Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
response defense » response decrease (Expand search), resource defense (Expand search)
decrease cells » decrease cell (Expand search), decreases cell (Expand search), decrease costs (Expand search)
cells decrease » cells decreases (Expand search), cells increase (Expand search), cells increases (Expand search)
defense during » defenses during (Expand search), defense using (Expand search), defensins during (Expand search)
during objects » using objects (Expand search), cutting objects (Expand search), warping objects (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to decrease (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 cells decrease rate decrease ) OR ( decrease response defense during objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cells decrease rate decrease ) OR ( decrease response defense during objects ))*.
