A New Perspective on B Cell Antibody Responses: Revisiting the Impact of Antigen Form

Key Points

• This review aims to update the understanding of B cell antibody responses by integrating recent research on antigen characteristics and immune outcomes.
• Synthesis of recent studies on B cell responses and antigen forms
• Analysis of the role of antigen physical characteristics in immune signaling
• Discussion of novel vaccine formats, including polyvalent nanoparticles.
• Antigen characteristics significantly influence BCR signaling and APC selection.
• B cells can act as professional APCs alone or with DCs, emphasizing collaboration in T cell activation.
• Antigen forms dictate the anatomical distribution of immune responses, affecting the diversity and magnitude of responses.
