New Delhi, Mar 25 (PTI) Altering the levels of metabolites in the Kynurenine pathway, responsible for regulating eye colour, has been found to impact retinal health, according to a new study in flies.

The study conducted by Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG) in Germany investigated the classic Drosophila genes cinnabar, cardinal, white, and scarlet, named due to their role in eye colour pigmentation and in particular the formation of the brown pigment of the fly eye.

These genes encode components of the kynurenine pathway, a metabolic pathway responsible for regulating eye colour, among other various biological processes. Changes in this pathway can impact the health of the brain, including the retina.
