Plasma Cell - English Definition & Meaning

Definition

A plasma cell is a specialized type of immune cell, a differentiated B lymphocyte, that churns out antibodies. Think of them as tiny antibody factories 💪. They're like the specialized workers on an assembly line, each one designed to produce a specific kind of antibody to fight off invaders. Plasma cells are crucial in fighting infections. They circulate in the blood and reside in tissues. Their main job is to neutralize threats. It's like having a personal army constantly producing weapons against enemies ⚔️.

Etymology

The term 'plasma' comes from the Greek word 'plasma,' meaning 'something molded or formed.' This refers to the fluid-like substance in which these cells are found. 'Cell' is from the Latin 'cella,' meaning 'small room' or 'compartment'. The name reflects the cell's role as a container for the machinery of antibody production. Combined, 'plasma cell' denotes a cell found in the 'molded' or fluid part of blood that is dedicated to a specific function. The term was developed in the late 19th century as scientists began understanding the composition and function of blood.
