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 ipla2 » increased ipla2 (Expand search), decrease il (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
ipla2 based » lipl32 based (Expand search), play based (Expand search), plan based (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 AND decrease lesions decrease ) OR ( decrease _ decrease ipla2 based ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease lesions decrease ) OR ( decrease _ decrease ipla2 based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease lesions decrease ) OR ( decrease _ decrease ipla2 based ))*.
