EPA for Retinal Neuron DHA Synthesis
This article at a glance
- Photoreceptor cells contain high levels of DHA in their outer light-sensitive segment. Past research had shown that the DHA in photoreceptors was obtained from hepatic synthesis transported via the circulation, as well as from local synthesis in the retinal pigment epithelial cells that support photoreceptor function.
- New research indicates that photoreceptor neurons themselves can also import EPA and convert it to DHA to serve a role in their differentiation and protection from oxidative damage.
