Attack general invading pathogens. Three types are neutrophils, basophils and eosinophils.
White blood cell with poorly visible cytoplasmic granules
A type of white blood cell that engulfs invading microbes and contributes to the nonspecific defenses of the body against disease.
Agranular leukocyte that is able to migrate into tissues and transform into a macrophage. Produced in Red bone marrow
a type of white blood cell that engulfs dead pathogens that have been killed by antibodies via phagocytosis
Make antibodies to destroy foreign pathogens
form in the bone marrow and release antibodies that fight bacterial infections
Lymphocytes that develop in the thymus and are responsible for cell-mediated immunity. Their cell-surface antigen receptor is called the T-cell receptor.
the cells that perform effector functions during an immune response, such as secreting cytokines (ie helper T cells), killing microbes (ie macrophages, neutrophils, and eosinophils), killing microbe-infected host cells (ie CTL's), or secreting antibodies (ie differentiated B cells); B cell effector cells would be memory cells or plasma cells; T cell effector cells would be T helper cells or cytotoxic T cells
cells that develop from B cells and produce antibodies.
B lymphocytes that do not become plasma cells but remain dormant until reactivated by the same antigen.
An immune response in which the binding of antibodies to the surface of a microbe facilitates phagocytosis of the the microbe by a macrophage
specialized white blood cells that patrol the body searching for antigens that produce infections. APC phagocytes
Are monocytes but name change when enter tissue
destroy bacteria etc. and
report back to 'control centre'
Antibodies block viral binding sites & coats bacteria
a clumping of bacteria when held together by antibodies (agglutinins) Enhances phagocytosis
Souble antigens can be precipitated. Enhances phagocytosis
Leads to cell lysis
