| Research Abstract |
Virus infections are one of the largest threats of humanity in modern society with scientific and technological advances, of which the H1N1 pandemic in 2009 would be a practical example. We have previously reported that PI3K bound to and activated by Ras plays a crucial role in the regulation of endocytosis by deciphering the signal transduction pathways with the best use of fluorescence bioimaging techniques.
In this study, we found that Ras-PI3K signaling is required for influenza virus infection, and identified intracellular calcium as a key molecule to regulate a series of influenza virus infection processes. It might also be expected to lead to a new concept of antivirus therapeutics through application of these results.
