COVID-19 and innate immunity

Abstract

The human body fights many pathogens in the environment with different methods. One of them is immunity. There are innate and acquired immunities. The purpose of innate immunity is to maintain the body's own and biological individuality, to identify and destroy foreign substances and cells, including pathogenic bacteria and viruses, as well as tumor cells that have grown in the body. The innate immune response accomplishes this by means of myeloid lineage cells that have no strict specificity for antigens, do not elicit a clonal response, and have no memory for primary contact with a foreign agent. Acquired immunity has the ability to recognize and respond to individual antigens, characterized by a clonal response in which lymphoid cells are also involved. He has an immunological memory. The body responds to COVID-19 invasion with both innate and acquired immunity. This article reviews the innate immune response to the invasion of COVID-19 in the body.
