Abstract
In prion diseases, a major issue in therapeutic research is the variability of the effect between strains. Stimulated by the report of an antiprion effect in a scrapie model and by ongoing international clinical trials using doxycycline, we studied the efficacy of cyclines against the propagation of human prions.
First, we successfully propagated various Creutzfeldt-Jakob disease isolates (sporadic, variant and iatrogenic CJD) in neuronal cultures
expressing the human prion protein.
Then, we found that doxycycline was the most effective compound, with important variations between isolates.
Isolates from sporadic CJD, the most common form of prion diseases showed the highest sensitivity.

Those educated in a time when Goodman and Gilman's Textbook of Pharmacology

are now up against the ropes and being Pummeled by major changes in
the conventional wisdom of the Reach and Grasp of a pharmaceutical
which was taught to act by a Ribosomal Mechanism.
The above cited references challenge us to embrace new and heretofore
unimagined Pharmaceutical Mechanisms of Medicinal Chemistry in the human host.
Proteins - Pathologic merely because of Misfolding leads to 3 dimensional conformations..
-
Prions for which Pruisner campaigned for his own Nobel Prize with the promise
that such entities were Independent of DNA..
Did Dr. Stanley Pruisner know more than he was telling us in his acceptance speech
in Stockholm?
Is there Now
an "Explainer in Chief" to render the Realities of Doxycycline and DNA-independent Pathological Prions
to those of us here on the forum?
We need short Anglo Saxon Words free of Jargon to resolve these quandries...............
Who could fill the Bill??

Re: Doxycycline stops Prion Protein Infections
In awarding research that may otherwise go unnoticed, prize juries also have an important role in sending a message to the scientific community about the importance of a particular research area.
Stanley Prusiner's discovery that prions are the causal agent of scrapie, mad cow disease and Creutzfeldt–Jakob disease was not widely accepted until he won the Lasker Award and the Nobel Prize for his work.
Robin Warren and Barry Marshall's discovery that Helicobacter pylori cause gastritis and stomach ulcers was largely ignored by the medical community,
who could not accept that a simple bacterium could be the cause of peptic ulcers.
However, the fact that Marshall won a Lasker and a John Scott Award in 1995 and a Gairdner Foundation International Award in 1996, and shared the 1994 Warren Alpert Prize and the 1997 Ehrlich Prize with Warren, helped to make their discovery more acceptable. “It was a good idea and moderate methodology, but the perspective behind it is enormous,” explained Fleckenstein.
“Sometimes, you want to show a bit of courage.”
Jury members also showed courage in awarding the 2005 Ehrlich Prize, worth euro100,000, to Ian Wilmut for his cloning experiments, a decision that was vehemently criticized in Germany by opponents of cloning and stem-cell research.

Re: Doxycycline stops Prion Protein Infections
Not everyone thinks prions are causative. But rather a result of a stealth bacterial infection. So Nobel or not, this could explain why doxy works.
Re: Doxycycline stops Prion Protein Infections
Yes lou. Spirochetes have at least 3 or 4 proteins described as ""prion- like"" found so far. Their recombinations in theory are infinite.
Their recombinations mostly reside in the skin.

Abstract
Spiroplasma biofilm formation explains the role of these wall-less bacteria in the pathogenesis of transmissible spongiform encephalopathies (TSEs). Spiroplasma embedded in the biofilm polysaccharide matrix are markedly resistant to physical and chemical treatment, simulating the biologic properties of the TSE agent. Microcolonies of spiroplasma embedded in biofilm bound to clay are the likely mechanism of lateral transmission of scrapie in sheep and chronic wasting disease in deer via soil ingestion. Spiroplasma in biofilm bound to the stainless steel of surgical instruments may also cause iatrogenic transmission of Creutzfeldt-Jakob disease. Sessile spiroplasma in biofilm attach to the surface by curli-like fibrils, a functional amyloid that is important for spiroplasma entering cells.
Curli fibers have been shown to interact with host proteins and initiate formation of a potentially toxic amyloid that multiplies by self-assembly.
In TSE, this mechanism may explain how spiroplasma trigger the formation of prion amyloid. This possibility is supported by experiments that show spiroplasma produce α-synuclein in mammalian tissue cultures. The data linking spiroplasma to neurodegenerative diseases provide a rationale for developing diagnostic tests for TSE based on the presence of spiroplasma-specific proteins or nucleic acid. Research efforts should focus on this bacterium for development of therapeutic regimens for Creutzfeldt-Jakob disease.

Could the combination of Doxy with other do the job? No it will not stop the immune suppression. For that they need their stem cells after killing all they can to raise the gates of the immune systems the stealth has destroyed.

Direct assessment in bacteria of prionoid propagation and phenotype selection by Hsp70 chaperone.

Abstract
Protein amyloid aggregates epigenetically determine either advantageous or proteinopathic phenotypes. Prions are infectious amyloidogenic proteins, whereas prionoids lack infectivity but spread from mother to daughter cells.
While prion amyloidosis has been studied in yeast and mammalian cells models, the dynamics of transmission of an amyloid proteinopathy has not been addressed yet in bacteria.
Using time-lapse microscopy and a microfluidic set-up, we have assessed in Escherichia coli the vertical transmission of the amyloidosis caused by the synthetic bacterial model prionoid RepA-WH1 at single cell resolution within their lineage context.
We identify in vivo the co-existence of two strain-like types of amyloid aggregates
within a genetically identical population and a controlled homogeneous environment.
The amyloids are either toxic globular particles or single comet-shaped aggregates that split during cytokinesis and exhibit milder toxicity. Both segregate and propagate in sub-lineages, yet show interconversion. ClpB (Hsp104) chaperone, key for spreading of yeast prions, has no effect on the dynamics of the two RepA-WH1 aggregates.
However, the propagation of the comet-like species is DnaK (Hsp70)-dependent. The bacterial RepA-WH1 prionoid thus provides key qualitative and quantitative clues on the biology of intracellular amyloid proteinopathies.
