Multi-site ultrasound-guided fine needle aspiration to study cells and soluble factors from human lymph nodes

Abstract:
Lymph nodes (LNs) are specialized secondary lymphoid tissues essential to the priming and maintenance of adaptive immune responses, including the B cell germinal center response; thus, they are central to immunity. However, the anatomically restricted and time-resolved nature of immune priming means that sampling disease-relevant human LNs requires specialized techniques. This article describes the application of ultrasound-guided fine-needle aspiration (FNA) to sample LNs, using cervical LNs of the head and neck as an exemplar. This minimally invasive technique allows collection of both immune cells and cell-free material that are relevant to both neuroimmune diseases and basic lymphatic functions. Downstream use of cellular material can include multiplexed flow cytometry, single-cell transcriptome sequencing (RNA-seq), and B cell cultures. The cell-free supernatant can be used for proteomics or other similar 'omics approaches. This unit describes collection of samples by FNA as well as processing and storage of samples for downstream assays. © 2024 The Author(s). Current Protocols published by Wiley Periodicals LLC.
