Uptake of cyanosine and rose bengal by mosquito cells of the C6/36 line and their photosensitivity in vitro. The insect cells were exposed to both dyes overnight and illuminated with white light under conditions similar to those described for mammalian and Leishmania cells [10–12, 22]. Images were captured first under differential interference (DIF) [A] and then under the filter sets for DAPI and Texas red [B]. [C] Chemical structure of cyanosione and rose Bengal. Uptake of both dyes by the cells after incubation in the dark overnight (Dark, A2-3, B2-3) and cellular disintegration after light exposure for 4 h (Light, A2-3, B2-3) in contrast to the untreated controls (Dark and Light, A1, B1).
