WebThe canonical B cell populations thus recognized in the human peripheral blood are discussed in detail below and include: transitional cells, naïve B cells, memory B cells, circulating marginal zone (MZ) B cells, atypical memory B cells, and ASC. WebMay 1, 2005 · Separation of naive and memory B cells according to expression of CD27 indicates that naive peripheral blood B cells divide slowly (0.46% per day), while memory cells proliferate more rapidly (2.66% per day). These data are compatible with the view that B-cell memory may be maintained by clones of proliferating B cells. Subjects:

WebJan 8, 2024 · Background B-cells play a pivotal role in several autoimmune diseases, including patients with immune-mediated neurological disorders (PIMND), such as neuromyelitis optica (NMO), multiple sclerosis (MS), and myasthenia gravis (MG). Targeting B-cells has been an effective approach in ameliorating both central and peripheral … WebJan 19, 2005 · Autoreactive B cells routinely arise during the immune response to foreign antigen. Although it has been demonstrated that the processes of apoptosis, anergy, and receptor editing maintain tolerance in immature B cells, it is clear that autoreactivity can also arise in mature B cells in a germinal center response ( 1 – 4 ).
WebJul 1, 1997 · In this study we analyzed peripheral blood lymphocytes for the presence of CD19 + lymphocytes and assessed the quantitative levels of the CD19 + B cells in relationship to a variety of clinical parameters.
