MOSPD2 is a therapeutic target for the treatment of CNS inflammation.

In multiple sclerosis and experimental autoimmune encephalomyelitis (EAE), myeloid cells comprise a major part of the inflammatory infiltrate in the central nervous system (CNS). We previously described that motile sperm domain-containing protein 2 (MOSPD2) is expressed on human myeloid cells and regulates monocyte migration in vitro. The role of MOSPD2 in EAE pathogenesis was studied by generating MOSPD2 knock-out (KO) mice and monoclonal antibodies directed against MOSPD2.

Treatment with lecinoxoids attenuates focal and segmental glomerulosclerosis development in nephrectomized rats.

Focal segmental glomerulosclerosis (FSGS) is a scarring process associated with chronic low-grade inflammation ascribed to toll-like receptor (TLR) activation and monocyte migration. We developed synthetic, small-molecule lecinoxoids, VB-201 and VB-703, that differentially inhibit TLR-2- and TLR-4-mediated activation and monocyte migration. The efficacy of anti-inflammatory lecinoxoid treatment on FSGS development was explored using a 5/6 nephrectomy rat model.

Newly characterized motile sperm domain-containing protein 2 promotes human breast cancer metastasis.

Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among women worldwide. Breast cancer metastasis results in poor prognosis and increased mortality, but the mechanisms of breast cancer metastasis are yet to be fully resolved. Identifying distinctive proteins that regulate metastasis might be targeted to improve therapy in breast cancer.

Identification of Motile Sperm Domain-Containing Protein 2 as Regulator of Human Monocyte Migration.

Binding of chemokines to their cognate receptors on monocytes instigates a cascade of events that directs these cells to migrate to sites of inflammation and cancerous tissues. Although targeting of selected chemokine receptors on monocytes exhibited preclinical efficacy, attempts to translate these studies to the clinic have failed thus far, possibly due to redundancy of the target receptor. We reveal that motile sperm domain-containing protein 2 (MOSPD2), a protein with a previously unknown function, regulates monocyte migration in vitro.

Treatment with Oxidized Phospholipids Directly Inhibits Nonalcoholic Steatohepatitis and Liver Fibrosis Without Affecting Steatosis.

Background And Aims: Previous studies demonstrated that toll-like receptors 4 and 2 (TLR-4 and TLR-2), which are expressed on liver-resident Kupffer, hepatic stellate cells, and circulating monocytes, play a role in nonalcoholic fatty liver disease. Lecinoxoids are oxidized phospholipids that antagonize TLR-2- and TLR-4-mediated activation of innate immune cells and inhibit monocyte migration. In this study, we tested the effect of two functionally different lecinoxoids on the development of nonalcoholic steatohepatitis and liver fibrosis in a mouse model.
