Focus was given to the pro-resolving protein AnxA1 and its cognate receptor FPR2/ALX, a pathway that has been shown to exert a degree of protection in experimental tuberculosis (Tzelepis et al., 2015; Vanessa et al., 2015), sepsis (Damazo et al., 2005; Gobbetti et al., 2014), pneumococcal pneumonia (Machado et al., 2020; Tavares et al., 2016), and influenza (Schloer et al., 2019). This evidence concerns the gene ANXA1 and influenza.
