After infection with a YFP-expressing Af293-derived strain, the normalized number of macrophages recruited to and interacting with injected spores was not significantly different between rac2−/− and rac2+/− or rac2+/+ larvae at either 1 dpi or 2 dpi, demonstrating that Rac2 is not required for macrophage migration to the site of A. fumigatus infection (Fig. 2A). Here, RAC2 is linked to infection.
