The B-cell receptor (BCR) is a transmembrane protein on the surface of a B cell. 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).
B cells, unlike the other two classes of lymphocytes, T cells and natural killer cells, express B cell receptors (BCRs) on their cell membrane. [1] BCRs allow the B cell to bind to a foreign antigen, against which it will initiate an antibody response. [1] B cell receptors are extremely specific, with all BCRs on a B cell recognizing the same ...
CD79 (Cluster of Differentiation 79) is a transmembrane protein that forms a complex with the B-cell receptor (BCR) and generates a signal following recognition of antigen by the BCR. CD79 is composed of two distinct chains called CD79A and CD79B (also known as Igα and Igβ); these form a heterodimer on the surface of a B cell stabilized by ...
CD32B is an inhibitory surface receptor that is part of a large population of B cell co-receptors, which act to modulate signaling. [3] Activated CD32B has the ability to cross-link with B cell receptors (BCRs), which increases the threshold for B cell activation and downregulates antibody production in the presence of IgG. [ 5 ]

BLNK is essential for normal B-cell development as part of the B cell receptor signaling pathway. [supplied by OMIM] [10] [23] [24] Evidence also suggests that BLNK may have tumor suppressive activity through its interaction with Bruton's tyrosine kinase (Btk) [25] [26] and regulation of the pre-B cell checkpoint.

The ability to obtain data quickly from tens or hundreds of thousands of cells, one cell at a time, should provide a good idea, of the size of the person's immune repertoire. These large-scale adaptive immune receptor repertoire sequencing (AIRR-seq) data require specialized bioinformatics pipelines to be analyzed effectively. [6]
The most common simplified overview description of the B cell differentiation pathway involves the following steps: an antigen interacts with the corresponding surface membrane immunoglobulin after which the B cell begins expressing receptors for growth factors secreted by T cells (BCGFs and IL-2), after these factors bind, the lymphocytes ...
