Southeast Regional Office, Atlanta, GA Since an estimated 1031 virus-like particles exist on the Earth and they are present in the blood, nose, mouth, lung, vagina, gastrointestinal tract, conjunctiva, skin, and the mammalian genome, viruses appear to play a major role in human life (242, 243). Other current clinical trials include a phase II trial using a retroviral vector to transfer ADA into hematopoietic stem cells to treat ADA-SCID (NCT00598481). Although AAV offers the expression of a therapeutic gene for nearly 1 year without integrating into the host's chromosomes, applying CRISPR/Cas9 technology would resolve long-term expression and mutagenesis issues.

Adding empty vectors of AAV to the final vector preparations to serve as a decoy and developing new vectors with high transduction and gene expression potential as well as better understanding of T-cell response to all AAV serotypes in clinical settings would reduce inflammation, immune response, and other viral particle-associated side effects because capsid is the primary interface with the target cell that defines pharmacological, immunological, and molecular properties (150, 207, 212, 213). This drug is specifically designed to treat diffuse large B-cell lymphoma (DLBCL), a common aggressive NHL that accounts for three out of every five cases. In the treatment of X-linked SCID, CD34+ hematopoietic stem cells were transduced with murine gammaretroviral vector, which led to an increase in immune function, but 5 patients developed T cell leukemia because of insertional mutagenesis into oncogenes (185).

AAV vectors are commonly delivered to patients by systemic, intramural, central nervous system, cardiac, and pulmonary delivery but certain sites of the human body elicit no immune response to injection of antigens or viral particles because the BBB prevents the entry of antibodies or resting lymphocytes and the absence of traditional antigen-presenting cells. Kuo CY, Kohn DB. (2012) 86:1623–37. Since viral infection depends on the expression of target cell surface receptors and viral envelope protein, designing and constructing to produce efficient and cell-, tissue- and disease-specific recombinant RV vectors are necessary to obtain the expected clinical outcome. Germline editing dominates DNA summit. Location: Cohen IG, Adashi EY. Herpes simplex virus vector-mediated gene delivery of poreless TRPV1 channels reduces bladder overactivity and nociception in rats. This creates broad tissue tropism and a nodal for AV transduction efficiency, giving an opportunity to manipulate binding sites for CAR and other ligands to de-target AV infection, an essential feature of popular viral vectors used in gene therapy. Lentivirus has been used to treat X-SCID, cancers and monogenic diseases. Trends Microbiol.
