Spatial transcriptomics from clinically non inflammed human lymph nodes
Because of their central role in inflammatory processes pathological alterations in lymph nodes can affect innate and adaptive immunity. However, interpretation of lymph node pathology in humans is hampered by the lack of a reference under homeostatic conditions and a limited understanding of the molecular processes that occur during inflammatory activation. Using a combination of confocal microscopy, flow cytometry, and single cell and spatial transcriptome analysis, our study provides an in-depth characterization of the immunoanatomy of clinically inflammed and non-inflamed human lymph nodes.
