Agranulocytes (lymphocytes)

They work by producing antibodies that destroys pathogens

They lack granules in cytoplasm

They have bean-shaped nucleus

Formed in thymus and lymph gland

An example is monocytes.

Types of antibodies produced by lymphocytes

  1. Antitoxins – they neutralize toxins produced by pathogens
  2. Agglutinins – they cause microorganisms to clump together preventing them from multiplying.
  3. Lysins – they digest the walls or cell membrane of microorganisms.
  4. Opsonins – they adhere to the outer surface of microorganisms making it easier for phagocytes to engulf them.
