The aim of this Keystone symposium will be to: (1) Present the most recent advances in the basic biology of the T cell-dependent B cell response, focusing on Tfh development and function and B cell activation and differentiation (2) address the gap in our understanding the differentiation of B cells into post-activation (memory and plasma cell) fates (3) discuss how furthering our understanding of B cell-T cell interactions can inform vaccine development and (4) present recent findings regarding the role of T-cell dependent B cell response in allergy and autoimmunity. Telcel Buenavista: Peor experiencia en mi vida, el dia 13 de junio 2021 compre un celular Alcatel por emergencia, al dia siguento tuve que recargar otros 100 el dia 15 el celular empezo a fallar diciendo que la bateria estaba sobrecargada, acudi a Telcel, quise cambiarlo y Omar Ramirez DiazGerente General, pidio que dejara el cell por una semana yo tenia que regresar a mi pais. Each B cell produces antibodies which are unique to it. When an antibody binds to an antigen, it flags the pathogen to the immune system for destruction. The antibodies produced by the B cells selectively bind with the antigens and prevent them entering into the host cells. Most importantly, from the vaccine standpoint, it is likely that better understanding of how T cell help shapes the B cell repertoire will allow us to better control the specificity of vaccine-induced immune responses. Antigens can be bacteria, viruses, toxin, etc. CD40 ligand is found on these T helper cells and. While recent years have seen a burst in our understanding of how B cell-T cell interactions drive antibody affinity maturation, a number of gaps remain, including how these interactions influence the differentiation of B cells into effector fates and how they limit the emergence of autoreactive B cell clones. In this situation activated B cells move to the border of the T cell zone to interact with T cells (Figure 2). While this greatly enhances our ability to fight pathogens, it also can lead to the development of allergies and autoimmune disease. B cell-T cell interactions bring about the maturation and production of high affinity antibodies and are key to the establishment of effective humoral immunity.
