Similar findings were noted in the study by Acosta-Ampudia et al., where a pro-inflammatory state was observed in patients with PASC characterized by up-regulated IFN-α, TNF-a, granulocyte colony-stimulating factor (G-CSF), IL-17A, IL-6, IL-1β, and IL-13, whereas IP-10 was decreased [134]. Here, CXCL10 is linked to long COVID-19.
