ABSTRACT
Given the appearance of a "new virus" in the of Wuhan city, China, called SARSCoV- 2, which causes the well-known severe acute respiratory syndrome (COVID- 19), many scientists are trying to find a solution against the virus that has caused a pandemic. In this search, a transmembrane glycoprotein called dipeptidyl peptidase 4 or DPP-4 was found present on the surface of different types of cells and a target in MERS-Co-V infection, which opens hope by suspecting that DPP- 4 can be a target in different coronaviruses by serving as a therapeutic strategy. Added to this, there are results that find elevated DPP-4 in patients with severe complications from COVID-19, which may be a possible marker of severity. However, there is still little emphasis on the identification and association of this glycoprotein with COVID-19. To this effect, a bibliographic review was carried out on the most significant aspects of Dipeptidyl Peptidase 4 and its function against COVID-19.
