Long-lived bone marrow plasma cells
WebIndeed, experiments in mice revealed that long-lived plasma cells in the bone marrow continue to generate antigen-specific antibody for nearly a year postimmunization, even well after depletion of memory B cells. Evidently, the bone marrow provides unique microenvironments for plasma cell survival and function. Web22 de nov. de 2024 · 58. Lemke A, Kraft M, Roth K, Riedel R, Lammerding D, Hauser AE.
