Granulocytes

Granulocyte

(Science: haematology) leucocyte with conspicuous cytoplasmic granules. In humans the granulocytes are also classified as polymorphonuclear leucocytes and are subdivided according to the staining properties of the granules into eosinophils, basophils and neutrophils (using a Romanovsky type stain), some invertebrate blood cells are also referred to, not very helpfully, as granulocytes.

Specific memory in Innate Immune System

... mentioned above. The antigen recognition via MHC belongs to adaptive immunity. T-cells cannot recognize antigen directly like macrophage and granulocytes do, so they need a help from some other cells (APCs) to process the antigen into simple peptide and present it with MHC to them. The principle ...
