SEC13 and infection: In this study 37 genes involved in exocytosis and protein export from the endoplasmic reticulum to the Golgi apparatus were found to be differentially expressed during different stages of infection, including SEC1, SEC3, SEC4, SEC13, SEC14, SEC16, SEC23, SEC24, SEC61, some SNARE proteins, and Rab GTPases (Table 4; Additional file 7).
