immunology chapter 2

hometopoiesis

occurs in the bone marrow, the process of creating new immune cells

basophil/ mast cells

inflammation, allergies, histamine release (mast cells in skin)

eosinophil

antiviral activity, antiparasite activity

neutrophil

initiate phagocytosis in bacterial cells, most abundant

monocyte

generates macrophages and dendritic cells

myeloid progenitor generates

monocytes, granulocytes (neutrophils, eosinophils, basophils/mast cells) platelets, erythrocytes

lymphoid cells

dendritic cell, T cell, B cell, innate lymphoid cell (ILC)

cluster of differentiation

molecules located on the surface of lymphocytes, can be used to identify different lymphocytes

primary lymphoid organs

where immune cells originate, bone marrow and thymus

secondary lymphoid organs

lymph nodes, spleen, mucosa-associated lymphoid tissue (MALT), GALT
