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)
immune objects » immune effects (Expand search), image objects (Expand search)
in decreases » in decreased (Expand search), and decreases (Expand search), ivm decreases (Expand search)

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

• Removing quotes may allow a broader search: (( decrease lesions decrease AND decrease ) OR ( decrease in decreases immune objects ))~.
