CD19 and infection: Interestingly, despite not being significantly enriched in a GO category because of the limited gene number, cluster #5 includes multiple cellular markers of B cells (e.g. Cd19, Cd79a, etc.)and mast cells (e.g. Gata2, Cma1, etc.)(S2B Fig), indicating that these cell types are proportionally less abundant following L. majorWT infection only.
