Innate immunity supports the initiation of germinal centre reactions

The initiation of germinal centre reactions relies on B cells, having seen the native pathogen, and on interaction of B and T cells at the follicular border. However, in cooperation with the groups of Marie Kosco-Vilbois (Geneva, Switzerland) and Kai Toellner (Birmingham, UK), we have shown that factors associated with innate immunity are also critical for germinal centre formation. Toll-like-receptor 4 was required for the proper formation of the follicular dendritic cell network in B cell follicles and, thus, instrumental for B cell mutation and maturation. This finding contributes to medical research on poor immune responses, e.g. after vaccination of the elderly population.
