In this study, we therefore analyzed the influence of human CEACAM1 expression on the host immune reaction to C. albicans in a C. albicans colonization and dissemination mouse model mimicking a gastrointestinal tract-derived systemic candidiasis (Koh et al., 2008) and in a systemic model of candidiasis (Jacobsen et al., 2014; Hebecker et al., 2016). The gene discussed is CEACAM1; the disease is candidiasis.
