The Eyelash Gecko

Blog vol 4.24. The Eyelash Gecko


One of my son’s friends got a gecko for his birthday. It is really cool; it is a reptile after all. The thing that I am amazed at is its eyes (surprise!). It is called the Crested Gecko, Correlophus ciliatus, with the cilia part of the name coming from the Latin word for eyelashes.


So I got on the web and did some research. This gecko is a native of New Caledonia, a group of islands in the southwest Pacific. They live in the canopy of the rain forests and can live to be 5 to 10 years old in the wild and about 5 years longer in a terrarium. Crested Geckos can grow to be 10 to 15 cm in length with half of that being their tails. They have a prehensile tail that can grab onto branches or fingers, but one must be careful with the tail as it can break off and, unfortunately, it does not grow back.

 

Among the most distinctive features of these geckos are the hair-like spikes above the eyes which greatly resemble eyelashes. They also have two rows of spines that run from the sides of their wedge-shaped head to the base of their tail. Their padded feet have tiny setae, hundreds of them, which increase surface area and allow them to even climb vertical panes of glass.

The part about their eyes is crazy because these creatures have no eyelids. They have a thin, transparent layer called a nictitating membrane which can be drawn across to protect and moisten the eye. What is really endearing is that they often just sit and lick their eyeballs, especially after eating. Their tongue is very long and soft with a widened spatula-like tip. The nictitating membrane keeps each eye moist, and the geckos use their tongues to clear away debris.


The crested gecko is primarily nocturnal. In the wild, it spends much of the night foraging in shrubs in lower portions of the rainforest canopy. It is also an omnivore, feeding on fruit, nectar, pollen, and a variety of insects.  It spends the day resting near the forest floor where it is cooler and less sunny. (Read more here).


The little fellow that we are getting to know goes by the fierce name of Draco, all he needs is fire-breathing creature powers and then watch out.

The good doctor take a deeper look at how gut health is connected to eye tissues.

Blog vol 6.40. The Gut and the Eyes. One of my biggest jobs is to keep abreast of new research and advances in eye health. Most recently, we have seen new stem cell research, gene therapies, as well as new drugs for dry and wet macular degeneration. In January of this year, there was an article in the journal, Cell Death and Disease, that looked at cell apoptosis, specifically with the photoreceptors of the eye. (Read the article here ). Apoptosis is the genetic programming of deliberate and constructive cell death, allowing for the maintenance of healthy structures and systems in the body. Some estimates have the body replacing 50 to 70 billion cells daily by this process. Necrosis, on the other hand, is unplanned cell death caused by injury, toxins, or other negative outside factors; this causes inflammation and disrupts the body’s balance of things. There are stressors that speed up cell turnover. The study looked at photoreceptors in the retina and were able to demonstrate cellular recovery, even in late stages of apoptosis, recovery not breakdown. When certain stressors were reduced, by working with the mitochondria, there was recovery of the photoreceptor cells. How? Mitophagy, the mitochondria’s own process of programmed breaking down and then repurposing the recycled components for new ones. This mitochondrial repair helps to reverse the sequence of apoptosis for the photoreceptors. Mitochondria, how cool. How is this helpful for our eyes? Conditions like retinitis pigmentosa or macular degeneration directly involve the photoreceptors and may be slowed or reversed by helping the mitochondria. So, let’s take care of those mitochondria. There is some evidence for nutritional support for the mitochondrial system. The nutrient, Urolithin A (UA), which is a compound made in our gut from fiber found in pomegranates, berries, and nuts is the only clinically proven substance known to trigger mitophagy, made in the gut no less. Vitamin B3 is critical for mitochondria function, however vitamin B3 based supplements are still to be clinically tested for their support of cell recovery. Nutrients Coenzyme Q10 and L-carnitine are known to help the mitochondria generate energy, and interestingly, infrared light therapy has also been shown to benefit mitochondrial function. Again, food for thought. The gut and its function needs a lot of research. How do probiotics and nutrient precursors affect eye tissues? It is so interesting that the gut can be a factor in eye health. Maybe adding Urolithin A as a supplement is wise, along with the antioxidants in Lutein and Zeaxanthin we use to combat photoreceptor degeneration. Will keep you posted on any new developments.
