Protocol for the isolation and purification of human follicular dendritic cells for functional assays
Abstract
Summary: In this protocol, we detail how to isolate and purify human follicular dendritic cells (FDCs) from lymphoid tissues. FDCs play a vital role in antibody development by presenting antigens to B cells in germinal centers. The assay involves enzymatic digestion and fluorescence-activated cell sorting and is successfully applied to various lymphoid tissues, including tonsils, lymph nodes, and tertiary lymphoid structures. Our robust technique enables the isolation of FDCs and facilitates downstream functional and descriptive assays.For complete details on the use and execution of this protocol, please refer to Heesters et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
