Other examples of overzealous immune responses in disease include hypersensitivities, such as allergies and asthma. Most multicellular organisms possess an "innate immune", generally comprising a set of genetically-encoded responses to pathogens, that does not change during the lifetime of the organism. http://en.wikipedia.org/wiki/Immune_system   (2074 words)      Immune System Preliminary observations on the effects of the Chinese medicinal herbs Astragalus membranaceous and Ligustrum lucidum on lymphocyte blastogenic responses.
