VDR agonist activity on DENV E protein and VDR expression assessed by immunofluorescence assay. Mock or DENV 2 infected HEK293T/17 cells were treated with 0.01% DMSO or 10 μM of VDR agonists (ZD-1, ZD-2, ZD-3, ZD-5 and ZD-6). After 24 h of treatment, cells were processed under the standard procedure of immunofluorescence assay. DENV E protein (green) and VDR (red) were detected using specific antibodies. Nuclei were stained with DAPI (blue). All the signal was observed under a LSM 800 w Airyscan (ZEISS, Oberkochen, Germany) confocal microscope with 60X magnification.
