IgH V-Region Sequence Does Not Predict the Survival Fate of Human Germinal Center B Cells¹

Molecular Immunogenetics, Oklahoma Medical Research Foundation, Oklahoma City, OK 73104

Germinal center (GC) B cell survival fate is governed in part by the outcome of successful/failed BCR-mediated interactions with accessory cells. However, the extent to which the BCR primary sequence influences such interactions is not fully understood. Over 1000 IgV_H4 family cDNAs were sequenced from living (annexin V^–) and apoptotic (annexin V⁺ or from within tingible body macrophages) GC B cell fractions from seven tonsils. Results surprisingly demonstrate that living and dying GC B cells do not significantly differ in IgV_H, D, or J_H gene segment use; HCDR3 length or positive charge; or mutation frequency. Additionally, equivalent IgH cDNA sequences were identified in both fractions, suggesting that BCR sequence alone is an unreliable predictor of GC B cell survival.
