SDC1 and infection: Further, those B cell clusters significantly and specifically enriched in bone marrow of the PZQ-primed offspring (clusters C57, C66, C77 and C86), however, all fall within the central grouping of the heatmap, and are notable for high levels of IgD expression, as well as increased CD138, indicative together of an increased maturation profile, and therefore could be involved in the preparedness towards infection evidenced during cognate infection.
