And I'm not going to go into detail here, but you actually have proteins that are flowing in your blood plasma that are normally in an inactive state, but when the inflammatory response occurs, these proteins, they get essentially activated and sometimes-- and this is all not 100% well understood-- they become activated, they get cleaved up, and then the cleaved-up versions of those proteins are really good at, in a very nonspecific way, helping to kill off at least some of what's getting-- maybe the bacteria in this case.
