The study found that two immune signaling proteins, CXCL10 and IFN-gamma, appear to play a central role. Researchers observed that certain immune cells exposed to the vaccine produced these inflammatory signals, which then appeared to trigger immune activity that could affect heart tissue. Their results in lab experiments, mice, and heart-like tissue models suggested that this inflammatory chain may help explain the rare cases of heart inflammation seen after vaccination.
