Summary: Photodynamic therapy (PDT) is a novel therapy that uses specific wavelengths of light to activate photosensitizers and treat tumors. 5-aminolevulinic acid (5-ALA) is a commonly used photosensitizer, but its permeability and targeting are limited. Researchers have developed various 5-ALA nano-delivery systems and achieved good efficacy in tumor treatment.

Summary: Malignant glioma, especially in recurrent situations, has a poor prognosis. Interstitial photodynamic therapy (iPDT) using 5-aminolevulinic acid-induced protoporphyrin IX as a cytotoxic photosensitizer shows promising results in treating recurrent malignant gliomas. Heterogeneous treatment response was observed without significant association with patient characteristics, treatment-related factors, or molecular markers. Further prospective evaluation is needed to identify mechanisms and prognostic factors of favorable treatment response.

Summary: A liposomal nanomedicine with iron ion regulation property has been developed to enhance the photodynamic therapy of 5-ALA. By co-encapsulating 5-ALA and DFO into membrane fusion liposomes, the drug delivery efficiency to tumor cells was improved, leading to the accumulation of photosensitive substances and aggravated DNA damage through iron ion inhibition.

Summary: Photodynamic therapy with 5-aminolevulinic acid hydrochloride is an established method for treating actinic keratosis (AK). Occlusion during ALA incubation can improve the clinical outcome of PDT for AK on hands and arms. Two PD P 506 A-PDT sessions 1-2 weeks apart are an efficacious treatment for AK on hands and arms.

Summary: The study demonstrated that PDT using 5-aminolevulinic acid as a photosensitizer had significant inhibitory activity against C. albicans biofilms. It induced cell apoptosis, cytoplasm degradation, nuclear condensation, and mitochondrial swelling, and reduced mRNA expressions of specific genes. This suggests that ALA-PDT may serve as a potential antifungal strategy for eliminating C. albicans biofilms.

Summary: The study reviewed and analyzed the effectiveness of 5-ALA PDT in vitro experiments for different cancer cell types, finding that the sensitivity to 5-ALA PDT varies across cancer classifications, with stomach cancer showing significantly higher sensitivity compared to other cancers. The analysis suggests the need for a standardized in vitro experimental protocol for 5-ALA PDT in future research.

Summary: Obesity and related metabolic disorders like type 2 diabetes are becoming increasingly prevalent worldwide, prompting the exploration of strategies to combat these conditions by activating brown adipose tissue and converting white adipose tissue to beige fat to increase energy expenditure. Recent advancements in utilizing thermogenic adipocytes through genetic, pharmacological, and cell-based approaches for the treatment of obesity and metabolic disorders in mice and humans are promising for therapeutic potential.

Summary: The prevalence and healthcare burden of obesity and its related metabolic disorders such as type 2 diabetes (T2D) are increasing rapidly. Mitochondria and endoplasmic reticulum (ER) play important roles in insulin resistance and T2D, and their dysfunction may contribute to the progression of these diseases. In this study, the authors found that the formation of mitochondria-associated ER membranes (MAMs) is increased during the differentiation of preadipocytes, and disruption of MAMs impairs cell differentiation and insulin signaling. Additionally, knocking down the protein GRP75, which is involved in MAMs formation, also impairs thermogenesis and glucose utilization in brown adipocytes. These findings suggest that MAMs formation is essential for the proper functioning of adipocytes and insulin signaling, and may be a potential target for therapeutic interventions.

Summary: In this study, patient-derived iPSCs were used to model neurons and investigate the pathogenic mechanism of neurological disorders in MERRF syndrome. The results showed that MERRF neural cells harboring the m.8344A > G mutation exhibited impaired mitochondrial bioenergetic function, elevated ROS levels and imbalanced expression of antioxidant enzymes. Electrophysiological recordings also revealed impairment of neuronal activities in neurons with a high level of the m.8344A > G mutation.

Summary: Mitocytosis is a migrasome-mediated mitochondrial quality-control process that helps maintain mitochondrial quality in migrating cells. The process involves positioning damaged mitochondria at the cell periphery, which avoids binding to inward motor proteins. Enhanced mitocytosis protects cells from mitochondrial stressor-induced loss of mitochondrial membrane potential and mitochondrial respiration, while blocking mitocytosis causes loss of these functions under normal conditions. Physiologically, mitocytosis is required for maintaining mitochondrial membrane potential and viability in neutrophils in vivo.
