New study: visually stunning images showing the location of spike proteins in mice after being injected with tissue from deceased human victims of Covid 19.
One Highlight
The Covid 19 infection was present in the skull, along with the spike protein. Only the spike protein was found in the brain tissue.
'In contrast, only the spike protein was detected in the brain parenchyma. The detected spike protein could either be a residue of a viral infection of the brain that has been cleared or has infiltrated the brain from the cerebral circulation, in either case suggesting that the spike protein could have a long lifetime in the body91. This notion is supported by the observation that spike protein can be detected on patient immune cells more than a year after the infection30, and a recent preprint in medRxiv suggests spike protein’s persistence in plasma samples up to 12 months post-diagnosis31.

Some quotes:
"The lack of evidence for the viral presence and especially viral replication in the brain led to the hypothesis that virus-shed proteins circulating in the bloodstream may promote an inflammatory response independent of direct viral infection of the affected organs, including the brain19,20. Notably, the highly immunogenic spike protein, also used in COVID-19 vaccines21–23, might be a candidate for triggering infection-independent effects."
"Notably, the highly immunogenic spike protein, also used in COVID-19 vaccines, might be a candidate for triggering infection-independent effects."
"The injection of the spike protein alone caused cell death in the brain"
"We found an accumulation of spike protein in the skull marrow niches"
"The human proteomics data showed dysregulation of complement and coagulation cascades, neutrophil-related pathways, and an upregulation of pro-inflammatory proteins."
"Surprisingly, we identified lingering spike protein in the skull samples of a subset of individuals who recovered from COVID-19 and died due to non-COVID-related causes. Thus, accumulation of SARS-CoV-2 and spike protein at the CNS borders can contribute to changes in the brain"
More:
" Furthermore, we observed the presence of spike protein in the skull of deceased long after their COVID-19 infection, suggesting that the spike’s persistence may contribute to long-term neurological symptoms."
" To understand whether the spike protein could be released from the skull marrow niches and induce acute and long-term pathological changes in the brain parenchyma, we injected the spike S1 (N501Y) directly into the skull marrow (Fig. 5A and 5B)35. We found that the spike S1 protein reached the meninges and brain parenchyma 30 minutes after microinjection to the skull (Fig. 5C)."
