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...

Options for treatment of multidrug-resistant (MDR) Acinetobacter baumannii infections are extremely limited. Minocycline intravenous is active against many MDR strains of Acinetobacter, and Clinical and Laboratory Standards Institute breakpoints exist to guide interpretation of minocycline susceptibility results with Acinetobacter. In addition, minocycline intravenous holds a US Food and Drug A...

Minocycline (25 to 100 micrograms/g) dose dependently increased serum glutamic oxalacetic transaminase, urea, and bilirubin levels, and the hepatic triglyceride content in mice. In animals pretreated with phenobarbital to enhance minocycline metabolism, the effects on liver triglycerides were attenuated, while the changes in serum glutamic oxalacetic transaminase, urea, and bilirubin were enhan...

The DOMINO study group has published the report of its ‘futility study’ of minocycline treatment in HD. Minocycline and a placebo pill were tested over 18 months. A futility study is designed to make it relatively easy for a drug to be recommended for larger studies, but minocycline treatment wasn’t promising enough and the study authors found that further trials with minocycline were “not warr...

Neuropathic pain occurs after peripheral nerve damage, inflammation or infection. In this situation, microglial cells become activated and play a key role in producing pain. Minocycline (microglia inhibitor), was reported to reduce pain when used preventively. However, it seems that, when used after nerve injury, results in its pain reducing effects are different. In this regard, to assess the ...

Minocycline is a tetracycline family antibiotic that has anti-inflammatory and immunomodulatory properties. These properties have shown promise in the treatment of conditions such as rheumatoid arthritis, Huntington disease, and multiple sclerosis. As lymphocyte activation is involved in the pathogenesis of many of these diseases, T cells are postulated to be a primary target in minocycline the...

Minocycline prevents oxidative protein modifications and damage in disease models associated with inflammatory glial activation and oxidative stress. While the drug has been assumed to act by preventing the upregulation of proinflammatory enzymes, we probed here its direct chemical interaction with reactive oxygen species. The antibiotic did not react with superoxide or NO radicals, but peroxyn...

Interleukin (IL)-6 has been shown to be a major contributing factor in growth and progression of ovarian cancer. The cytokine exerts pro-tumorigenic activity through activation of several signaling pathways in particular signal transducer and activator of transcription (STAT3) and extracellular signal-regulated kinase (ERK)1/2. Hence, targeting IL-6 is becoming increasingly attractive as a trea...

BACKGROUND The neuroprotective role of minocycline in the treatment of brachial plexus injury is controversial. OBJECTIVE To study the neuroprotective effect of minocycline via different routes in adult Sprague Dawley rats with brachial plexus injury. METHODS The C7 nerve roots of the animals were avulsed via an anterior extravertebral approach. Traction force was used to transect the ventr...
