Still more cathelicidins, this time in the bladder,
http://www.nature.com/nm/journal/v12/n6/full/nm1407.html
but the article suggests to me that cathelicidins could
be tested thru urine testing. The epithelial bacterial
defenses here suggest that if cathelicidins are a factor in
rosacea, they may be present for defense against bacteria.
There are a lot of bacteria in the sinuses so the proximity
is not much of a stretch. I talk more about that in my
"Notes on Rosacea" article, url in my profile.
