Ya, feedback loops are everywhere in the body. It’s basically the default for any reaction involving enzymes, which is most of them. But since heart attacks are a clogging of the passage and only result in tissue damage, I could only see this being used afterwards. But with spinal injuries, it maybe a different story.

I’d bet the collagen is there to ensure it’s well received in the heart. As collagen is the main structural protein in the extracellular matrix of a body’s various connective tissues. It could also be a guide to ensure it goes to the right location.

Well, it’s definitely not an antagonist, it’s more the activator of healing if anything. When used for spinal cords, it was “injected as a liquid, the therapy immediately gels into a complex network of nanofibers that mimic the extracellular matrix of the spinal cord. By matching the matrix’s structure, mimicking the motion of biological molecules and incorporating signals for receptors, the synthetic materials are able to communicate with cells.” So the motion is just used to active the tissue repair process.

When it comes to immune cells, Th2 is only found as the primary immune pathway in the heart after cardiac arrest. Beforehand it’s mainly Th1, which is ideal to eliminate forien bacteria as well as viruses. Th2 is primarily for parasite defense, while also resulting in allergies and the regeneration of mucus. This is a contributing factor in being more likely to have a 2nd cardiac arrest after the 1st.

Th2 vs Th1 is a complex relationship, and it’s primarily formed earlier in life. This is why some folks in the 70s used tape worms to cure aliments. It shifted the Th1 response to Th2, providing some relief, yet you had a tape worm in you…
