Immune response to SARS- CoV-2:
The main aim of both innate and adaptive immune responses against viral
infections, in general, is to block the viral infection and eliminate
the infected cells (Fig. 1). Type I interferons secreted during innate
immunity and neutralizing antibodies produced through adaptive immune
system could prevent the viral infection. However, if the cells got
already infected, then it is the role of the natural killer (NK) cells
as a part of the innate immune system and the cytotoxic CD8 T cells of
the adaptive immune system to eliminate them(25).
