Summary: Recent research on Adeno-associated viruses (AAVs) using high-resolution native mass spectrometry has revealed that the capsids of different AAV serotypes assemble stochastically, leading to a highly heterogeneous population of capsids with varying compositions. Even the most abundant VP stoichiometry represents only a small percentage of the total AAV population. The systematic scoring of simulations against experimental native MS data offers a sensitive new method to characterize these therapeutically important heterogeneous capsids.

Summary: Adeno-associated viruses (AAV) are widely used for gene therapy, and monoclonal antibodies against various AAV serotypes have been developed. Previous studies suggested that neutralizing antibodies inhibit binding to glycan receptors or interfere with post-entry steps. However, recent research has identified a protein receptor and revealed that antibody interference with protein receptor binding may be the predominant mechanism of neutralization.

Summary: The membrane-associated accessory protein (MAAP) is identified as a novel viral egress factor that promotes the secretion of AAV serotypes. MAAP contains a cationic amphipathic domain critical for AAV secretion. Restoring MAAP expression can rescue the secretion defect in various AAV serotypes with mutated start sites.

Summary: Diabetic retinopathy is a leading cause of blindness associated with excessive angiogenesis. Researchers have developed a novel antiangiogenesis agent by modifying the structure of wondonin marine natural products, resulting in improved bioactivity and selectivity. This compound, 31, shows potential as a lead for developing small-molecule drugs to treat diabetic retinopathy and to uncover new mechanisms of angiogenesis.

Summary: One of the key challenges in gene therapy is to overcome pre-existing and therapy-induced immune responses, as well as to enhance the distribution and activity of AAV in target tissues. Interdisciplinary approaches may help overcome these obstacles and create new opportunities for precision gene therapy.

Summary: Research on adeno-associated virus (AAV) and its recombinant vectors, as well as fluorescence microscopy imaging, is rapidly advancing due to clinical applications and new technologies. These topics intersect as high and super-resolution microscopes enable the study of spatial and temporal aspects of cellular virus biology. Methods for labeling and detecting AAV proteins and DNA have also evolved. This review provides an overview of these interdisciplinary developments and their technological and biological implications.

Summary: New AAV variants with enhanced cellular binding, uptake, and transduction have been evolved through infectious cycling, with one able to recognize sulfated glycosaminoglycans and another switching receptors from AAVR to integrin beta 1. The visualization of the AAVhum.8 capsid revealed a newly acquired integrin recognition motif, providing insights into designing viruses with improved attributes for gene therapy applications.

Summary: In this study, the researchers investigated the role of furin in AAV4 transduction and found that furin plays a regulatory role. Knocking out the furin gene led to increased binding, uptake, and transcript levels of AAV4, but had no effect on postentry steps. The researchers also observed an increase in 2,3-O-linked sialoglycan staining in furin KO cells. These findings suggest that furin may regulate AAV and other viral infections by influencing cellular sialoglycan expression.

Summary: Clinical implementation of inhaled gene therapy using adeno-associated virus (AAV) vector has been challenging due to difficulty in transducing lung airway cells. However, by combining AAV serotype 6 (AAV6) with extracellular vesicles (EVs), researchers have discovered a method that greatly enhances gene expression in respiratory cells, offering a safe and effective treatment strategy.

Summary: Gliomas, the most common intracranial malignancies, often have poor prognosis due to their invasiveness, tendency to relapse, and resistance to traditional treatment methods. Nitric oxide (NO) metabolism plays a crucial role in glioma development and treatment, particularly in its effects on stem cells and immune mechanisms.

Summary: This study identified a considerable amount of TrxR1 protein in GBM tissues, suggested TrxR1 as an attractive drug target, and highlighted AF as a potential off-patent drug candidate in GBM therapy. Treatment with AF decreased viability of GBM cells, increased ROS levels, and its cytotoxic effect was potentiated by treatment with MEN.
