Research Abstract |
Pluripotent stem cell (iPS/ES cells) showed resistance to CMV. We established iPS cells from human fibroblast using Yamanka factors. iPS showed remarkable resistance to CMV infection. This is the compatible with previous report (Plos one: 10.1371/journal.pone.0017492). We tried to investigate the new factor for this inhibitory phenomenon.The new factor has not been found yet. Instead, we tried to find known receptor (CD29) distribution for CMV in brain. Endothelial cells, pericytes, meninges, choloid plexus and NSPC all express higher level of CD29 than other area of the brain. Co-expression of higher level of CD29 expressing cells and MCMV infected cells were highly correlated. In the brain. We concluded that cytomegalovirus infection primarily initiates infection from high-level CD29 expressing cells in acute infection phase.
