When researchers transferred antibody - rich serum from vaccinated to unvaccinated mice, the unvaccinated animals were also protected from later H5N1 infection, an indication that the protection came from antibodies rather than from other immune system components. (sciencedaily.com)
Looking for immune abnormalities throughout the lifespan of the mice, the group found that most immune system components stayed the same in number, but a type of brain - resident immune cells called microglia that are known first responders to infection begin to divide and change early in the disease.
