One of the most interesting checkpoint inhibitors is the CD200-CD200R1 system (Fig. 1). This checkpoint negatively regulates the immune response with the aim to prevent an excessive inflammatory response to different triggers [19]. Thus, it has been shown to down-modulate TLR7 (single strand RNA virus sensor) in plasmacytoid dendritic cells of a mouse model of coronavirus infection [20] and to down-modulate macrophage activation [21]. Interestingly, the inhibition of CD200-CD200R1 has positive effects on coronavirus infection [19,20,22], restoring IFN production and increasing virus clearance. Checkpoint inhibitors are currently and effectively used as therapeutic agents for a variety of cancers, but have only minimally been studied in human infectious diseases, although their function was clearly defined using the murine model of LCMV infection. A CD200-Fc fusion protein has been successfully used in experimental settings [21] and trials on inhibitory antibody targeting of CD200 has been tested for the treatment of human cancer [19], thus suggesting the intriguing possibility to use currently available checkpoint inhibitors for the treatment of CoViD-19. A trial with another checkpoint inhibitor, anti-PD1, is also ongoing in CoViD-19 patients."}

This checkpoint negatively regulates the immune response with the aim to prevent an excessive inflammatory response to different triggers [19]. Thus, it has been shown to down-modulate TLR7 (single strand RNA virus sensor) in plasmacytoid dendritic cells of a mouse model of coronavirus infection [20] and to down-modulate macrophage activation [21]. Interestingly, the inhibition of CD200-CD200R1 has positive effects on coronavirus infection [19,20,22], restoring IFN production and increasing virus clearance. Checkpoint inhibitors are currently and effectively used as therapeutic agents for a variety of cancers, but have only minimally been studied in human infectious diseases, although their function was clearly defined using the murine model of LCMV infection. A CD200-Fc fusion protein has been successfully used in experimental settings [21] and trials on inhibitory antibody targeting of CD200 has been tested for the treatment of human cancer [19], thus suggesting the intriguing possibility to use currently available checkpoint inhibitors for the treatment of CoViD-19. A trial with another checkpoint inhibitor, anti-PD1, is also ongoing in CoViD-19 patients."}
