Our time-lapse analyses of infected cells indicate that virus infection may positively activate Rab6-dependent transport to the cell surface, with the number and length of Rab6 positive tubules leaving the Golgi/TGN being greatly enhanced, and long tubules frequently observed to leave the Golgi/TGN area, delivering a large amount of membrane to the cell surface. The gene discussed is RAB6A; the disease is viral infectious disease.
