Pulmonary arterial hypertension (PAH) is a multi-etiological chronic disease characterized by a progressive elevation in pulmonary resistance and vascular remodeling. Its pathogenesis is complicated. Recently, emerging researches suggest that autophagy, as a self-protection mechanism maintaining the intracellular environment homeostasis in eukaryotes, participate in the occurrence and development of various types of PAH. Autophagy can regulate the survival, apoptosis of pulmonary vascular wall cells and secretion of vasoactive substances and inflammatory cytokines, thus influencing pulmonary vascular homeostasis. Some drugs based on regulating autophagy activity can effectively improve the prognosis of PAH. In this article, the regulatory role of autophagy on the development of pulmonary hypertension is reviewed to provide insight into PAH and its treatment.

Mechanisms of Autophagy in Ineffective Reperfusion After Ischemic Stroke.

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury.

Objective: This study aims to investigate how the E3 ubiquitin ligase LITAF influences mitochondrial autophagy by modulating MCL-1 ubiquitination, and its role in the development of epilepsy.
Methods: Employing single-cell RNA sequencing (scRNA-seq) to analyze brain tissue from epilepsy patients, along with high-throughput transcriptomics, we identified changes in gene expression. This was complemented by in vivo and in vitro experiments, including protein-protein interaction (PPI) network analysis, western blotting, and behavioral assessments in mouse models.
Beta-propeller Protein Associated Neurodegeneration (BPAN) is a devastating neurodevelopmental and neurodegenerative disease linked to variants in . Currently, there is no cure or disease altering treatment for this disease. This is, in part, due to a lack of insight into early phenotypes of BPAN progression and 's role in establishing and maintaining neurological function.

( ) thwarts innate immune defense mechanisms in alveolar macrophages (AMs) during the initial stages of infection and in recruited bone marrow-derived cells during later stages of infection. However, how protective inflammatory responses are achieved during infection and the variation of the response in different macrophage subtypes remain obscure.

Nevertheless, condensates have been shown to interact with lipid membranes in diverse biological processes, such as autophagy and T-cell activation. Since many condensates are known to have a net surface charge density and associated electric potential(s), we hypothesized that they can induce a local membrane potential.
