Spike Protein seems to disrupt microtubules in the extracellular fluid, by depolymerization possibly,
Twitter Thread theory by Claudia-Gertrud Krings, @cgkrings, [account suspended, noted 1/12/2022] (45), or due to glyphosate residue. The microtubule problem is not seen in everyone, suggesting to me that there may be a difference in the people - which may be glyphosate incorporated in microtubules instead of glycine.
Glyphosate and glycine are both similarly shaped amino acids which can be used to make proteins, however the synthetic glyphosate has a side group that disrupts function of a receptor opening/protein fold. Molecules of glycine are small and are often found at the point where a protein chain folds to make a receptor opening - add a glyphosate instead and the receptor opening is permanently blocked - dysfunctional.
Why is this bad? Because the end of microtubules typically contain a glycine based area that helps control pathogen risks, (47), and glyphosate disrupts that function. (46)
So the spike protein may be disruptive to microtubules - or it may be that some people have microtubules made with glyphosate that are more prone to malfunction when they are needed for the immune functions, or it may be a combination of both - spike protein disrupts microtubules, particularly those that contain glyphosate.
Microtubules are the scaffolding and cranes of our extracellular and intracellular matrix - which is gelatin like - watery and fluid but with some solidity too. Microtubules direct activity by connecting things where they need to be. If the hook end of the crane is dysfunctional - then nothing can be moved around, such as a pathogen needing to be sent to a white blood cell for removal perhaps. - overview, not my specialty except they are essential for cellular division and growth of all cells.
