The lack of T cell infiltrates is a major obstacle to effective immunotherapy in cancer. Conversely, the formation tumor-associated tertiary-lymphoid-like structures (TA-TLLSs), which are local site humoral and cellular immune responses against cancers, associated with good prognosis, they have recently been detected checkpoint blockade (ICB)-responding patients. However, how these lymphoid aggregates develop remains poorly understood. By employing single-cell transcriptomics, endothelial...
Single-cell transcriptomics promises to revolutionize our understanding of the vasculature. Emerging computational methods applied high dimensional single cell data allow integration results between samples and species, illuminate diversity underlying developmental architectural organization populations. Here, we illustrate these in analysis mouse lymph node (LN) lymphatic endothelial cells (LEC) at resolution. Clustering identifies five well-delineated subsets, including two medullary sinus...
Lymphocyte extravasation from the high endothelial venules (HEVs) of lymph nodes is crucial for maintenance immune homeostasis, but its molecular mechanism remains largely unknown. In this article, we report that lymphocyte transmigration across basal lamina HEVs regulated, at least in part, by autotaxin (ATX) and end-product, lysophosphatidic acid (LPA). ATX an HEV-associated ectoenzyme produces LPA lysophosphatidylcholine (LPC), which abundant systemic circulation. agreement with selective...

Macrophages are critical in driving an immunosuppressive tumor microenvironment that counteracts the efficacy of T-cell-targeting therapies. Thus, agents able to reprogram macrophages toward a proinflammatory state hold promise as novel immunotherapies for solid cancers. Inhibition macrophage scavenger receptor Clever-1 has shown benefit inducing CD8
Lymph nodes (LNs) are highly confined environments with a cell-dense three-dimensional meshwork, in which lymphocyte migration is regulated by intracellular contractile proteins. However, the molecular cues directing intranodal cell remain poorly characterized. Here we demonstrate that lysophosphatidic acid (LPA) produced LN fibroblastic reticular cells (FRCs) acts locally to LPA2 induce T-cell motility. In vivo, either specific ablation of LPA-producing ectoenzyme autotaxin FRCs or...
Clever-1 also known as Stabilin-1 and FEEL-1 is a scavenger molecule expressed on subpopulation of anti-inflammatory macrophages lymphatic endothelial cells (LECs). However, its role in regulating dendritic cell (DC) trafficking subsequent effects immunity have remained unexplored. In this study, we demonstrate that DC from the skin into draining lymph nodes compromised absence Clever-1. By adoptive transfer approaches further show poor due to impaired entrance DCs afferent lymphatics....
In nonobese diabetic (NOD) mice, C. rodentium promotes priming of islet-specific T-cells in pancreatic lymph nodes (PaLN), which is a critical step initiation and perpetuation islet-autoimmunity. To investigate mechanisms by T-cell PaLN, we used fluorescent imaging lymphatic vasculature emanating from colon, followed dendritic cell (DC) migration colon using photoconvertible-reporter evaluated the translocation bacteria to with GFP-C. situ hybridization bacterial DNA.

Abstract Tissue engineering requires the delivery and survival of cells to organ sites needing repair. Previously, we showed that an active laminin peptide (AG73: RKR‐LQVQLSIRT)‐conjugated chitosan membrane promoted cell adhesion spreading in vitro . Here, seeded human keratinocytes onto AG73‐chitosan membranes found nearly 80% were attached within 2 h. The carrying inverted placed exposed muscle fascia on backs nude mice. After 3 days, had migrated from established a stratified...
Naive lymphocytes continuously migrate from the blood into lymph nodes (LNs) via high endothelial venules (HEVs). To extravasate HEVs, undergo multiple adhesion steps, including tethering, rolling, firm and transmigration. We previously showed that autotaxin (ATX), an enzyme generates lysophosphatidic acid (LPA), is highly expressed in ATX/LPA axis plays important role lymphocyte transmigration across HEVs. However, detailed mechanism underlying this axis's involvement has remained...
