Class-switch recombination (CSR) and somatic hypermutation (SHM) occur during the
differentiation of germinal center B cells (GCBs). Activation-induced cytidine
deaminase (AID) is responsible for both CSR and SHM in GCBs. Here, we show that
ablation of PTEN through the C?1-Cre mediated recombination significantly
influences the CSR and SHM responses. The GCs fail to produce the IgG1 B cells,
the high affinity antibodies and nearly lost the dark zone (DZ) in
Pten(fl/fl)C?1(Cre/+) mice after immunization, suggesting the impaired GC
structure. Further mechanistic investigations show that LPS- and interleukin-4
stimulation induced the transcription of C?1 in IgM-BCR expressing B cells, which
efficiently disrupts PTEN transcription, results in the hyperphosphorylated AKT
and FoxO1 and in turn the suppression of AID transcription. Additionally, the
reduced transcription of PTEN and AID is also validated by investigating the
IgM-BCR expressing GCBs from Pten(fl/fl)C?1(Cre/+) mice upon immunization. In
conclusion, PTEN regulated AID transcription in GCBs is essential for the CSR and
IgG antibody responses.
