The overrepresented transcripts in Charles River mice include Galectin-9 (LGALS9), which is an important immune signaling molecule (Merani et al., 2015), and Basigin (bsg), a cell surface receptor whose expression is required for infection of RBCs by the human malaria parasite P. falciparum (Crosnier et al., 2011). Here, LGALS9 is linked to infection.
