WebAntibodies can bind to antigens directly. The antigen must effectively bind with a naive B cell’s membrane-bound antibody in order to set off differentiation, or the process of becoming one of the new forms of a B cell. Memory B cells express the same membrane-bound antibody as the original naive B cell, or the “parent B cell”. WebAntigens are anything that causes an immune response. Antigens can be entire pathogens, like bacteria, viruses, fungi, and parasites, or smaller proteins that pathogens express. Antigens are like a name tag for each pathogen that announce the pathogens’ presence to your immune system. Some pathogens are general, whereas others are very specific. earthe gummi squares
