Study Notes
Granulocytes
- Granulocytes are a type of white blood cell characterized by prominent granules in their cytoplasm.
- These granules are released via exocytosis when granulocytes are activated, playing a crucial role in the immune response.
Types of Granulocytes
- Basophils: Involved in inflammatory responses and release histamine.
- Eosinophils: Primarily respond to parasitic infections and allergens.
- Neutrophils: Most abundant granulocytes, responsible for phagocytosing pathogens and playing a key role in the early stages of the immune response.
Agranulocytes
- Agranulocytes lack visible granules in their cytoplasm, differentiating them from granulocytes.
Types of Agranulocytes
- Monocytes: Large cells that differentiate into macrophages and dendritic cells, crucial for phagocytosis and antigen presentation.
- Dendritic Cells: Act as antigen-presenting cells (APCs), important for initiating immune responses.
- Lymphocytes: Include T cells and B cells, vital for adaptive immunity, involved in targeted immune responses.
