Textbook germinal centers?
Models for the development and function of germinal centers (GCs) have been so widely discussed in the original literature that they now appear in immunology textbooks. Unfortunately, many of the tenets of these models have not yet been subjected to adequate experimental scrutiny. Indeed, recent studies have called several of their principal assumptions into question. In addition, the term germ...
متن کاملGerminal Centers without T Cells
Germinal centers are critical for affinity maturation of antibody (Ab) responses. This process allows the production of high-efficiency neutralizing Ab that protects against virus infection and bacterial exotoxins. In germinal centers, responding B cells selectively mutate the genes that encode their receptors for antigen. This process can change Ab affinity and specificity. The mutated cells t...
متن کاملGerminal center B cell maintenance and differentiation are controlled by distinct NF-κB transcription factor subunits
Germinal centers (GCs) are the sites where memory B cells and plasma cells producing high-affinity antibodies are generated during T cell-dependent immune responses. The molecular control of GC B cell maintenance and differentiation remains incompletely understood. Activation of the NF-κB signaling pathway has been implicated; however, the distinct roles of the individual NF-κB transcription fa...
متن کاملTranscription factors of the alternative NF-κB pathway are required for germinal center B-cell development.
The NF-κB signaling cascade relays external signals essential for B-cell growth and survival. This cascade is frequently hijacked by cancers that arise from the malignant transformation of germinal center (GC) B cells, underscoring the importance of deciphering the function of NF-κB in these cells. The NF-κB signaling cascade is comprised of two branches, the canonical and alternative NF-κB pat...
متن کاملDoes Recycling in Germinal Centers Exist?
A general criterion is formulated in order to decide if recycling of B-cells exists in GC reactions. The criterion is independent of the selection and affinity maturation process and based solely on total centroblast population arguments. An experimental test is proposed to verify whether the criterion is fulfilled.
