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 faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease treg » decrease the (Expand search), decrease their (Expand search)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may decrease (Expand search)
treg based » tree based (Expand search), reg based (Expand search), trees based (Expand search)

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

• Removing quotes may allow a broader search: (( decrease faster decrease lesions decrease ) OR ( decrease any decrease treg based ))~.
