If it's on your mind and it has to do with multiple sclerosis in any way, post it here.

One wonders if this substance is low in MS patients.

The pancreas provides a potential drug candidate for brain disease

Scientists conducting a mouse study have found that a substance secreted by the pancreas can promote the regeneration of the protective nerve coating that is damaged in multiple sclerosis (MS).

The study, titled “Peripherally derived FGF21 promotes remyelination in the central nervous system,' was published in The Journal of Clinical Investigation.

The research shows that the substance, fibroblast growth factor 21, or FGF21, promotes remyelination in mice and may be a promising key molecule for treating demyelinating disease. Remyelination is the renewal of the myelin sheath that protects the central nervous system.

In normal development, oligodendrocyte precursor cells (OPCs) differentiate into oligodendrocytes, which are required for myelination. OPCs will proliferate around the lesions of demyelination after injury and contribute to spontaneous remyelination, but the molecular mechanism of OPCs proliferation is not fully clarified. Osaka University Associate Professor, Rieko Muramatsu focused on the blood leakage around demyelinating lesion. "Factors in the blood cannot reach the normal brain because the central nervous system has a blood-brain barrier. In demyelination diseases like multiple sclerosis, the blood-brain barrier around the lesion is disrupted," she said.

Muramatsu suspected that with the breach, factors from peripheral organs secreted into the blood could now reach the brain.

To test her hypothesis, "We disrupted the vascular barrier and myelin structures in mice by injecting Lysophosphatidylcholine (LPC). We looked for circulating factors that promote OPCs proliferation and found FGF21 as a candidate," she explained.

FGF21 is secreted by the pancreas and it is known to regulate metabolism, “but its effects on OPC proliferation were unexpected," said Muramatsu.

The results suggest that FGF21 has therapeutic potential for demyelinating diseases. FGF21 analogs are already being used for clinical studies on diabetes, which means its development for remyelination could go faster than had it been an untested compound.

"There are many drugs that inhibit demyelination, but none that promote remyelination. FGF21 is a new candidate that deserves more testing. The most important finding is that we show the peripheral milieu promotes central nervous system remyelination."
I know someone with both Juvenile Diabetes and MS. I begin to wonder if MS is one of many things that can go wrong with the pancreas.
