In the lungs, after entering in type II alveolar cells, SARS-CoV-2 infected cells become defective for surfactant production (Ghati et al., 2021) and release cytokines, like IL-8 among others, which in turn activate alveolar macrophages to release IL-1, IL-6, and TNF-, that induce natural killer and dendritic cell differentiation and macrophage M1 polarization, enhancing the proinflammatory response with increased vasodilation causing neutrophil and activated T cell influx from the capillaries into the alveolus, all leading to the cytokine storm (Carcaterra and Caruso, 2021
As a result, initially, a goiter may be formed
In one event where a 71-year-old PD subject was subjected to FMT, improvement in bowel regularity was noted, and tremors disappeared for 2 months after the process (Huang et al., 2019)
It removes an inhibitor (CXXC5), allowing the existing pathway to function normally
