Lior Shaltiel, CEO of NurExone, is addressing the unmet needs of those with spinal cord injuries, as current therapies only treat symptoms and do not regenerate damaged nerves from accidents or disease. The NurExone technology aims to stimulate nerve growth by targeting a protein that inhibits cell proliferation. Using exosomes, which are secreted by cells, to deliver the drug in a localized manner is possible because of the ability of the exosomes to home in on damaged tissues and cross the blood-brain barrier.

Lior explains, "At the moment, the medicine can only treat it by treating the symptoms. There are a few attempts to try to regenerate the nerves that are broken and to have the reconnection of the spinal cord injury or any damage in the central nervous system. And this is a huge challenge for medicine, so far not solved. And when we solve it, we prepare to answer and give hope to so many patients, not only in spinal cord injury, but also in other injuries, such as traumatic brain injury, optic nerve, and ophthalmology. So many nerves that we have so far not been able to restore the function after the damage."

"So traumatic, meaning we are talking about injury, the acute phase of a disease or illness. In most cases, let's say, spinal cord injury is due to injury, car accidents, or sports accidents. But, for example, ophthalmology, glaucoma, which is a chronic disease, can also cause damage to the optic nerve that cannot be restored. So it can be due to another illness, as a side effect of the illness, or due to injury."

"So we discussed the RNA. This is one part of the technology here. Second, the technology of using our natural transmitter in our body, which is how cells communicate with each other, is called exosomes. Exosomes are tiny vesicles secreted from cells with tiny envelopes that a healthy tissue sends to a damaged tissue, a cell that is affected, or a cell that doesn't feel good. And when we understand this mechanism, we can use those exosomes as a drug delivery system."
