CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]

Plasma is the fourth part, and it allows the solid components to move through the arteries and veins throughout your body. Essentially, plasma is the liquid part of the blood. It makes up about 55 ...
Instead, plasma cells are identified through flow cytometry by their additional expression of CD138, CD78, and the Interleukin-6 receptor. In humans, CD27 is a good marker for plasma cells; naïve B cells are CD27−, memory B-cells are CD27+ and plasma cells are CD27++. [5] The surface antigen CD138 (syndecan-1) is expressed at high levels. [6]
All values in Hematology – red blood cells (except hemoglobin in plasma) All values in Hematology – white blood cells; Platelet count (Plt) A few values are for inside red blood cells only: Vitamin B 9 (folic acid/folate) in red blood cells; Mean corpuscular hemoglobin concentration (MCHC)
The mouse CD79A gene, then called mb-1, was cloned in the late 1980s, [8] followed by the discovery of human CD79A in the early 1990s. [9] [10] It is a short gene, 4.3 kb in length, with 5 exons encoding for 2 splice variants resulting in 2 isoforms.
B cells interact with T cells and begin dividing before selection into the plasma cell, partly on the basis of their affinity for antigen. [339] Since SARS-CoV-2 has been in the human population only since December 2019, it remains unknown if the immunity is long-lasting in people who recover from the disease. [340]
