This is a rather poorly-written article. Immune cells secrete cytokines as a part of any immunological response, so the article fails to explain exactly what may set H5N1 apart from most pathogens in its stimulation of the immune system. Hyperstimulation of the immune system is one thing, but this piece makes it sound like something that happens with every inflammatory response is out of the ordinary.
I wonder if we'll now see folks make a run on corticosteroids at online "pharmacies."
Probably. All the sauerkraut is gone.
