Fluorescent light exposure inhibits the constitutive internalization of 5-HT3A/BBS receptors. BTX/488 labeled surface 5-HT3A/BBS receptors stably expressed in HEK-293 cells were exposed to 9.73 mW/cm2 of ∼488 nm light generated from a 100 W mercury arc lamp (a) or 157.5 mW/cm2 of ∼488 nm light from an argon laser (b) every minute for 30 min at 37 °C. Representative images of cells are shown at 0, 10, 20, and 30 min. After 30 min at 37 °C surrounding cells that were not exposed to light from a mercury arc lamp (c) or an argon laser (d) are shown. Arrows indicate internal puncta. Scale bar=10 μm.
