Minocycline is a broad-spectrum tetracycline antibiotic. A number of preclinical studies have shown that minocycline exhibits neuroprotective effects in various animal models of neurological diseases. However, it remained unknown whether minocycline is effective to prevent neuron loss. To systematically evaluate its effects, minocycline was used to treat Dicer conditional knockout (cKO) mice wh...

Experimental autoimmune neuritis (EAN) is a widely used animal model of the human acute inflammatory demyelinating polyradiculoneuropathy, which is the most common subtype of Guillain-Barré Syndrome. EAN is pathologically characterized by breakdown of the blood-nerve barrier, infiltration of reactive immune cells, local inflammation, demyelination in the peripheral nervous system and mechanical...

The purpose of this study was to determine the efficacy and putative mechanisms of action of tetracycline and minocycline in inhibiting retinal cell apoptosis after glutamate-induced excitotoxicity and trophic factor deprivation in a retinal cell line (E1A-NR.3) and in primary mixed retinal cell cultures. In addition, a differentiated PC-12 cell line was used to determine whether minocycline wa...

BACKGROUND The autophagic vacuolar myopathies (AVM) are a group of inherited myopathies defined by the presence of autophagic vacuoles in pathological muscle specimens. AVM can be categorized into three groups: acid maltase deficiency, myopathies characterized by autophagic vacuoles with unique sarcolemmal features, and rimmed vacuolar myopathies (RVM). While the pathogeneses of these condition...

PURPOSE Microglial cells have been found to play pivotal roles in various neuronal degenerative diseases such as Parkinson's and Alzheimer's diseases. Minocycline, a microglial inhibitor, has recently been shown to be neuroprotective in various models of cerebral ischemia and degenerative diseases of the brain. This study was conducted to evaluate the neuroprotective effect of minocycline and t...

tetracyclines are broad spectrum antibiotics which are inexpensive and widely available and have an appropriate safety profile. in addition to antibiotical effects, tetracyclines can inhibit matrix metaloproteinase and collagenase, and subsequently reduce inflammation, angiogenesis, and neovascularization. they have partial neuro-protective, anti-apoptotic and antioxidant properties. given thes...
