Dormant B cell arising from B cell differentiation. [1] Their function is to circulate through the body and initiate a stronger, more rapid antibody response (known as the anamnestic secondary antibody response) if they detect the antigen that had activated their parent B cell (memory B cells and their parent B cells share the same BCR, thus ...
Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. [1] Their function is to memorize the characteristics of the antigen that activated their parent B cell during initial infection such that if the memory B cell later encounters the same antigen, it triggers an accelerated and robust secondary immune response.
B cell: Plasma B cells; Effector B cells; Plasmocytus; 8-10 Active B cells that produces large amounts of antibodies [4] [15] Memory B cell: Lymphocyte: B cell: MBC; 8-10 Memorizes the characteristics of the antigens; Triggers an accelerated and robust secondary immune response [4] [16] Killer T cell: Lymphocyte: T cell: T lymphocyte ...
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
Germinal center B cells may differentiate into memory B cells or plasma cells. Most of these B cells will become plasmablasts (or "immature plasma cells"), and eventually plasma cells, and begin producing large volumes of antibodies. Some B cells will undergo a process known as affinity maturation. [9]
A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
A B-cell receptor includes both CD79 and the immunoglobulin. The plasma membrane of a B cell is indicated by the green phospholipids. The B- cell receptor extends both outside the cell (above the plasma membrane) and inside the cell (below the membrane). The B-cell receptor (BCR) is a transmembrane protein on the surface of a B cell.
Regulatory B cells (Bregs or B reg cells) represent a small population of B cells that participates in immunomodulation and in the suppression of immune responses. The population of Bregs can be further separated into different human or murine subsets such as B10 cells, marginal zone B cells, Br1 cells, GrB + B cells, CD9 + B cells, and even some plasmablasts or plasma cells.
