Raft-like lipid microdomains drive autophagy initiation via AMBRA1-ERLIN1 molecular association within MAMs

Manganelli, Valeria ; Matarrese, Paola ; Antonioli, Manuela ; Gambardella, Lucrezia ; Vescovo, Tiziana ; Gretzmeier, Christine ; Longo, Agostina ; Capozzi, Antonella ; Recalchi, Serena ; Riitano, Gloria ; Misasi, Roberta ; Dengjel, Jörn ; Malorni, Walter ; Fimia, Gian Maria ; Sorice, Maurizio ; Garofalo, Tina

Mitochondria-associated membranes (MAMs) are essential communication subdomains of the endoplasmic reticulum (ER) that interact with mitochondria. We previously demonstrated that, upon macroautophagy/autophagy induction, AMBRA1 is recruited to the BECN1 complex and relocalizes to MAMs, where it regulates autophagy by interacting with raft-like components. ERLIN1 is an endoplasmic reticulum...

Differential expression of CD31 and von Willebrand factor on endothelial cells in different regions of the human brain: potential implications for cerebral malaria pathogenesis

Mbagwu, Smart Ikechukwu ; Filgueira, Luis

In: Brain Sciences, 2020, vol. 10, no. 1, p. 31

Cerebral microvascular endothelial cells (CMVECs) line the vascular system of the brain and are the chief cells in the formation and function of the blood brain barrier (BBB). These cells are heterogeneous along the cerebral vasculature and any dysfunctional state in these cells can result in a local loss of function of the BBB in any region of the brain. There is currently no report on the...

Hypoxia enhances endothelial intercellular adhesion molecule 1 protein level through upregulation of arginase type II and mitochondrial oxidative stress

Liang, Xiujie ; Arullampalam, Prakash ; Yang, Zhihong ; Ming, Xiu-Fen

In: Frontiers in Physiology, 2019, vol. 10, p. -

Hypoxia plays a crucial role in the pathogenesis of cardiovascular diseases. Mitochondrial enzyme arginase type II (Arg-II) is reported to lead to endothelial dysfunction and enhance the expression of endothelial inflammatory adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). In this study, we investigate the role of Arg-II in...

PECAM-1 stabilizes blood-brain barrier integrity and favors paracellular T-Cell diapedesis across the blood-brain barrier during neuroinflammation

Breakdown of the blood-brain barrier (BBB) and increased immune cell trafficking into the central nervous system (CNS) are hallmarks of the pathogenesis of multiple sclerosis (MS). Platelet endothelial cell adhesion molecule-1 (PECAM-1; CD31) is expressed on cells of the vascular compartment and regulates vascular integrity and immune cell trafficking. Involvement of PECAM-1 in MS pathogenesis...

Evaluation of extracellular vesicle function during malaria infection

Malaria is a life-threatening disease caused by Plasmodium parasites, with P. falciparum being the most prevalent on the African continent and responsible for most malaria-related deaths globally. Several factors including parasite sequestration in tissues, vascular dysfunction, and inflammatory responses influence the evolution of the disease in malaria-infected people. P. falciparum-infected...

Characterization and in vivo validation of a three-dimensional multi-cellular culture model to study heterotypic interactions in colorectal cancer cell growth, invasion and metastasis

Cattin, Sarah ; Ramont, Laurent ; Rüegg, Curzio

Colorectal cancer (CRC) is the third cause of cancer-related mortality in industrialized countries. Local invasion and metastasis formation are events associated with poor prognosis for which today there are no effective therapeutic options. Invasion and metastasis are strongly modulated by cells of the tumor microenvironment (TME), in particular fibroblasts and endothelial cells. Unraveling...
