Multiple neuroprotective mechanisms of minocycline in autoimmune CNS inflammation
Available therapies mainly target the inflammatory component of the disease but fail to prevent neurodegeneration.
Functional and histopathological data of RGCs and optic nerves revealed neuronal and axonal protection when minocycline treatment was started on the day of immunization.
Furthermore, we demonstrate that minocycline-induced neuroprotection is related to a direct antagonism of multiple mechanisms leading to neuronal cell death such as the induction of anti-apoptotic intracellular signalling pathways and a decrease in glutamate excitotoxicity. From these observations, we conclude that minocycline exerts neuroprotective effects independent of its anti-inflammatory properties.
It doesn't look like they needed Copaxone to achieve these results.
