When we infected BMDM with live pathogenic and heat-killed M. tb, it was observed that both live and heat-killed M. tb had Cor1 recruited to the respective phagosomes at the 0-h time point but only live M. tb containing phagosomes could retain the Cor1 coat after 3 h of infection and heat-killed M. tb containing phagosomes fused with lysosomes as it failed to retain the Cor1 coat around the phagosome (Figure 1B). This evidence concerns the gene SYCP3 and infection.
