To further determine DCs antigen presentation to CD4+T cells, we sort selected uninfected DCs from PBS-injected mice or parasitized DCs from LdWTRFP or LdCen-/-mCherry infected mice recruited to the ear dLN (as shown in S2J Fig) under GL113 or 1A8 treated condition 5d post infection and were incubated with CFSE-labeled Ag-experienced CD4+ T cells for 5d. The gene discussed is CD4; the disease is infection.
