Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease total » decreased total (Expand search), increase total (Expand search), decrease fetal (Expand search)
total decrease » quotas decrease (Expand search), to decrease (Expand search), not decrease (Expand search)
decrease treg » decrease the (Expand search), decrease their (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs decrease (Expand search)
decrease t » decrease at (Expand search), decrease _ (Expand search), decrease β (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease treg decrease lesions decrease ) OR ( decrease total decrease t patterns ))~.
