Letter from Pr Henri Joyeux no 142
In this letter, to facilitate understanding, we have devised a dialogue between James Parkinson and Alois Alzheimer. They interview Professor Jean-Bernard Fourtillan who discovered the sleep hormone, as well as sleep-wake regulation.
After the detailed presentation, by James Parkinson and Alois Alzheimer themselves, of the diseases named after them, here is a first fictional interview conducted by James and Alois. They talk to Professor Jean-Bernard Fourtillan, who discovered the sleep hormone and the sleep-wake regulation.
These two neurodegenerative diseases share the same cause which can affect different regions of the brain: the secretions of the 3 pineal hormones, Melatonin, 6-Methoxyharmalan and Valentonin are insufficient.
Pr Jean-Bernard Fourtillan explains in detail the action of the 3 hormones produced by the small pineal gland at the centre of the brain, also known as epiphysis. Discharged into the blood stream during the night, they are distributed throughout the body and make their way to their sites of action. Melatonin protects all cells, more specifically the nerve cells (neurons), by reducing oxygenated free radicals, which prevents their destruction via radical oxidation processes.
The other 2 pineal hormones, Valentonin (VLT) and 6-Methoxyharmalan (6-MH), modulate the responses of 2 types of specific receptors:
– the receptors of the neurotransmitters located on synapses, junction points between the neurons. They amplify (VLT) or reduce (6-MH) the transmission of nerve impulses in these neurons;
– and the hormone receptors (receptors of liberins or stimulines) located on the endocrine glands (hypophysis, etc.). VLT reduces hormonal secretions during the night, unlike 6-MH, which reduces them during the day.
Thanks to their competing actions, in waking or sleeping mode, VLT and 6-MH totally regulate the life of our body 24 hours a day.
The discovery of these regulation mechanisms helps explain the effectiveness of the substitution treatment which provides the 3 hormones of the sleep-wake regulation, in the prevention and treatment of neurological disorders.
Letter from Pr Henri Joyeux no 138
In his letter to all those affected by Alzheimer’s disease, Pr Henri Joyeux gets the father of the disease himself to talk. How did he discover and describe it? Why is it named after him? Why are all the treatments proposed to patients, even at the onset of the disease, completely ineffective? The recent controversy about reimbursements is significant: experts are asking to put a stop to the reimbursement of useless and costly drugs, and the French Minister of health wants to maintain them to avoid losing the votes of the elderly.
Alois Alzheimer presents the discovery made in France by Pr Jean-Bernard Fourtillan, a professor of medicinal chemistry. It relates to the regulation of the Sleep-Wake system, which is the responsibility of the pineal gland, aka epiphysis. The deregulation of this system causes all the disorders of the disease. Incredible therapeutic prospects for tens of millions of people worldwide.
