COVID ‘Spike Protein’ Enters the Brain: Nature Neuroscience Article

Study shows the S1 protein of SARS-CoV-2 crosses the blood-brain barrier in mice.

A publication in Nature Neuroscience journal concludes that intravenously injected spike proteins do cross the blood-brain barrier (BBB) and are “taken up by brain regions” in animal studies.

The goal of the study was to assess whether the COVID spike protein can indeed cross the BBB.

As explained by the study’s authors, COVID-19 is associated with a host of symptoms that relate to the central nervous system (CNS), “including loss of taste and smell, headaches, twitching, seizures, confusion, vision impairment, nerve pain, dizziness, impaired consciousness, nausea and vomiting, hemiplegia, ataxia, stroke and cerebral hemorrhage.”

The authors hypothesized that some of the symptoms of COVID are “due to direct actions of the virus on the CNS” and “could be a result of virus or viral proteins having entered the brain.”

The authors verify that the COVID spike protein not only crosses the BBB, but enters brain tissue and is “sequestered” by brain cells.

“In this study, we show that I-S1 readily crossed the murine BBB, entered the parenchymal tissue of the brain,” write the authors, “and, to a lesser degree, was sequestered by brain endothelial cells and associated with the brain capillary glycocalyx.”

But COVID mRNA “vaccines” are designed to instruct the human body to make spike proteins too.

The Centers for Disease Control and Prevention (CDC) explains that COVID mRNA vaccines—such as those manufactured by Pfizer and Moderna—work by forcing the body to produce spike proteins within its own cells.

The CDC website explains:

“COVID-19 mRNA vaccines give instructions for our cells to make a harmless piece of what is called the ‘spike protein.’ The spike protein is found on the surface of the virus that causes COVID-19.”

As American Faith has reported, vaccine researcher Dr. Byram Bridle revealed that the spike protein in COVID vaccines is a “toxin” that “can cause damage in our body if it gets into circulation.”

World-renowned Professor of Medicine and board-certified cardiologist Dr. Peter McCullough said in an interview that “[b]ased on the safety data now” he “can no longer recommend” COVID vaccines. McCullough noted that the vaccines are not only deadly but are also defunct because the vaccines only target the original COVID spike protein, which is now “extinct.” “Patients are getting vaccinated to something that doesn’t even exist anymore,” said Dr. McCullough, adding “That Wuhan spike protein is gone.”
