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 trees » decrease treg (Expand search), decreases stress (Expand search), decreases areas (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (Expand search)
trees doi » tree doi (Expand search), trees does (Expand search), trees i (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease at decrease lesions decrease ) OR ( decrease on decrease trees doi ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decrease lesions decrease ) OR ( decrease on decrease trees doi ))*.
