Texto completoAim: The loss of blood-brain barrier (BBB) integrity is a hallmark of multiple sclerosis. It is associated with a disorganization of junctional molecules and an upregulation of cell adhesion molecules essential for immune cell transmigration. Identifying novel key players involved in this process is thus crucial for the development of MS therapies aimed at promoting BBB integrity and decreasing leukocytes trafficking into the central nervous system (CNS) during neuroinflammation. In this study, the specific role of the adhesion molecule ALCAM, found on BBB endothelial cells (BBB-ECs) and subsets of leukocytes, was assessed. Methods: We first identified ALCAM as an important molecule upregulated during inflammation in a proteomic screen of in vitro cultured primary human BBB-ECs. In order to study the effects of ALCAM on leukocyte transmigration, both active and passive experimental autoimmune encephalomyelitis (EAE) was induced in ALCAM KO and WT animals. The specific role of ALCAM during leukocyte transmigration was also assessed using a modified adhesion assay under sheer-stress, in which leukocytes flow across a capillary-like channel lined with a monolayer of BBB-ECs under physiological pressure. Results: Using the modified adhesion assay, we demonstrated that anti-ALCAM blocking antibodies significantly reduce the rolling and the adhesion of human CD14+ monocytes interacting with primary human BBB-ECs, as well as prevent their overall decrease in velocity. Concurrently, we also observed a significant reduction in the migration of ex vivo CD14+ monocytes, across a monolayer of human BBB-ECs. These monocytes also migrated more rapidly and in higher number across meningeal endothelial cells, as compared to BBB-ECs. While similar observations were made using ex vivo CD4+ T lymphocytes, we failed to reproduce these results using in vitro activated Th1 and Th17 cells. In opposition to our in vitro data, ALCAM KO mice developed a more severe active EAE associated with a significant increase in perivascular infiltration of pro-inflammatory lymphocytes (Th1/Th17) and M1 monocytes/macrophages, as compared to WT controls. In addition, EAE transfer experiments, in which ALCAM KO mice received WT MOG-reactivated splenocytes, suggested that the pathophysiology observed in active EAE was linked to the absence of ALCAM on BBB-ECs. Phenotypic characterization of un-immunized ALCAM KO mice revealed a reduced expression of BBB junctional proteins. Further analysis showed that ALCAM is indirectly associated with tight junction molecules of the BBB-ECs, which explains the increased CNS parenchymal blood vessel in vivo permeability in ALCAM KO animals. Correlating with these data, primary culture of mouse brain BBB-ECs was shown to possess a lower TEER and an increased permeability coefficient. Conclusion: Collectively, our data provide evidence of the implication of ALCAM in monocyte transmigration, but not Th1 or Th17 lymphocyte diapedesis across CNS endothelium. Our results also point to a biologically crucial function of ALCAM in maintaining BBB integrity by acting as an adaptor molecule between tight junctions and the cytoskeleton. As such, the absence of ALCAM at the level of BBB-ECs indirectly promotes the recruitment of pro-inflammatory leukocytes in the CNS of EAE animals by increasing the BBB vessels permeability.

Texto completoObjective: In multiple sclerosis (MS), pro-inflammatory lymphocytes use adhesion molecules to cross the blood-brain barrier (BBB) and accumulate in central nervous system (CNS) lesions. CD4 T lymphocytes polarized into auto-aggressive encephalitogenic TH17 (IL-17 secreting) are known to partake in MS lesion formation. Much less is known about the role of CD8 TC17. Identification of specific surface markers and adhesion molecules expressed by TH17 and TC17 lymphocytes would allow further characterization of these pathogenic subsets and would provide new therapeutic targets in MS. Methodology: We identified MCAM in a proteomic screen of human BBB endothelial cells (ECs) and on a subset of T lymphocytes. We characterized the phenotype and function of MCAM-expressing cells ex vivo, in vitro and in situ using human and mouse material obtained from controls, MS subjects and Experimental Autoimmune Encephalomyelitis (EAE) animals. Results: MCAM is expressed by human BBB-ECs and by human effector memory CD161+ and CCR6+ T lymphocytes. Both CD4 and CD8 MCAM+ lymphocytes express more IL-17, IL-22, GM-CSF and Gz B than MCAMneg lymphocytes. Moreover, MCAM is strikingly up-regulated in human on CD4+ and CD8+ T lymphocytes during MS relapses, while treatment decreases MCAM expression. In situ, MCAM+ CD8 and CD4 T lymphocytes are present in perivascular infiltrates of MS and EAE CNS specimens, while MCAM expression is up-regulated on BBB-ECs within lesions. In vitro, MCAM+ CD8 T lymphocytes display higher killing capacity of oligodendrocytes, and MCAM blockade reduces CD8 TC17 and CD4 TH17 transmigration across human BBB-ECs. In vivo, depletion of MCAM+ cells from reactivated CD4 T lymphocytes and from CD8 T lymphocytes decreases clinical symptoms in adoptive transfer EAE. Furthermore, expression of MCAM is up-regulated on CD4 and CD8 T lymphocytes in the TCR1640 transgenic mice, a model of spontaneous EAE. Finally, blocking MCAM in both MOG35-55-induced and spontaneous primary progressive EAE attenuates chronic neurological deficits. Conclusions: Our data demonstrate that encephalitogenic IL-17-producing lymphocytes with high effector and migratory capacity express MCAM, and that MCAM could serve as a biomarker for MS and a valuable target for the treatment neuroinflammatory conditions.

Texto completoMultiple sclerosis is an idiopathic inflammatory disease of the central nervous system. It is characterized by the formation of focal perivascular lesions and demyelination of the surrounding area, which appear concomitantly to a massive immune cell infiltration and disruption of the blood brain barrier. Experimental autoimmune encephalomyelitis is the animal model most extensively used for the study of multiple sclerosis. Unfortunately, this model does not mimic many aspects of the human disease. The goal of this project is to further the characterization of a new transgenic model of spontaneous experimental autoimmune encephalomyelitis, the TCR1640 model, and to validate it as a relevant tool for the study of multiple sclerosis physiopathology and treatment. The TCR1640 mouse possesses a transgenic T cell receptor which recognizes a myelin peptide and triggers an autoimmune response against endogenous myelin in the central nervous system. In situ and in vitro observations have led to the identification of early changes which appear at the neurovascular unit in presymptomatic TCR1640 animals. This early disruption of blood brain barrier homeostasis is linked to the establishment of a proinflammatory immune profile in the periphery. Animals at the chronic stage show sustained inflammation of the central nervous system parenchyma and massive leukocyte infiltration, compared to animals in acute phase of disease. An in vivo experiment has allowed modulating the disease by treatment with a multiple sclerosis-approved therapy, in wild type mice which had received reactivated CD4+ T cells from TCR1640 animals. Finally, the implication of new cell adhesion molecules in the development and maintenance of spontaneous experimental autoimmune encephalomyelitis has been suggested by in vitro study of melanoma cell adhesion molecule (CD146) and activated leucocyte cell adhesion molecule (CD166). The results obtained in this study suggest that the TCR1640 model is a valuable asset in the study of neuroimmune diseases such as multiple sclerosis. It could also be used to validate new therapeutic strategies for the treatment of this disease.

Texto completoMultiple Sclerosis (MS) is characterized by perivascular infiltrations of immune cells and by demyelination in the central nervous system (CNS). These two hallmarks of the disease are associated with the disruption of the blood-brain barrier (BBB). The recruitment of monocytes, macrophages and dendritic cells, the so-called myeloid antigen-presenting cells (APCs), in the CNS through the BBB is thought to play a crucial role in the initiation and the persistence of the disease. Therefore the identification of the molecular mechanisms involved in the migration of myeloid APCs into the CNS is considered a valid therapeutic option in MS. Nerve injury-induced protein (Ninjurin)-1, a novel adhesion molecule that mediates homophilic binding, was found to be expressed in the vascular endothelium of the BBB following a proteomic screen of human BBB-associated proteins. Ninjurin-1’s expression increases during an inflammatory context in primary cultures of endothelial cells of the BBB (BBB-ECs) and on ex vivo and in vitro generated myeloid APCs. In addition, infiltrating APCs in human MS lesions and in the CNS of the murine model of MS, the mice affected with experimental autoimmune encephalomyelitis (EAE), express high levels of Ninjurin-1. Using an experimental model of the BBB, the neutralization of Ninjurin-1 specifically restricts the migration of monocytes across the BBB-ECs without affecting the recruitment of lymphocytes or the permeability of the BBB-ECs. Finally, EAE mice treated with a Ninjurin-1 blocking peptide have reduced disease severity and a reduced infiltration of myeloid APCs in the CNS, as compared to the control group. Our results show that Ninjurin-1 is an adhesion molecule of the BBB involved in the recruitment of myeloid APCs to the CNS and is also a potential therapeutic target to dampen CNS inflammatory processes, as occurs in MS.
