RGCs in control
• ipRGCs – Intrinsically photosensitive retinal
ganglion cells (1-3% of RGCs) – The 3rd photoreceptor containing the
photopigment, melanopsin – Synchronize circadian rhythms to the
24-hour dark/light cycle – Regulate pupil size in ambient light
ipRGCs Respond to Blue Light
• Contain the photopigment, melanopsin with peak spectral sensitivity of 460-520 nm
• Blue light absorption by ipRGC melanopsin down-regulates production of melatonin by the pineal gland
• Melatonin suppression results in increased wakefulness and alertness
Light At Night (LAN)
• Increased blue light exposure during the evening meal increases hunger & decreases insulin sensitivity x 2 hours
• Increased light at night exposure significantly elevated BP 4/3 mm Hg in Japanese subjects – 6% increased mortality -10K additional
deaths • Increased LAN also significantly associated
with increased rates of obesity and dyslipidemia independently of melatonin levelsà affects microbiome activity
