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)
dual processing » visual processing (Expand search), neural processing (Expand search), dual process (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)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease treg decrease dual processing ) OR ( decrease NOT decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease treg decrease dual processing ) OR ( decrease not decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease treg decrease dual processing ) OR ( decrease not decrease lesions decrease ))*.
