ATP6V0D2 and infection: To see an involvement of iron in this beneficial effect of RBC supplementation, BMDMs supplemented with opsonized erythrocytes were treated with an iron chelator DFP and then infected with L. donovani. The increased intracellular parasite survival was diminished, and the infection index became equivalent to that of BMDMs without RBC supplementation as well as that of BMDMs with Atp6v0d2 knockdown (Figure 2B).
