Extended Data Fig. 3: Gating strategy used for sorting of CD4 T cells and plasma cells.

CD45⁺ live cells were gated for lymphocytes, and then singlets. CD4 T cells were sorted from this singlet population as CD3⁺ CD19 negative, CD4⁺ CD8 negative. Plasma cells were sorted from this singlet population as CD3 negative, CD27⁺ CD38⁺.
