Lymphatic endothelial S1P promotes mitochondrial function and survival in naive T cells
The chemoattractant S1P is identified as an extrinsic factor that supports naive T cell survival, and acts via a signalling mechanism to maintain mitochondrial content and function.

Dendritic cells control fibroblastic reticular network tension and lymph node expansion
During inflammation, the lymph node stromal compartment is shown to accommodate high numbers of infiltrating lymphocytes by relaxing the cytoskeleton of fibroblastic reticular cells, allowing the latter to stretch and the lymph node to expand.

Podoplanin maintains high endothelial venule integrity by interacting with platelet CLEC-2
A transmembrane O-glycoprotein podoplanin (PDPN) expressed on fibroblastic reticular cells is the activating ligand for platelet receptor CLEC-2; this interaction leads to perivenular release of sphingosine-1-phosphate and expression of VE-cadherin on high endothelial venules, a key process for the maintenance of vascular integrity in lymph nodes.
