The study explores how Notch2 signaling manages the structural organization of lymph nodes by directing the development of specialized fibroblastic reticular cells. Researchers identified a unique circuit where homeostatic mature dendritic cells provide continuous Jagged1 signals to maintain a specific population of Ccl19-high fibroblasts in the central T cell zone. This interaction creates distinct chemical gradients that are essential for the proper compartmentalization of immune cells, specifically clustering CD8+ T cells and supporting the formation of memory T cell precursors. The…
