Talk:T helper 17 cell
From Wikipedia, the free encyclopedia
[edit] Existence of Th17 cells in humans
I removed the following from the article due the lack of sources;
"It must be noted that there is no direct evidence for the existence of this cell type in humans, although it seems that IL-17 can be produced by some T helper cells. It is also important to note that a major proportion of IL-17 found in humans is produced from an unknown source, macrophages/monocytes, neutrophils and other immune cells produce this proinflammatory cytokine as well."
Given that the first part of the statement calls into question the very existence of the article subject, a reference to the opinion of a noted academic is the minimum that should be provided here. I'm not sure what to make of the second part but it should be referenced and preferably be written so as to make it's relevence clear. DoktorDec (talk) 01:20, 16 December 2007 (UTC)
