The application of infectious clone technology to herpesvirus biology has revolutionized the study of these viruses. Previously the ability to manipulate these large DNA viruses was limited to methods dependent on homologous recombination in mammalian cells. However, the construction of herpesvirus infectious clones using bacterial artificial chromosome vectors has permitted the application of powerful bacterial genetics for the manipulation of these viruses. A method is described for the construction and characterization of a gene inactivation library of Bovine herpesvirus 1 using an infectious clone. The method utilizes transposon-mediated gene inactivation, which permits gene inactivation without any prior knowledge of the viral genomic sequence. Furthermore, as the genetic manipulation is performed in bacteria the inactivation of those viral genes that are essential for viral replication is also possible. The method described here can be readily applied to any herpesvirus clone and provides the tools for precise characterization of all the genes contained within a herpesvirus genome.

Alzheimer's disease (AD) remains a major challenge in developing effective treatments due to its complex pathophysiology, including the accumulation of amyloid-beta plaques and tau tangles. Small interfering RNA (siRNA) technology offers promise for targeted gene silencing, but effective delivery to the central nervous system remains a significant obstacle. Viral vectors have emerged as potent delivery vehicles for transporting siRNA to neural tissues.

Misfolding of the cellular PrP (PrP) protein causes prion disease, leading to neurodegenerative disorders in numerous mammalian species, including goats. A lack of PrP induces complete resistance to prion disease. The aim of this work was to engineer Alpine goats carrying knockout (KO) alleles of PRNP, the PrP-encoding gene, using CRISPR/Cas9-ribonucleoproteins and single-stranded donor oligonucleotides.

Background: HD is a devastating neurodegenerative disorder caused by the expansion of CAG repeats in the HTT. Silencing the expression of mutated proteins is a therapeutic direction to rescue HD patients, and recent advances in gene editing technology such as CRISPR/CasRx have opened up new avenues for therapeutic intervention.
Methods: The CRISPR/CasRx system was employed to target human HTT exon 1, resulting in an efficient knockdown of HTT mRNA.

A spherical nucleic acid (SNA, AuNPs-aptamer) into CRISPR/Cas12a system combined with poly T-template copper nanoparticles as fluorescence reporter was fabricated to establish an amplification-free sensitive method for Staphylococcus aureus (S. aureus) detection. This method, named PTCas12a, utilizes the concept that the bifunction of SNA recognizes the S.
