Figure 2. Kappa opioid induces activation of pqsABCDE synergistically with HHQ.

Figure 2

Luminescence normalized to cell density was measured dynamically in the reporter strain ΔPqsA/pqsA::luxCDABE grown in 0.1xTY in the presence of (A) varying doses of U-50,488; (B) varying doses of HHQ; (C) varying doses of U-50,488+200 µM HHQ; and (D) varying doses of PQS.
