So you want to be an intelligence analyst. Students occasionally write to me and ask for advice on getting a job in the Intelligence Community. (I became an intelligence analyst at DIA after undergrad. I was there for about three years, and after that, I did a few years of consulting for various intel agencies.) The below is a gist of that advice. It is heavily biased by my own experience, and none of the below is meant to be universal.
Apoptosis, or programmed cell death, is a naturally occurring process in the body. It involves a controlled sequence of steps in which cells signal self termination. Apoptosis works to keep the body's natural cell division process of mitosis in check.
Cell lysis. Cell lysis is a common outcome of viral infection. It consists of a disruption of cellular membranes, leading to cell death and the release of cytoplasmic compounds in the extracellular space.Lysis is actively induced by many viruses, because cells seldom trigger lysis on their own. Indeed eukaryotic cells rather tend to trigger apoptosis when attacked by viruses.Lytic replication: Most non-enveloped virus, and few enveloped viruses require cell lysis in order to release new virions from the infected cell.t consists of a disruption of cellular membranes, leading to cell death and the release of cytoplasmic compounds in the extracellular space. Lysis is actively induced by many viruses, because cells seldom trigger lysis on their own. Indeed eukaryotic cells rather tend to trigger apoptosis when attacked by viruses.
