Effect of Poly (I:C) treatment on CHIKV growth. BEAS-2B cells were treated with 4 μg/ml of Poly (I:C) (□) or mock-treated (■) for 1 h, and then infected with CHIKV at MOI 0.01, 1, and 5. At 24, 48, and 72 h p.i., the virus titer in the supernatant was measured by a plaque assay. *P < 0.01 by Student’s unpaired t-test.
