What are macrophages?
Cells produced by the differentiation of monocytes in tissues.Macrophages function in both non-specific defense (innate immunity) as well as help initiate specific defense mechanisms (adaptive immunity) of vertebrate animals.
What is a neutrophil?
Neutrophil granulocytes are the most abundant type of white blood cells in mammals and form an essential part of the innate immune system.
What are T-Cells?
T cells or T lymphocytes belong to a group of white blood cells known as lymphocytes, and play a central role in cell-mediated immunity.
What are B-Cells?
B cells are lymphocytes that play a large role in the humoral immune response (as opposed to the cell-mediated immune response, which is governed by T cells). B cells are an essential component of the adaptive immune system.
