EM analysis of cells depleted of PI(4,5)P 2 . HeLa (B) cells depleted of PI(4,5)P2 by transient expression of 5ptaseIV were infected with BTV-1 and analysed for virus particle production. Controls (A) consist of HeLa cells that have not been depleted of PI(4,5)P2 but infected with BTV-1. The presence of virus particles in cell section (upper panel) is indicated by arrows. Lower panels are magnified section. The bars represent magnification of 500 nm.
