We have identified five key trends to watch. 1. Improved capsids. The viral capsid is a critical component of viral-vector gene therapy. It determines which cells are targeted, the efficiency of cell entry, and the probability that the gene therapy is detected and eliminated by the immune system. Capsids are broadly classified according to their structure. The majority of the viruses have capsids with either helical or icosahedral structure. Some viruses, such as bacteriophages, have developed more complicated structures due to constraints of elasticity and electrostatics.
