Reposted by BaumjohannLabMarion Pepper @marionpepper.bsky.social · 11/06/2026A decade ago we showed that T-dependent IgM+ memory B cells (MBCs) that express CD80 and CD73 rapidly respond to a secondary Plasmodium infection (Krishnamurty, Immunity, 2016). Since then, post-doc Gretchen Harms Pritchard has been working out the cues that lead to the formation of these cells. ⤵️ 1207
