Question

Russell bodies are found in
(a) Eosinophils
(b) Monocytes
(c) Mast cells
(d) Plasma

Answer 1

Russell bodies are large eosinophilic, homogeneous, immunoglobulin containing inclusions. They undergo a synthesis of immunoglobulin. They are found in the area that is a clear coloured blood portion along with various salts and minerals.

Complete step by step answer:
Russell bodies are found in plasma. Russell bodies are aggregated and unreleased immunoglobulin components. They are present in the plasma cells but it can exist as smaller particles in the outer extracellular locations. Russell bodies show their presence in the presence of lymphoplasmacellular inflammatory process. Mott selves are Russell bodies that are found in the area of a reactive inflammatory lesion having multiple intracytoplasmic eosinophilic globules.

Additional information:
Eosinophils: Eosinophils are kind of white blood cells that are associated with certain types of allergic reactions. They can be stained by acidic dyes such as eosin. White blood cells constitute eosinophils, basophils, and neutrophils which are together known as granulocytes. They are produced in the bone marrow and released by circulation. After being released by the circulation they migrate into the tissues through lymphatic channels. They are motile and phagocytic. They participate in inflammatory reactions and hypersensitivity with their destructive effects.
Monocytes: Monocytes are the largest types of blood cells which constitute about 7% of leukocytes. The nucleus of monocytes is relatively big and is folded instead of multilobed. These two cells are migratory and can divide. When the cells are appropriately stimulated they can transform into phagocytic macrophages. Monocytes are important for the immune system as they destroy invaders. They facilitate healing and repair. Monocytes are formed in the bone marrow and are released in the peripheral blood where they can circulate for several days.
Mast cells: Mast cells are the tissues of vertebrate animals of the immune system. They intervene in inflammatory responses such as hypersensitivity and allergic reactions. Mast cells release the contents of their granules upon stimulation by an allergen into the surroundings. This process is known as bi granulation. Mast cells are involved in the immune phenomena including autoimmune disease and innate and adaptive immune responses.
So, the correct answer is 'plasma'.

Note: The name mast cells are named after the German word for 'overfed'. Monocytes transform the cells into macrophages that digest foreign substances, diseased cells, and dendritic cells that activate the white blood cells. Eosinophils release some enzymes which attack the cell membranes of the bacteria but they are more active against the parasites. Monocytes move out of the body when there is an infection in the tissue and in about eight hours they enlarge and become macrophages.
