Perhaps you should try some spelling variations:

decrease decrease » decrease release (Expand search), decreases disease (Expand search), disease decreases (Expand search)
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 can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)

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

• Removing quotes may allow a broader search: (( decrease can decrease decrease processes ) OR ( decrease lesions decrease hiv error ))~.
