Risks for using retroviruses, adenoviruses, and lentiviruses as vectors in gene therapy include all of the following except:
A) the exogenous gene may cause disease if overexpressed or expressed in certain cell types.
B) contaminants may be introduced during vector manufacture.
C) antitumor responses by overexpression of cytokines may occur.
D) there is a potential for recombination of gene therapy vectors with human endogenous sequences.

Question

Quizplus · Accepted Answer

Antitumor responses by overexpression of cytokines are not a risk associated with using viral vectors in gene therapy. Instead, this is a potential therapeutic benefit. The other options are valid risks associated with using viral vectors.
