Abstract

Chemokines are primarily low molecular mass proteins that are produced and usually released by a wide variety of cell types. Differential chemokine responses can be excellent early markers of immune dysfunction, allowing clinical intervention prior to expression of full blown undesirable effector responses. Thus, assessment of the nature and intensity of Ag-dependent chemokine production provides a valuable tool for probing human immune regulation.

Here, we provide detailed instructions on approaches we have developed to assess the nature and intensity of recall responses to a wide variety of exogenous and endogenous antigens capable of consistently stimulating chemokine responses by PBMC from adult and pediatric populations. This chapter is divided into two sections. The first is focused on culture techniques for eliciting antigen-driven chemokine responses for a panel of chemokines that are relevant to immune function. The second section details assay systems for their quantitative analysis.
