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)
decreases immune » decreases in (Expand search), decreases lung (Expand search), decreases mmp (Expand search)
skins decreases » skins decrease (Expand search), seeds decreases (Expand search), walking decreases (Expand search)
decrease skins » decrease in (Expand search), increase skin (Expand search), decrease owing (Expand search)
immune objects » immune effects (Expand search), image objects (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 lesions decrease AND decrease ) OR ( decrease skins decreases immune objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease AND decrease ) OR ( decrease skins decreases immune objects ))*.
