are then engulfed by adjacent astrocytes. This transfer may serve as a signaling mechanism to mediate the interaction between neurons and astrocytes.

Summary: Sphingosine-1-phosphate (S1P) plays a role in the pathophysiology of neurological injury after aneurysmal subarachnoid haemorrhage (aSAH). The literature agrees that S1P increases in cerebrospinal fluid following aSAH and contributes to cerebral artery vasospasm. However, the role of S1P in the parenchyma is less clear, with conflicting studies suggesting both beneficial and harmful effects. This review provides a concise interpretation of the conflicting data and discusses the potential repurposing of S1P receptor modulators for aSAH.

Summary: Depression has a higher incidence in women compared to men, and this study investigated the impact of sex on depressive behaviors and underlying mechanisms using a corticosterone-induced depression model in mice. The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
