Alternatively activated macrophages regulate immune responses in the granulomas around S. mansoni eggs. These cells are an important source of retinoic acid and enhance the differentiation of Foxp3+ T cell differentiation (see Broadhurst et al., doi:10.1371/journal.ppat.1002883). By intravital confocal imaging, autofluorescent eggs are observed in red, hepatocyte nuclei in blue, and CX3CR1+ macrophages in green.
