Example Input:  TRAIL expression on immature CD34DCs or MoDCs was greatly up - regulated after IFN - beta stimulation .
Example Output: IFN - beta

Example Input:  [ ( 3 ) H ] azPC bound recombinant PPARgamma with an affinity ( K ( d ) ( ( app ) ) approximately 40 nm ) that was equivalent to rosiglitazone ( BRL49653 ) , and competition with rosiglitazone showed that binding occurred in the ligand - binding pocket .
Example Output: recombinant PPARgamma

Example Input:  BACKGROUND : Eosinophils are now known to produce a variety of proinflammatory cytokines , although the molecular factors that regulate their production are poorly understood .
Example Output:
proinflammatory cytokines
