WebJan 17, 2024 · However, B cell recognition of antigens is not the only element necessary for B cell activation. B cells that have not been exposed to antigen, also known as naïve B cells, can be activated in a T cell-dependent or independent manner. T cell dependent activation is activation of B cells by type 2 helper T cells in the lymph nodes. WebWhen an effector B cell (plasma cell) becomes activated it produces memory and effector B cells. A memory B cell lasts for a long time so if in the future the pathogen comes back it can proliferate effector and memory cells. A effector B cell on the other hand proliferates antigens immediately to fight off the current infections. photomax studio
