the team determined that the drug blocks the action of poly(ADP-ribose) polymerase-1 (PARP-1), a protein that can trigger inflammation and cell death.
Glutamate excitotoxicity and complement attack have both been implicated separately in the generation of tissue damage in multiple sclerosis and in its animal model, experimental autoimmune encephalomyelitis.
Treatment with the antioxidant Trolox and inhibition of poly(ADP-ribose) polymerase-1, but not of caspases, protected oligodendrocytes against damage induced by complement. These findings indicate that glutamate sensitization of oligodendrocytes to complement attack may contribute to white matter damage in acute and chronic neurological disorders.
The NO donor significantly increased neuronal death and minocycline was protective under these conditions. Furthermore NO-induced reductions in axonal length were significantly attenuated by minocycline……
in addition to anti-inflammatory properties, minocycline has direct protective effects on neurons and provides further evidence for its use in disorders of the CNS.
