Overview
This article describes a simple immunoassay to measure pro-inflammatory cytokines, particularly IL-1 beta, in patients with autoinflammatory phenotypes. The method involves stimulating whole blood cultures with lipopolysaccharide to evaluate cytokine secretion in supernatants.

What is the significance of measuring pro-inflammatory cytokines?
Measuring pro-inflammatory cytokines helps in diagnosing and understanding inflammatory diseases.
How does the stimulation with LPS work?
LPS activates immune cells to produce cytokines, mimicking a microbial infection.
What are the advantages of using whole blood for this assay?
Whole blood assays are practical and can reflect the in vivo immune response more accurately.
Can this method be used for other cytokines?
Yes, the method can be adapted to measure various pro-inflammatory cytokines.
Is this method suitable for low blood volume samples?
Yes, it is particularly useful when the volume of blood obtainable is limited.
