PLASMABLAST Meaning and
Definition
-
A plasmablast is a type of activated B-cell in the immune system that plays a crucial role in the humoral immune response. It is characterized as a large, antibody-secreting cell that is derived from B lymphocytes upon encountering an antigen.
Following exposure to an antigen, B-cells undergo a series of differentiation processes, leading to the production of plasmablasts. The plasmablasts are highly proliferative cells that rapidly divide to produce a large number of cells. They are responsible for the immediate secretion of antigen-specific antibodies called immunoglobulins into the bloodstream.
Plasmablasts possess distinct morphological features, such as abundant cytoplasm, a prominent nucleus, and a well-developed endoplasmic reticulum. These cellular structures enable them to efficiently synthesize and secrete large amounts of antibodies.
Plasmablasts are critical in mounting an effective immune response against invading pathogens. By producing and releasing antibodies, they aid in the neutralization and removal of pathogens, preventing them from causing harm to the body. Additionally, plasmablasts contribute to the establishment of immunological memory. Some plasmablasts further differentiate into long-lived plasma cells that reside primarily in the bone marrow, where they continuously produce antibodies to provide long-term protection.
Overall, plasmablasts serve as a vital component of the immune system, enhancing the body's ability to fight off infections and providing immunity against future encounters with similar antigens.

Etymology of PLASMABLAST
The word "plasmablast" is composed of two components: "plasma" and "blast".
The term "plasma" originated from the Ancient Greek word "plásma" (πλάσμα), meaning "shape" or "form". In early medical usage, "plasma" referred to the colorless fluid part of the blood, while in modern biology, it generally refers to the fluid component of the blood that carries various substances such as cells, proteins, and nutrients.
The word "blast" comes from the Old English word "blǣst", which means a gust of wind or a blowing. In the context of biology, "blast" is used to describe an immature or developing cell. It is derived from the Greek word "blastos" (βλαστός), meaning "sprout" or "bud".
