Specific Immunology Flashcards
Mast cells
Granulocytes
Specialized tissue cells similar to basophils in that they trigger local inflammatory reactions and are responsible for many allergic symptoms.
-Produce histamine
Neutrophils
Polymorphonucleocytes (PMNs)
Granulocytes
Essential blood phagocytes; active engulfers and killers of bacteria.
Basophils
Polymorphonucleocytes (PMNs)
Granulocytes
Function in inflammatory events and allergies.
-Produce histamine
Eosinophils
Polymorphonucleocytes (PMNs)
Granulocytes
Active in worm and fungal infections, allergy, and inflammatory reactions.
-Produces cationic peptides and free oxygen radicals
Monocytes
Agranulocytes
Blood phagocytes that rapidly leave the circulation; mature into macrophages and dendritic cells.
Macrophages
(M) Agranulocytes
Largest phagocytes that ingest and kill foreign cells; strategic participants in certain specific immune reactions.
Dendritic cells
(M) Agranulocytes
Relatives to macrophages that reside throughout the tissues and reticuloendothelial system; responsible for processing foreign matter and presenting it to lymphocytes.
Lymphocytes
Agranulocytes
Primary cells involved in specific involved in specific immune reactions to foreign matter.
T cells
(L) Agranulocytes
Perform a number of specific cellular immune responses such as assisting B cells and killing foreign cells (cell-mediated immunity).
B cells
(L) Agranulocytes
Differentiate into plasma cells and form antibodies (humoral/antibody-mediated immunity).
Natural Killer (NK) cells (also called non-B, non-T lymphocyctes)
Related to T cells but displaying no antigen specificity, these cells are active against cancerous and virally infected cells.
