Study Notes
Overview of Leukocytes
- Leukocytes (white blood cells) are nucleated cells crucial for the immune response.
- Classified into two groups: granulocytes and agranulocytes based on the presence of specific granules.
Granulocytes
- Characterized by cytoplasmic granules that give the appearance of a grainy cytoplasm.
- Have a single multi-lobed nucleus, segmented into distinct lobes.
Types of Granulocytes
- Neutrophils
- Comprise 50-70% of circulating leukocytes.
- Most common type in blood, involved in phagocytosis.
- Characterized by a nucleus with 2-5 lobes connected by fine strands.
- Presence of small, hard-to-see granules in cytoplasm.
- Eosinophils
- Contain granules that stain red with acidic stains.
- Basophils
- Contain large granules that stain blue with basic stains.
Agranulocytes (Mononuclear Leukocytes)
- Differ from granulocytes due to the lack of prominent cytoplasmic granules.
- Include:
- Lymphocytes: Key players in adaptive immunity.
- Monocytes: Differentiate into macrophages and dendritic cells.
Immune System Overview
- Innate Immunity:
- Non-specific response involving cells like neutrophils, eosinophils, basophils, mast cells, and natural killer cells.
- Does not discriminate between different pathogens.
- Adaptive Immunity:
- Involves a specific response to foreign substances (antigens) through B and T lymphocytes.
- Enables the body to recognize and remember pathogens for faster responses upon re-exposure.
Key Concepts
- Specific granules in granulocytes include secondary granules and azurophilic granules (primary granules).
- Immune response involves both innate and adaptive components for effective defense against infections.
