Published: September 2011

Neutralizing antibodies (NAb) to an adeno-associated virus (AAV) vector due to previous natural infection with wild-type AAV can significantly limit gene transfer. NAb titers to AAV serotype 2 (AAV2) and AAV8 in human subjects (0 to 18 years) were studied. NAb prevalence is moderate at birth, decreases markedly from 7 to 11 months, and then progressively increases through childhood and adolescence.

Gene therapy with Adeno-Associated Virus (AAV) vectors requires knowledge of their tropism within the body. Here we analyze the tropism of ten naturally occurring AAV serotypes (AAV3B, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAVrh8, AAVrh10 and AAVrh74) following systemic delivery into male and female mice. A transgene expressing ZsGreen and Cre recombinase was used to identify transduction in a cell-dependent manner based on fluorescence.

Atherosclerosis and aortic aneurysms are prevalent cardiovascular diseases in the elderly, characterized by chronic inflammation and oxidative stress. This study explores the role of CircXYLT1 in regulating oxidative stress and vascular remodeling in age-related vascular diseases. RNA sequencing revealed a significant upregulation of CircXYLT1 in the vascular tissues of aged mice, highlighting its potential role in age-related vascular diseases.

Background: Rheumatic heart disease (RHD), which is caused mainly by Group A Streptococcus, leads to fibrotic damage to heart valves. Recently, endothelial‒mesenchymal transition (EndMT), in which activin plays an important role, has been shown to be an important factor in RHD valvular injury. However, the mechanism of activin activity and EndMT in RHD valvular injury is not clear.

Semaphorin 3A (Sema3A) is an axon guidance molecule, which is also abundant in the adult central nervous system (CNS), particularly in perineuronal nets (PNNs). PNNs are extracellular matrix structures that restrict plasticity. The cellular sources of Sema3A in PNNs are unknown.

Adeno-associated viruses (AAVs) are non-pathogenic, replication-deficient viruses that have gained widespread attention for their application as gene therapy vectors. While these vectors offer high transduction efficiency and long-term gene expression, the host immune response poses a significant challenge to their clinical success. This review focuses on the obstacles to evaluating the humoral response to AAVs.
