โข A new hypothesis as to why living organisms need sleep
#neuroscience#biophysics
@real_JackKruse Our theory is valid for all living organisms with a brain. Brain metabolism involves mitochondrial OXPHOS. Mitochondria are found in the cells of nearly every eukaryotic organisms. Myelin and myelin-like sheaths are found in animals with brains.
@annsaada Myelin (rich in lipids) also seems to be an oxygen buffer - see our book chapter from 2023: https://t.co/w3UHBvipOl
Myelin therefore appears to be a proton capacitor, oxygen buffer & site of extramitochondrial OSPHOS. This topic has been extensively studied by Prof. Morelli
@akatzzzzz@annsaada Indeed, there are many implications for medicine and therapy - for example in multiple sclerosis, see our paper from 2023: https://t.co/56JX97s2Lo
@DrJackKruse And also relevant to this discussion: our paper from 2021 -> Myelin sheath and cyanobacterial thylakoids as concentric multilamellar structures with similar bioenergetic properties https://t.co/Oo0fn791Hc
@DrJackKruse The fact that there are animals that don't have myelin (some invertebrates) and do sleep does not contradict our hypothesis. In these animals, a similar biophysical process could be at work forf example in the myelin-like glial cell wrapping around the axons.
@annsaada And in our opinion, the standard model of cellular energy metabolism also needs to be reconsidered.
The new approach is: glucose metabolism is coupled to the pentose phosphate pathway & extra-mitochondrial OXPHOS (especially at the endoplasmic reticulum)
