Established therapies target primarily the inflammatory component of the disease, but fail to prevent neurodegeneration. Fingolimod (codenamed FTY720) is an oral sphingosine 1-phosphate (S1P) receptor modulator with promising results in phase II trials in multiple sclerosis patients and is under further development as a novel treatment for multiple sclerosis. To evaluate whether FTY720 has neuroprotective properties, we tested this drug in a rat model of myelin oligodendrocyte glycoprotein-induced optic neuritis. FTY720 exerted significant anti-inflammatory effects during optic neuritis and reduced inflammation, demyelination, and axonal damage; however, FTY720 treatment did not prevent apoptosis of retinal ganglion cells (RGCs), the neurons that form the axons of the optic nerve. Consistent with this lack of effect on RGC survival, FTY720 treatment did not improve visual function, nor did it prevent apoptosis of RGCs in vitro. We observed a persistent activation of apoptotic signaling pathways in RGCs under FTY720 treatment, a possible underlying mechanism for the lack of neuroprotection in the presence of strong anti-inflammatory effects, Furthermore, FTY720 shifted the remaining inflammation in the optic nerve toward neurotoxicity by modest up-regulation of potential neurotoxic cytokines. We conclude that FTY720-induced anti-inflammation and axon protection did not of itself protect neurons from apoptotic cell death.

To investigate the influence of methylprednisolone therapy on the survival of retinal ganglion cells (RGCs), the neurons that form the axons of the ON, we used a rat model of myelin oligodendrocyte glycoprotein (MOG)-induced EAE.

Methods: Patients with optic neuritis who attended the University Hospitals of Homburg/Saar, Gottingen, or Hamburg (Germany) were included in this double-blind, placebo-controlled, phase 2 study (ClinicalTrials.gov, NCT00355095). They were randomly assigned to groups receiving either 33,000IU recombinant human erythropoietin intravenously daily for 3 days or placebo as an add-on therapy to methylprednisolone. The primary outcome parameter was change in retinal nerve fiber layer (RNFL) thickness after 16 weeks. Secondary outcome parameters included optic nerve atrophy as assessed by magnetic resonance imaging, and changes in visual acuity, visual field, and visual evoked potentials (VEPs). Results: Forty patients were assigned to the treatment groups (21/19 erythropoietin/placebo). Safety monitoring revealed no relevant issues. Thirty-seven patients (20/17 erythropoietin/placebo) were analyzed for the primary endpoint according to the intention-to-treat protocol. RNFL thinning was less apparent after erythropoietin treatment. Thickness of the RNFL decreased by a median of 7.5 mu m by week 16 (mean +/- standard deviation, 10.55 +/- 17.54 mu m) compared to a median of 16.0 mu m (22.65 +/- 29.18 mu m) in the placebo group (p = 0.0357). Decrease in retrobulbar diameter of the optic nerve was smaller in the erythropoietin group (p = 0.0112). VEP latencies at week 16 were shorter in erythropoietin-treated patients than in the placebo group (p = 0.0011).

Methods: Calcium ion (Ca2 ) influx into the optic nerve (ON) through VDCCs was investigated in a rat model of optic neuritis using manganese-enhanced magnetic resonance imaging and in vivo calcium imaging. After having identified the most relevant channel subtype (N-type VDCCs), we correlated immunohistochemistry of channel expression with ON histopathology. In the confirmatory part of this work, we performed a treatment study using -conotoxin GVIA, an N-type specific blocker. Results: We observed that pathological Ca2 influx into ONs during optic neuritis is mediated via N-type VDCCs. By analyzing the expression of VDCCs in the inflamed ONs, we detected an upregulation of 1B, the pore-forming subunit of N-type VDCCs, in demyelinated axons. However, high expression levels were also found on macrophages/activated microglia, and lower levels were detected on astrocytes. The relevance of N-type VDCCs for inflammation-induced axonal degeneration and the severity of optic neuritis was corroborated by treatment with -conotoxin GVIA. This blocker led to decreased axon and myelin degeneration in the ONs together with a reduced number of macrophages/activated microglia. These protective effects were confirmed by analyzing the spinal cords of the same animals.
