The Glymphatic–Meningeal Lymphatic System and Autophagy in ME/CFS and Long COVID: A Mechanistic Perspective 🚨Brain fog, PEM, and crushing fatigue in ME/CFS & LongC0VID may stem from a clogged brain waste-clearance system + broken cellular recycling. Sleep and autophagy are the missing cleanup crew! ➡️This INTERESTING USA mechanistic exploration study proposes that dysfunction of the integrated glymphatic–meningeal lymphatic system (extracellular CSF–ISF waste flushing, mainly during sleep via AQP4 channels and meningeal drainage to cervical nodes) together with impaired autophagy (intracellular lysosomal degradation) contributes to ME/CFS and Long COVID pathophysiology, ➡️These partially overlapping post-( viral-)infectious conditions feature shared symptoms (fatigue, PEM, unrefreshing sleep, brain fog, orthostatic intolerance) and mechanisms including neuroinflammation, mitochondrial dysfunction, reduced cerebral blood flow, and endothelial/BBB issues, ➡️Toxic misfolded proteins and amyloid aggregates (from viral components such as SARSCoV2 spike/EBV, fibrin microclots, oxidative stress, gut dysbiosis/leaky gut, axonal/myelin damage, cell debris, and metabolic stress) accumulate, clog perivascular spaces, mislocalize AQP4, disrupt membranes in a detergent-like manner, and impair selective autophagy subtypes (aggrephagy, mitophagy, ER-phagy, xenophagy, etc), ➡️Circadian/sleep disruption creates bidirectional vicious cycles that worsen clearance failure, ➡️Effects are cell-type specific (neurons, astrocytes, microglia, T cells) and contribute to core features such as PEM, pain, dysautonomia, and cognitive symptoms, ➡️No specific mention of reinfection(s) or vaccines/vaccination impact, ➡️The authors emphasize autophagy regulators, particularly mTORC1, as promising targets, noting that low-dose rapamycin has been linked to reductions in fatigue and post-exertional malaise. They advocate a holistic “cocktail” approach that simultaneously supports both the mechanical (glymphatic–meningeal) and biochemical (autophagy) arms of waste clearance, while cautioning rightfully that, given the heterogeneity of these conditions, the proposed model may apply more strongly to certain patient phenotypes than to others! #heterogeneity ‼️So, according to these authors, persistent buildup of toxic misfolded protein aggregates from failed glymphatic–meningeal lymphatic flushing and autophagy creates a self-reinforcing cycle of neuroinflammation, mitochondrial failure, and clearance collapse that may drive the core neurological and systemic symptoms of ME/CFS and LongC0VID. ‼️Now combining what I’ve learnt from @DavidJoffe64_2 with this study, sleep quality, and timing matter intensely: glymphatic flow and autophagy peak during deep/NREM sleep and fasting periods, so chronic sleep disruption can accelerate waste buildup and symptom flares. Practical angles include prioritizing consistent, high-quality sleep, managing oxidative stress/inflammation (diet, avoiding known triggers), pacing to limit PEM-related metabolic stress, and recognizing that gut health or ongoing inflammatory drivers may feed aggregate production. No proven daily “fix” yet, but the framework supports testing sleep optimization and cautious autophagy-supportive strategies under medical guidance while awaiting targeted trials. #AvoidSars2 #AvoidReinfections #MECFS #LongCOVID #GlymphaticSystem #Autophagy #BrainFog #PEM #SleepDisruption mdpi.com/1422-0067/27/20/935…
