It has become well-accepted that B cells in all vertebrates are functional antibody-secreting cells (ASCs) for the production of particular antibodies in response to particular invading foreign antigens and that they play important roles in adaptive immunity (1). Phagocytosis can be a particular type of endocytosis of phagocytes by which strong particles (which includes microbial pathogens) are internalized to type phagosomes and phagolysosomes, followed by antigen degradation to destroy the invaders or continued processing of antigenic details, sooner or later initiating adaptive immunity in vertebrates (two). Phagocytosis plays an important function of linking the innateFrontiers in Immunology www.frontiersin.orgMay 2020 Volume 11 ArticleWu et al.Phagocytic B Cells in Fishand adaptive immune responses in vertebrates. Classical phagocytosis is mainly accomplished by “professional” phagocytes, including macrophages/monocytes, neutrophils, and dendritic cells, but some “amateur” phagocytes (including epithelial cells and fibroblasts) are in a position to engulf particulate antigens to a substantially lower degree in comparison to professional phagocytes (5). Though B cells are deemed to be among the 3 major skilled antigen-presenting cells (APCs), it’s well-recognized that they have the key duty of binding precise soluble antigenic peptides by way of B-cell receptors (BCRs) but usually do not phagocytose and present substantial non-specific particulate antigens. For that reason, the long-held paradigm i.
