Fig. 3. Role of endogenous catecholamines in β-agonist insensitivity in RSV-infected mice.

Fig. 3

(a) Effect of RSV infection on plasma epinephrine (EPI) and norepinephrine (NOREPI) levels at day 0 to day 8 after infection (n=12–16 per group). (b) Effect of RSV infection for 2 days (d2; n=8), and RSV infection for 2 days + 100 μM terbutaline (d2/T; n=10) on AFC in adrenalectomized mice (uninfected, Uninf; n=9). Dotted line indicates mean AFC rate in untreated, mock-infected intact mice (n=11). * P<0.05, compared with uninfected, adrenalectomized mice.
