Comparative Clonal Composition of the Secondary Response to HA, Related to Figure 5
(A) Clonal sharing between footpads in fate-mapped and non-fate-mapped secondary GC B cells. S1pr2-Tomato mice were infected with influenza then boosted in both hind footpads with recombinant HA as described in Figure 5. Figures show the clonal composition of non-fate-mapped GC B cells (left panel) and fate-mapped MBC, PB, and GC B cells (right panel) in the two pLNs at 6 days after boost. Clones found in both left and right pLN are highlighted in blue. Data correspond to mice 3 and 4 from Figures 5A and S4A.
(B) Clonal maps showing distribution of clones across different compartments. Data as in Figure 5C but analyzed at day 9 post boost. ∗MBCs and PBs for mouse 6 were not analyzed due to the very low number of cells.
(C) Quantification of clonal diversity and dominance for the data in (B).
(D) Average VH mutations per clone in fate-mapped and non-fate-mapped GC B cells from (B). P value is for Mann-Whittney U test.
