Macrophage Bactericidal Assays

Methods in Molecular Biology
Mourad Aribi

Abstract

The search for the bactericidal activity of macrophage (Mϕ) is crucial not only during infection, but also to explore its functional activities in normal and pathological conditions, such as autoimmune and inflammatory disorders, allergic inflammation, and cancer. There are several methods exploring the phagocytic and bactericidal activities of Mϕ. This chapter focuses specifically on the technique called antibiotic protection assay and on the methods for the determination of Mϕ production of nitric oxide and hydrogen peroxide as antimicrobial agents and biomarkers of respiratory burst. The protocols presented herein are valid for both Mϕ cell lines and monocyte-derived Mϕs (MDMs).

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
