You are studying a particular type of immune cell, but you are not sure which type it is. It is a relatively large, ovoid cell and has an extensive array of rough endoplasmic reticulum. Biochemical studies indicate that your cells lack any surface cluster designation (CD) proteins. What kind of cell might you have?
|B|| TH lymphocyte|
|C||natural killer cell|
a. Plasma cells act as effector cells of the B-cell lineage
b. Unlike B cells, immunoglobulins are not present on the surface of plasma cells
c. A plasma cell produces antibody of a single antigen specificity/ class and allotype and a single light chain type.
d. Thay have abundant endoplasmic reticulum and golgi vesicles.
e. They have a short life span of few days to few weeks unlike memory B cells which can have a life span of 20 yrs.
