Following the Trail of Two Proteins
The Stanford team began their investigation by analyzing blood samples from people who had been vaccinated against COVID-19, comparing those who developed myocarditis with those who did not. Two proteins stood out prominently in the blood of those who experienced heart inflammation: CXCL10 and IFN-gamma

Both belong to a category of molecules called cytokines — chemical messengers that immune cells use to communicate with one another. Wu described the pair as operating like a tag team, each playing a distinct but complementary role in driving the inflammatory process that ultimately harms the heart.
