Extensive length and homology dependent chimerism in pool-packaged AAV libraries.

Adeno-associated viruses (AAVs) have emerged as the foremost gene therapy delivery vehicles due to their versatility, durability, and safety profile. Here we demonstrate extensive chimerism, manifesting as pervasive barcode swapping, among complex AAV libraries that are packaged as a pool. The observed chimerism is length- and homology-dependent but capsid-independent, in some cases affecting the majority of packaged AAV genomes.

Technical and biological sources of noise confound multiplexed enhancer AAV screening.

-acting regulatory enhancer elements are valuable tools for gaining cell type-specific genetic access. Leveraging large chromatin accessibility atlases, putative enhancer sequences can be identified and deployed in adeno-associated virus (AAV) delivery platforms. However, a significant bottleneck in enhancer AAV discovery is charting their detailed expression patterns , a process that currently requires gold-standard one-by-one testing.

Mitochondria and NLRP3: To die or inflame.

Mitochondria play critical roles in intrinsic apoptosis and NLRP3 inflammasome activation, but how these processes are interconnected remains unclear. In this issue of Immunity, Saller et al. unveiled the complexity of NLRP3 activators, highlighting mitochondria's roles in switching apoptosis to NLRP3 inflammasome activation.

Predictors of dilation difficulty in gender-affirming vaginoplasty.

A necessary component of postoperative care in gender-affirming vaginoplasty is the dilation of the neovaginal canal. Difficulty with dilation can cause patient pain and distress, often decreasing compliance and leading to partial or complete closure of the neovaginal canal. This study sought to evaluate the sociodemographic, operative, and comorbid characteristics that contribute to patient difficulty with neovaginal dilation.

The Impact of Administrative Districts and Urban Landscape on the Dispersal of Aedes aegypti via Genetic Differentiation.

Mosquito-borne diseases affect millions and cause numerous deaths annually. Effective vector control, which hinges on understanding their dispersal, is vital for reducing infection rates. Given the variability in study results, likely due to environmental and human factors, gathering local dispersal data is critical for targeted disease control.
