Seems important, and I really like the concept. if I follow correctly interepitope competition is permissive whereas intra kills low affinity cells.

Following from Maria Lafaille's discoveries of a couple of days ago, we found that BCL2, BCLXL or BCLW dominates over MCL1 in the survival of IgE PC, which localise atypically for long-lived cells.

Online now: Long-lived IgE plasma cells that reside in the spleen contribute to the persistence of the IgE response
Long-lived IgE plasma cells that reside in the spleen contribute to the persistence of the IgE response
Allergies can persist even in the absence of allergen exposure. Miranda-Waldetario et al. find that IgE-producing plasma cells mature, acquire survival adaptations, and persist for extended periods of time in the spleen and bone marrow, secreting antibodies that can trigger anaphylaxis.

Team, this piece is great if you're interested in Abs! TLDR: GC-derived ASC maintain a proliferative burst post-differentiation proportional to affinity/help to explain overrepresentation of high affinity in PC despite differentiation from all affinities.
