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 to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il vector » el vector (Expand search), del vector (Expand search), _ vector (Expand search)

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

• Removing quotes may allow a broader search: (( decrease to decrease lesions decrease ) OR ( decrease _ decrease il vector ))~.
