Covey J Immunol June 1, 2021, 206 (11) 2552-2565; DOI: https://doi.org/10.4049/jimmunol.2001074 Key Points mRNA stability is critical for optimal CD40L expression and TFH cell function. Decreased CD40L results in a loss of GL7+ GC B cells and a disorganized GC. GC B cell differentiation is particularly sensitive to CD40 signaling thresholds.
