Below is an excerpt from an article at Stephanie Seneff’s blog. Stephanie is an MIT Senior Research Scientist. The article is chalked full of very informative information but I wanted to pull out this part about the spike protein I’ve been hearing so much on since these experimental vax jabs have come out. Please visit her site at the below link and read the whole article.
The Spike Protein is Toxic
The COVID-19 vaccines are all based on supplying genetic code to produce the spike protein that is the main constituent of the SARS-CoV-2 protein cage that encloses its RNA contents. Both the DNA vector and the RNA vaccines induce the vaccine-infected cell to manufacture many copies of the spike protein according to the code. Through experimentation, researchers have determined that the spike protein is toxic even when introduced all by itself. In a revealing experiment, researchers injected spike protein into hamsters, and found that it was taken up by endothelial cells lining the blood vessels, via ACE2 receptors [10]. This caused a downregulation of ACE2, which had significant effects on the metabolic policy in the cells. In particular, it inhibited the synthesis of mitochondria, and caused the existing mitochondria to fragment. Mitochondria are the organelles in the cell that produce large quantities of ATP (the energy currency of cells) by oxidizing nutrients, while consuming oxygen and producing water and carbon dioxide. The spike protein reduced the production of ATP by mitochondria and increased glycolysis — the alternative, much less efficient, way to produce ATP without using oxygen. This metabolic change towards getting energy through glycolysis is a characteristic feature of cancer cells and of neurons in neurodegenerative diseases such as Alzheimer’s.
In another experiment, researchers showed that spike protein can cross the blood-brain barrier in mice and be taken up by neurons throughout the brain [11]. This too is likely mediated by ACE2 receptors (which neurons also produce). These same researchers also showed that spike protein administered in the nose was able to reach the brain by traveling along the olfactory nerve. When they induced inflammation in the brain through exposure to lipopolysaccharide (LPS), they saw an increased uptake of spike protein into the brain, which they hypothesized was caused by increased leakiness in the barrier. As you will see, these points become important when we later consider what happens following a SARS-CoV-2 vaccine, which is designed to induce inflammation.
Many people suffering from COVID-19 have experienced symptoms characteristic of the central nervous system such as headache, nausea, dizziness, fatal brain blood clots and encephalitis. In an advanced 3D microfluid model of the human BBB, researchers in the United States showed that the spike protein by itself disrupts the blood brain barrier by inducing an inflammatory state, and they proposed that this could be the source of such symptoms [12].
A published preprint found widespread expression of ACE2 in many parts of the brain. ACE2 was expressed in astrocytes, pericytes (cells that wrap around the endothelial cells lining capillary walls) and in endothelial cells — and all of these are key components of the blood-brain barrier [13]. Perhaps of even greater concern is that ACE2 was highly expressed in the substantia nigra, a brain-stem nucleus where damaged dopaminergic neurons lead to Parkinson’s disease.
