Types of Immune Cells Part 2: Myeloid and Lymphoid Lineages
Guided Notes
3 key concepts
- 1
Most immune cells come from hematopoietic stem cells in the bone marrow, which differentiate into either the myeloid or lymphoid lineage.
- 2
Macrophages are phagocytic cells that ingest pathogens and cellular debris, while granulocytes like neutrophils, eosinophils, and basophils release antimicrobial chemicals.
- 3
Adaptive immune cells, including B cells and T cells, derive from the lymphoid lineage and provide specific immunity through antibodies and targeted cell killing.
