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 treg » decrease the (Expand search), decrease their (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs decrease (Expand search)
decrease age » decrease the (Expand search), decrease and (Expand search), decrease akt (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)
age basic » are basic (Expand search), care basic (Expand search), late basic (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 treg decrease ) OR ( decrease lesions decrease age basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decrease treg decrease ) OR ( decrease lesions decrease age basic ))*.
