The peak of viral titer was reached later in ChemR23−/− than in WT mice (respectively at day 8 and 10 post-infection), and the titers were up to 100-fold higher in ChemR23−/− than in WT mice (2.7±0.9×106 versus 0.31±0.16×106 PFU/lung at day 8, p<0.05; 5.2±4.5×106 versus 9.1±2.9×104 PFU/lung at day 9, p<0.01; 2.2±2.1×104 versus 170±100 PFU/lung at day 10, p<0.05 respectively). Here, CMKLR1 is linked to infection.
