Lentiviral-Mediated Systemic RNA Interference In Vivo

The shRNA-encoding lentivirus has been widely used for gene manipulation in preclinical studies. It is a powerful tool for gene transfer and shows promise in its ability to efficiently transduce immune cells and hematopoietic stems cells, which are the initial therapeutic target of autoimmune diseases, and considering that gene manipulation of these cells is usually difficult to achieve using other techniques. In previous chapters, we have described how to produce concentrated shRNA-encoding lentiviral particles. Here, systemic in vivo application of lentivirus, including viral quantification prior to injection, intraperitoneal injection, and quantification of integrated provirus, is introduced.
