Inhibition of p38MAPK decreases viral yield^a

Treatment	Viral yield (PFU, 107)b at:
	18 h	24 h	28 h	32 h
DMSO	6.5 ± 0.3	12 ± 1	21 ± 1	17 ± 1
SB203580	6.0 ± 0.3	8.0 ± 0.4	8.9 ± 0.4	7.7 ± 0.4

^aCells (5 × 10⁶) were pretreated with 30 μM SB203580 or DMSO for 1 h and infected with wt HSV-1 in the continuous presence of SB203580 or DMSO. 

^bViral yields were determined at 18, 24, 28, and 32 h postinfection. Each value represents the mean ± standard deviation from three independent experiments, and in each experiment triplicate determinations were performed.
