Does conjugated linoleic acid reduce Crohn's symptoms?

Conjugated linoleic acid from Wikipedia
"Conjugated linoleic acids (CLA) are a family of at least 28[1] isomers of linoleic acid found mainly in the meat and dairy products derived from cud chewing mammals called ruminants. As the name implies, the double bonds of CLAs are conjugated, with only one single bond between them."

"Conjugatedlinoleicacid modulates immune responses in patients with mild to moderately active Crohn's disease" in Clinical Nutrition (2012)
"Oral CLA administration was well tolerated and suppressed the ability of peripheral blood T cells to produce pro-inflammatory cytokines, decreased disease activity and increased the quality of life of patients with CD."

"Probiotic Bacteria Produce Conjugated Linoleic Acid Locally in the Gut That Targets Macrophage PPAR γ to Suppress Colitis" in PLoS ONE (2012)
"Probiotic bacteria modulate gut microbial diversity and favor local production of CLA in the colon that targets myeloid cell PPAR γ to suppress colitis."

"Conjugated linoleic acid (CLA) exerts a protective effect on experimental inflammatory bowel disease...."
