Apoptosis in infection

Publication date: Available online 4 November 2017Source: Microbes and InfectionAuthor(s): Georg HäckerAbstractApoptosis is one of the principal responses that human cells have at their disposal when faced with changes in their environment. Microbial infection is a massive challenge to a cell, and it is unsurprising that the apoptosis apparatus has been implicated in numerous infections. However, looking at the available data, the impression is one of bewildering complexity. Microbial proteins and other molecules that are often poorly understood interact, with uncertain specificity, with host cell components of varying function, triggering signalling pathways that are ambiguously linked to the apoptotic machinery. Accordingly, many pathogens have been found in different studies both to induce and to inhibit apoptosis. I will here try to present some of the principles of apoptosis and of infection, and to provide a viewpoint on the question how the two are linked. I will further give the reasons for my personal opinion that apoptosis-induction is in most infections beneficial to the host.
