Perhaps you should try some spelling variations:
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease treg » decrease the (Expand search), decrease their (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
treg basic » are basic (Expand search), treaty basic (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 in decrease _ decrease ) OR ( decrease lipid decrease treg basic ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease _ decrease ) OR ( decrease lipid decrease treg basic ))*.
