MARCO and infection: Mechanistically, we found that MARCO expression facilitated early accumulation and alternative activation of CD11b+ conventional DC (cDC) in the lung-associated lymph nodes (LALNs), which contributed to the progressive shift of the immune response from Th1 toward Th2 at the priming site (LALNs) and local infection site (lungs) during the efferent phase of cryptococcal infection.
