Webb5 mars 2024 · Key Concepts and Summary. B lymphocytes or B cells produce antibodies involved in humoral immunity. B cells are produced in the bone marrow, where the initial stages of maturation occur, and travel to the spleen for final steps of maturation into naïve mature B cells. B-cell receptors (BCRs) are membrane-bound monomeric forms of IgD … WebbAntibody opsonization is a process by which a pathogen is marked for phagocytosis. [1] [2] 1) Antibodies (A) and pathogens (B) free roam in the blood. 2) The antibodies bind to pathogens, and can do so in different formations such as: opsonization (2a), neutralisation (2b), and agglutination (2c).
