One of the critical symptoms of SARS-CoV-2 infection is lymphopenia. Lymphopenia is a condition in which patients exhibit reduced levels of white blood cells called lymphocytes. Lymphocytes are the fundamental defense cells of our adaptive immune system. They consist of natural killer cells, T cells, and B cells.
Currently, there are several theories surrounding SARS-CoV-2-induced lymphopenia and how the virus can attack lymphocytes in the absence of ACE2 receptors. However, this paper represents real progress in our understanding of the scope of SARS-CoV-2 infections and provides an interesting theory about how SARS-CoV-2-induced lymphopenia occurs. As research continues to develop, it will be interesting to discover exactly how this virus attacks and dismantles one of our key defense systems.
