Recent evidence indicates that segmented filamentous bacteria (SFB), "Candidatus Arthromitus", play a unique role in different aspects of the maturation of the immune system, including T cell responses. Thus, it seems particularly relevant in this moment to shortly review the information on these bacteria and their relationship with the immune system, and to actively investigate their morphological aspects. We distinguished a developmental form from a vegetative form of these organisms. These different forms have distinct roles in the life cycle: the developmental form permits a rapid growth of the organisms while the vegetative form permits the attachment of SFB to the follicular epithelium. We have also given special attention to the modes of contact between SFB and the epithelial cells of the terminal ileum to better understand the unique relationship between these bacteria and the immune system.

Abstract

Recent evidence indicates that segmented filamentous bacteria (SFB), "Candidatus Arthromitus", play a unique role in different aspects of the maturation of the immune system, including T cell responses. Thus, it seems particularly relevant in this moment to shortly review the information on these bacteria and their relationship with the immune system, and to actively investigate their morphological aspects. We distinguished a developmental form from a vegetative form of these organisms. These different forms have distinct roles in the life cycle: the developmental form permits a rapid growth of the organisms while the vegetative form permits the attachment of SFB to the follicular epithelium. We have also given special attention to the modes of contact between SFB and the epithelial cells of the terminal ileum to better understand the unique relationship between these bacteria and the immune system.
