Summary: Cell death is a normal and essential component of development and homeostasis, but dysregulation of this process underlies most human diseases. Autophagy is a process mediated by the formation of double membrane vesicles, which allows cells to survive stresses and may also mediate cell death during development and pathogenesis.

Summary: Stem cell therapies show promising effects in restoring damaged tissue, but multiple types of programmed cell death post-transplantation can compromise their efficiency. Understanding and targeting cell death signaling pathways are crucial for successful stem cell therapies in treating diabetes and related diseases.

Summary: This study reveals the important role of dysfunctional autophagy in the pathogenesis of major depressive disorder (MDD). The expression of NRBF2 is attenuated in the dentate gyrus (DG) under chronic stress and its deficiency impairs autophagic flux in adult neural stem cells (aNSCs). Loss of NRBF2 disrupts the neurogenesis-related protein network and leads to the depression-like phenotype, while overexpressing NRBF2 rescues impaired adult hippocampal neurogenesis (AHN) and depression-like phenotype in mice.

Summary: Cystinosis is a lethal genetic disease with specific treatments. The cellular mechanisms are still unknown, but programmed cell death and apoptosis may be involved. Studies have shown that apoptosis rate is increased in cystinosis, but can be partially reversed with cysteamine.

Summary: Mesenchymal stem cells (MSCs) have been extensively studied for their immunomodulatory properties in inflammatory diseases. Recently, MSC-derived extracellular vesicles (MSC-EVs) have gained attention as a major pathway for intercellular communication. This review summarizes the potential influences of MSC-EVs on different types of programmed cell death and diseases, and discusses the therapeutic effects, current research progress, and challenges of clinical applications of MSC-EVs. Understanding the regulation of inflammation-associated programmed cell death by MSC-EVs is important for identifying molecular mechanisms and modulatory targets.

Summary: In this paper, we reviewed the role of calpain in various programmed cell death processes, such as apoptosis, mitochondrial-mediated necrosis, autophagy-dependent cell death, and parthanatos, at neutral pH. Moreover, we discussed the abnormal activation of calpain during myocardial ischemia-reperfusion, the effect of calpain on myocardial repair, and the potential future research directions of calpain.

Summary: This review article addresses the enigmatic role of the p53 transcription factor and tumor suppressor in programmed cell death during embryonic development. Contradictory results regarding the dependence of pluripotent embryonic stem cells on p53 for cell death are reconciled based on experimental conditions. The review concludes that p53 is not required for mouse embryonic development, but can accelerate programmed cell death in certain conditions. Additionally, DNA damage in differentiated cells induces p53-dependent cell cycle arrest and senescence.

Summary: SIRT1 plays a significant role in cancer regulation by regulating cellular localization and deacetylation activity. Its multifactorial role in autophagy regulates cancer-associated cellular phenotypes, aiding cellular survival and cell death. SIRT1-mediated deacetylation of autophagy-related genes and associated signaling mediators controls carcinogenesis.

Summary: Stem cell-based therapy offers hope for tissue repair and functional recovery, but challenges arise from the high death percentage of transplanted stem cells. Investigating the mechanisms of stem cell death and targeting molecular pathways could enhance stem cell viability and transplantation success, though the complexity of cell death networks presents challenges in exploring mechanisms and therapeutic targets.

Summary: Programmed cell death (PCD) is a universal process that regulates cellular homeostasis and plays a crucial role in disease conditions, including cancer. Apoptosis is a major PCD, but cancer cells develop resistance to it, necessitating the search for alternative forms of programmed cell death such as paraptosis. Paraptosis is characterized by vacuolation and damage to cellular structures and has potential therapeutic implications in cancer treatment.

Summary: Neuronal loss is a vital feature of temporal lobe epilepsy, and the exact mechanism is not fully understood. This study investigated the involvement of gasdermin D (GSDMD)-mediated pyroptosis and the crosstalk among pyroptosis, apoptosis, and necroptosis in the pathogenesis of TLE. The results suggest that GSDMD-mediated pyroptosis contributes to TLE, but inhibition of GSDMD triggers crosstalk between pyroptosis and apoptosis, exacerbating neuronal loss and seizure susceptibility.

Summary: YAP plays a critical role in regulating tumor progression and is closely related to programmed cell death (PCD). YAP activity can be regulated by kinase cascade pathways and other proteins. It has been found that YAP can affect multiple forms of PCD and act as a bridge between different forms of PCD in tumor development.

Summary: This study successfully established a rat model based on the genetic-environmental interaction, which exhibited phenotype characteristics similar to human AD in terms of cognitive function, brain microstructure, and immunohistochemistry. The genetic factor (APP mutation) and the environmental factor (acrolein exposure) accounted for 39.74% and 33.3% of the AD-like phenotypes in the model, respectively.

Summary: This study examines the functional connectivity changes in individuals with sudden sensorineural hearing loss (SSNHL) at the integrity, network, and edge levels. The findings reveal reduced intranetwork connectivity strength and increased internetwork connectivity in SSNHL patients. These alterations are associated with the duration of SSNHL and Tinnitus Handicap Inventory scores. The study provides crucial insights into the neural mechanisms of SSNHL and the brain's network-level responses to sensory loss.

Summary: In the early stages of SAD, memory impairment is strongly correlated with cortical levels of soluble amyloid-beta peptide oligomers. A beta disrupts glutamatergic synaptic function and leads to cognitive deficits. This article describes the pathogenic mechanisms underlying cerebral amyloidosis, involving amyloid precursor protein synthesis, A beta residue clearance processes, and the role of specific molecules.

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.

Summary: This study observed changes in brain infarction and blood vessels in rats during neonatal hypoxic ischemic encephalopathy (NHIE) modeling using Transcranial Doppler Ultrasonography (TCD). Longer duration of hypoxia was associated with more severe nerve damage. TCD can dynamically monitor cerebral infarction after NHIE modeling, which may serve as a useful auxiliary method for evaluating animal experimental models.
