WebThe use of a defective or attenuated viral or bacterial vector to deliver vaccines can offer improved immunogenicity as a result of a wide tropism of the vector, including that of antigen-presenting cells, as well as being able to stimulate innate immune responses that, in turn, stimulate adaptive immune responses to the encoded vaccine ... WebAug 4, 2024 · The Nobel committee likened CRISPR-Cas9, a repurposed bacterial anti-viral defense system, to “genetic scissors” capable of rewriting the genetic code of any organism, including humans. Watching the announcement via YouTube on my phone before dawn in my New York apartment, I was almost as stunned as the winners.

WebViral vectors are used to deliver genes to cells. They can either add a gene (knock-in) to study the function of a particular gene or to delete a gene (knock-down) to study the effects of gene deletion or reduction. All work with viral vectors is subject to the NIH Guidelines for Recombinant or Synthetic Nucleic Acids, and as such, all work ...
