SOAT1 and infection: In the regulated process of cell apoptosis, porin plays a pivotal role in releasing an apoptogenic factor, namely Cytc. Pathogen infection activates the Janus kinase/signal transducers and activators of transcription (JAK/STAT) to down-regulate porin expression and therefore inhibit cell apoptosis as an aid to pathogen infection, survival, development, and multiplication inside infected cells (Alberdi et al., 2015; de la Fuente et al., 2016).
