Explanation:
Detailed explanation-1: -Cytokines are essential to the functions of macrophages. They mediate the unleashing of an effective immune response, link innate and adaptive immunity, and influence the macrophage’s microenvironment (4, 7).
Detailed explanation-2: -IL-12 and IL-8 are other cytokines that are produced to enhance the IFN- production which attracts monocytes and T lymphocytes but not neutrophils (in SARS-CoV-2), in order to induce apoptosis and eliminate the infected cells.
Detailed explanation-3: -This cytokine can activate the production of adhesion molecules in endothelial cells and promote the extravasation of neutrophils, monocytes, and others immune cells to be attracted to infection foci.
