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 that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (Expand search)
decrease treg » decrease the (Expand search), decrease their (Expand search)
treg object » stress object (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease that decrease lesions decrease ) OR ( decrease cell decrease treg object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease that decrease lesions decrease ) OR ( decrease cell decrease treg object ))*.
