ABSTRACT
Neutrophils play an important role in infectious diseases by clearing pathogens in the early stages of the disease and damaging the surrounding tissues along with the disease progress. Low-density neutrophils (LDNs) are a crucial and distinct subpopulation of neutrophils. They are a mixture of activated and degranulated normal mature neutrophils and a considerable number of immature neutrophils prematurely released from the bone marrow. Additionally, they may be involved in the occurrence and development of diseases through the changes in phagocytosis, the generation of reactive oxygen species (ROS), the enhancement of the ability to produce neutrophils extracellular traps and immunosuppression. We summarizes the role of LDNs in the pathogenesis and their correlation with the severity of infectious diseases such as COVID-19, severe fever with thrombocytopenia syndrome (SFTS), AIDS, and tuberculosis.

ABSTRACT
Due to the resurgence of COVID-19, understanding the biology of SARS-CoV-2 is an opportunity to develop adjuvant therapies that could target its pathobiology and lessen the severity of the COVID-19 infection so that our patients could survive. This commentary serves to accomplish this by using published morphoproteomic findings with data mining of the medical literature to define the pathobiology of COVID-19 pneumonitis and provide combinatorial and relatively non-toxic adjuvant therapies that have been successful against this viral infection.
