Perhaps you should try some spelling variations:
antigen processing » antigen presenting (Expand search), ration processing (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 antigen » release antigen (Expand search), decrease nitrogen (Expand search), decreases mitogen (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (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 lesions decrease antigen processing ) OR ( decrease of decrease urea decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease antigen processing ) OR ( decrease of decrease urea decrease ))*.
