Exposure to the Functional Bacterial Amyloid Protein Curli Enhances Alpha-Synuclein Agg... - 0 views

  • Our work suggests that protein misfolding and immune activation in neurodegenerative disorders are triggered through cross-seeding by exposure to exogenous microbial amyloids in the nose, mouth and gut.
  • Streptococcus mutans, Staphlococcus aureus, Salmonella enterica, Mycobacterium tuberculosis and others
  • Gene homologs encoding curli were recently determined also in four phyla: Bacteroidetes, Proteobacteria, Firmicutes, and Thermodesulfobacteria

  • changes in the gut microbiota induced by antibiotics alter neuroinflammation and amyloid deposition in a mouse model of AD
  • Our data suggest that amyloid proteins in the microbiota are involved in the origination and maintenance of neurodegenerative disease.
  • exposure to bacteria producing a functional extracellular amyloid protein enhances aggregation of AS in brain neurons in aged rats and in muscle cells in nematodes
  • AS aggregates seed aggregation of tau
  • involvement of the vagus nerve in PD
  • microgliosis, astrogliosis and enhanced expression of IL-6, TLR2 and TNF in the brain following curli exposure suggest the occurrence of an enhanced local sterile inflammatory response to AS in the brain.
  • the immune system in both AD and PD have now been extensively established
  • TLR2 activation through exposure to bacterial amyloid is pathogenic
  •  
    Gut bacteria may play crucial role in systemic inflammation that leads to Alzheimer's and Parkinson's disease.  These amyloid production bacteria trigger systemic inflammation that leads to microglia activation and amyloid in the brain.   More establishment of the gut-brain connection.

Gut microbiota after gastric bypass in human obesity: increased richness and associatio... - 0 views

  •  
    Not that I am proposing gastric bypass for weight loss.  IN my mind that is like a lobotomy for headache.  But, this study shows the link between gut bacteria and obesity.  This study documented an increase in the expression of certain bacteria types in the gut.   This was associated with increase in white adipose tissue gene expression.  Linking directly the gut and fat.

Human gut microbiota in obesity and after gastric bypass - 0 views

  •  
    It is proposed that the balance of bacteria in the gut play a critical role in energy utilization and obesity. This study showed that bypass surgery altered the gut bacteria to favor weight loss: decrease in firmicutes species. But, do we really need gastric bypass to do that? Of course not. Probiotics will do the same.

Karma Km 2500 Wheelchair - 0 views

  •  
    Travel Wheelchairs are usually designed for being as lightweight as is possible for the health of performance or maybe portability. People exactly who travel frequently because of their wheelchairs by means of car or maybe airplane roommates wish a wheelchair is not just lightweight but takes the least number of space doable. Travel information wheelchairs are classified as the most sleek and stylish, lightweight collapsible wheelchairs. The lightest wheelchairs do not need some on the accessories a usual manual wheelchair often have, but almost all models is usually customized to add in items like fold-away footrests in addition to adjustable buttocks. Karma KM 2500 Small Wheel Wheelchair: Karma KM 2500 Small Wheel Wheelchair Specifications: Width 18" Front/Rear Wheels 6" to 14" Seat Width 47cm Seat Depth 40cm Overall Width 66cm Overall Collapsed Width 36cm Armrest Height 21cm Overall Length 90cm Seat Height 47cm Backrest Height 38cm Overall Height 86cm Weight 9.2 k.g. Karma KM 2500 Small Wheel Wheelchair Seat and Back: AEGIS Microbe Shield Approved by the FDA, EPA, EU, etc., bonded anti-microbial barrier upholstery protects from odor, staining and deterioration from bacteria, fungus and other microorganisms. It is a shield for your health. Karma KM 2500 Small Wheel Wheelchair Extended Armrest: By simulating the natural position of arms, the extended armrest design is ergonomic and creates bigger seating space. An Ultra lightweight wheelchair (9.2 kg) with a compact design for either attendant assisted or self propelling users. The use of aircraft-grade aluminium alloy and double cross brace provide this model with outstanding strength and durability. Karma Healthcare KM-2500 Premium Wheelchair is amazingly light and compact transit wheelchair which is ideal for outings and travelers. It folds down to take up virtually no space in the boot of a car and weighs just over 9.2 kg making it easy for anyone to lift into

    Non-medical study finds that probiotics can be used to eliminate pathogenic bacteria.  These probiotics release bactericidal and/or bacteriostatic chemicals that can eradicate/control pathogenic and opportunistic bacteria in aquaculture.  This same logic should be applied to the Gut as well.

Frontiers | Microbiome-Derived Lipopolysaccharide Enriched in the Perinuclear Region of... - 0 views

  • lipopolysaccharides (LPS), either alone or in combination, have indicated that when compared, bacterial LPSs exhibit the strongest induction of pro-inflammatory signaling in human neuronal–glial cells in primary coculture of any single inducer, and different LPS extracts from different gastrointestinal (GI)-tract resident Gram-negative bacteria appeared to have different pro-inflammatory potential
  • powerful inducer of the NF-κB
  • In both neocortex and hippocampus, LPS has been detected to range from a ~7- to ~21-fold increase abundance in AD brain
  • ...15 more annotations...
  • Major Gram-negative bacilli of the human GI-tract, such as the abundant B. fragilis and Escherichia coli (E. coli), are capable of discharging a remarkably complex assortment of pro-inflammatory neurotoxins
  • (i) bacterial amyloids (10, 21); (ii) endotoxins and exotoxins (5, 12); (iii) LPS (12, 18); and (iv) small non-coding RNAs (sncRNAs)
  • integral components of the outer leaflet of the outer membrane of Gram-negative bacteria, LPS
  • LPS, the major molecular component of the outer membrane of Gram-negative bacteria normally serves as a physical barrier providing the bacteria protection from its surroundings
  • LPS is also recognized by the immune system as a marker for the detection of bacterial pathogen invasion and responsible for the development of inflammatory response is perhaps the most potent stimulator and trigger of inflammation known
  • AD-affected brains have remarkably large loads of bacterial-derived toxins compared to controls. The transfer of noxious, pro-inflammatory molecules from the GI-tract microbiome to the CNS may be increasingly important during the course of aging when both the GI-tract and blood–brain barriers become significantly more permeable
  • first evidence of a perinuclear association of LPS with AD brain cell nuclei
  • LPS-mediated stimulation of chronic inflammation, beta-amyloid accumulation, and episodic memory decline in murine models of AD (39, 40) and a biophysical association of LPS with amyloid deposits and blood vessels in human AD patients
  • Strong adherence of LPS to the nuclear periphery has recently been shown to inhibit nuclear maturation and function that may impair or block export of mRNA signals from brain cell nuclei, a highly active organelle with extremely high rates of transcription, mRNA processing, and export into the cytoplasm
  • LPS may be further injurious to the nuclear membrane just as LPS contributes to cerebrovascular endothelial cell membrane injury
  • high intake of dietary fiber is a strong inhibitor of B. fragilis abundance and proliferation in the intact human GI-tract and as such is a potent inhibitor of the neurotoxic B. fragilis-derived amyloids, LPS, enterotoxins, and sncRNAs.
  • GI-tract microbiome-derived LPS may be an important initiator and/or significant contributor to inflammatory degeneration in the AD CNS
  • LPS has been recently localized to the same anatomical regions involved in AD-type neuropathology
  • a known pro-inflammatory transcription factor complex that triggers the expression of pathogenic pathways involved in neurodegenerative inflammation
  • pro-inflammatory amyloids, endo- and exotoxins, LPSs, and sncRNAs but also serve as potent sources of membrane-disrupting agents
