Project description:Background : The G protein-coupled receptor (GPCR) calcitonin receptor-like receptor (CLR) is implicated in cardiovascular and skin diseases, migraine and cancer. Beyond its agonists, receptor activity-modifying proteins and receptor component protein, interacting partners of this GPCR (‘CLR interactome’) are currently unknown. Herein, we defined CLR interactome in primary human dermal lymphatic endothelial cells (HDLEC). Immunoprecipitation (IP) of core- and terminally-glycosylated CLR and label-free quantitative mass spectrometry allowed the identification of 46 novel interaction partners from a total HDLEC proteome consisting of 4,902 proteins. Aims: The main aim of this study was to characterise the interactome of endogenous CLR along with the expression of this GPCR in the context of the proteomic profile of primary human dermal lymphatic endothelial cells cultured in vitro. Methods We used label-free quantitative proteomic analysis to analyse the CLR co-IP eluates and total protein lysates obtained from cultured in vitro primary human dermal lymphatic endothelial cells (from Promocell).

Project description:Analysis of ex vivo isolated lymphatic endothelial cells from the dermis of patients to define type 2 diabetes-induced changes. Results preveal aberrant dermal lymphangiogenesis and provide insight into its role in the pathogenesis of persistent skin inflammation in type 2 diabetes. The ex vivo dLEC transcriptome reveals a dramatic influence of the T2D environment on multiple molecular and cellular processes, mirroring the phenotypic changes seen in T2D affected skin. The positively and negatively correlated dLEC transcripts directly cohere to prolonged inflammatory periods and reduced infectious resistance of patients´ skin. Further, lymphatic vessels might be involved in tissue remodeling processes during T2D induced skin alterations associated with impaired wound healing and altered dermal architecture. Hence, dermal lymphatic vessels might be directly associated with T2D disease promotion. Global gene expression profile of normal dermal lymphatic endothelial cells (ndLECs) compared to dermal lymphatic endothelial cells derived from type 2 diabetic patients (dLECs).Quadruplicate biological samples were analyzed from human lymphatic endothelial cells (4 x diabetic; 4 x non-diabetic). subsets: 1 disease state set (dLECs), 1 control set (ndLECs)

Project description:Vascular endothelial growth factor receptor-2 (VEGFR2) is a key target for regulating the endothelial cell lineage and angiogenesis. It is also expressed by lymphatic endothelial cells (LECs) while its participation in lymphangiogenesis remains inadequately characterized. We demonstrate in this study that VEGFR2 is highly expressed in dermal initial lymphatic vessels and valves. The induced deletion of pan-endothelial Vegfr2 at the neonatal stage produced a potent suppression of dermal lymphatic growth, characterized by a thinner lymphatic diameter, a decreased number of LECs and lymphatic valves. Mechanistically, VEGFR2 insufficiency led to a dramatic decrease in lymphatic VEGFR3, a key regulator mediating signals for lymphatic growth and remodeling. RNA sequencing analysis revealed that GO terms enriched for downregulated genes included biological processes related to EC development while pathways related to hematopoiesis and immune responses were upregulated in the skin of Vegfr2 mutants compared with littermate controls. This was further confirmed by RNA-seq analysis of dermal tissues 48 hours after endothelial Vegfr2 deletion. Consistently, targeting Vegfr2 in PROX1+ cells produced an inhibitory effect on dermal lymphatic growth and recapitulated a similar altered transcriptomic signature. The alteration of lymphatic gene expression was further validated by siRNA-mediated Vegfr2 knockdown in primary LECs, showing a transcriptional trend toward a hematopoietic fate. Findings from this study imply that VEGFR2 is required for the maintenance of endothelial identity, and its insufficiency triggers a transcriptional reprogramming that diminishes VEGFR3-mediated lymphangiogenesis.

Project description:The exit of antigen-presenting cells (APC) and lymphocytes from inflamed skin to afferent lymph is vital for the initiation and maintenance of dermal immune responses. How such exit is achieved and how cells transmigrate the distinct endothelium of lymphatic vessels is however unknown. Here we show that inflammatory cytokines trigger activation of dermal lymphatic endothelial cells (LEC) leading to expression of the key leukocyte adhesion receptors ICAM-1, VCAM-1 and E-selectin, as well as a discrete panel of chemokines and other potential regulators of leukocyte transmigration. Furthermore, we show that both ICAM-1 and VCAM-1 are induced in the dermal lymphatic vessels of mice exposed to skin contact hypersensitivity where they mediate lymph node trafficking of DC via afferent lymphatics. Lastly, we show that TNF_-stimulates both DC adhesion and transmigration of dermal LEC monolayers in vitro and that the process is efficiently inhibited by ICAM-1 and VCAM-1 adhesion-blocking mAbs. These results reveal a CAM-mediated mechanism for recruiting leukocytes to the lymph nodes in inflammation and highlight the process of lymphatic transmigration as a potential new target for anti-inflammatory therapy. Experiment Overall Design: Global gene expression profile of normal dermal lymphatic endothelial cells cultured in media alone (no TNF) compared to that of normal dermal lymphatic endothelial cells stimulated with TNFalpha, 1 ng/ml for 48h.Triplicate biological samples were analyzed from human lymphatic endothelial cells (3 x controls; 3 x TNF treated) and a single sample analyzed from mouse lymphatic endothelial cells (1 x controls; 1 x TNF treated).
