(A) Pr. HCECs were infected with DENV serotypes 1, 2, 3, and 4 at MOI 5 for 48h. Infected cells were subjected to immunostaining using 4G2 antibody, and representative images (n=3) showed the presence of DENV (green) and DAPI (blue). (B) Pr. HCECs were infected with either ZIKV Brazilian strain or DENV3 at MOI: 5 for indicated time points and qRT-PCR was performed to assess the expression of indicated PRRs (TLR3, and RIG-I), inflammatory mediators (IL-1β and TNF-α), and interferon induced genes (ISG15, and OAS2). The values have been presented as mean ± SD, * p<0.05, ** p<0.005, *** p<0.0005, Student’s t-test.
