I actually did take a look again through my catalog, back to 12/19, looking for posts that might fit your description, but was unable to find anything that looked likely. Maybe running a search regarding chaga mushrooms and immunology might turn him up.

Regarding the immunological question, I am a bit baffled, as I don't see your statement as a question. Also, do you mean mannose instead of marmose? Interestingly when I sought more information on marmose, I found there was a new species of marmoset discovered in the Amazon, so that was neat.
