Witryna4 paź 2024 · Definition. B cells or B lymphocytes are part of the adaptive immune response. Once activated, these white blood cells produce antibodies. B lymphocytes have further roles as antigen-presenting cells and cytokine secretors. This cell type is classified into four main groups: transitional, naïve, plasma, and memory B cells. WitrynaB cells are at the centre of the adaptive humoral immune system and are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens (typically known as antibodies). The function of B cells was discovered in the 1960s by Max Cooper who demonstrated that antibody production …
