Recombinant adeno-associated virus (rAAV) vectors are great tools for gene transfer due to their ability to mediate long-term gene expression. rAAVs have been used successfully as gene transfer vehicles in multiple animal models of CNS disorders, and several clinical trials are currently underway. rAAV vectors have been used at various stages of development with no apparent toxicity. There are multiple ways of delivering AAV vectors to the mouse CNS, depending on the stage of development. In neonates, intravascular injections into the facial vein are often used. In adults, direct injections into target regions of the brain are achieved with great spatiotemporal control through stereotaxic surgeries. Recently, discoveries of new AAV vectors with the ability to cross the blood brain barrier have made it possible to target the adult CNS by intravascular injections.

Solid-state nanopore is a promising single molecular detection technique, but is largely limited by relatively low resolution to small-size targets and laborious design of signaling probes. Here we establish a universal, CRISPR/Cas-Assisted Nanopore Operational Nexus (CANON), which can accurately transduce different targeting sources/species into different DNA structural probes via a "Signal-ON" mode. Target recognition activates the cleavage activity of a Cas12a/crRNA system and then completely digest the blocker of an initiator.

Contributions to skin sphingolipid abundance are not well characterized, thus the main method of modulating skin lipid levels is the topical application of creams rich with sphingolipids at the skin surface. Evidence that diet and gut microbiome function can alter skin biology proposes an intriguing potential for the modulation of skin lipid homeostasis through gut microbial metabolism, but potential mechanisms of action are not well understood.

Our recent study revealed the presence of mucosal-associated invariant T (MAIT) cells in the meninges, where they express antioxidant molecules to maintain meningeal barrier integrity. Accumulation of misfolded tau proteins are a hallmark of neurodegenerative diseases.

Conjugation, the major driver of the spread of antimicrobial resistance genes, relies on a conjugation pilus for DNA transfer. Conjugative pili, such as the F-pilus, are dynamic tubular structures, composed of a polymerized pilin, that mediate the initial donor-recipient interactions, a process known as mating pair formation (MPF). IncH are low-copy-number plasmids, traditionally considered broad host range, which are found in bacteria infecting both humans and animals.

Agrobacterium-mediated gene transformation method is a vital molecular biology technique employed to develop transgenic plants. Plants are genetically engineered to develop disease-free varieties, knock out unsettling traits for crop improvement, or incorporate an antigenic protein to make the plant a green factory for edible vaccines. The method's robustness was validated through successful transformations, demonstrating its effectiveness as a standard approach for researchers working in plant biotechnology.
