Preclinical Efficacy Models of Parkinson's Disease: 6OHDA & Acute MPTP

Posted by MD Biosciences on Aug 11, 2011 10:03:00 PM

MD Biosciences, a Preclinical Contract Research Organization (CRO), offers in vivo models for the study of Parkinson's Disease (PD). The 6-OHDA and acute MPTP models for PD have been well characterized with the underlying mechanisms of toxicity well understood. Both models are useful tools in evaluating potential neuroprotective therapies providing the ability to target any differences in motor activities and determine whether a drug differentially affects a specific motor behavior.

Parkinson's Disease Background 
Parkinson's Disease (PD) is typically an adult-onset progressive neurodegenerative movement disorder that affects millions of people worldwide. Pathologically, PD is characterized by the profound and specific loss of dopaminergic (DAergic) neurons in the substantia nigra pars compacta (SNpc) of the midbrain. Other areas interconnected with the SNpc, the caudate and putamen, collectively known as the striatum, also show remarkable loss of their projection fibers. In accordance with insult to brain regions involved in controlling coordinated movements, the cardinal symptoms of PD include bradykinesia, resting tremor, rigidity, and postural instability. Due to its complex pathology, however, no disease model has yet to faithfully replicate all aspects of human PD. Converging lines of evidence from toxin-induced and genetic models have continued to further our understanding of the pathological processes underlying PD and lend themselves as useful systems for the examination of therapeutic interventions.

PD Whitepaper & Preclinical Efficacy Studies 
MD Biosciences has released a new whitepaperdiscussing the various efficacy models of PD, the underlying mechanisms of each model and their usefulness as tools for the development of new therapies and interventions. Additionally, MD Biosciences offers these classical models of PD as contracted research studies as part of our portfolio of Neurology Discovery Services. A copy of the whitepaper "What in vivo models have revealed about the pathogenesis and treatment of PD" can be downloaded at http://www.mdbiosciences.com

MD Biosciences to Showcase Preclinical Capabilities at Neuroscience Conf

Posted by Amy Clausen on Nov 11, 2008 11:15:00 AM

St Paul, MN, November 11, 2008 – MD Biosciences, a global biotechnology company focused in inflammations & neurology research will showcase its pre-clinical capabilities at the 2008 Neuroscience Conference in Washington, DC, November 15 – 19th, 2008, booth 1825. Capabilities included in the showcase are efficacy disease models within Multiple Sclerosis (MS), Gliosis, Parkinson’s Disease, Nociceptive, Neuropathic, Post-operative and Inflammatory Pain.

Multiple Sclerosis:

Multiple sclerosis is a demyelinating disease of the CNS. Due to the clinical and pathological similarities of EAE and MS, EAE has been used as a model for the study of human demyelinating disease and is characterized by a relapsing-remitting disease course with subsequent progressive disability.

  • MBP-induced EAE
  • MOG-induced EAE
  • PLP-induced EAE.


Gliosis is a proliferation of astrocytes in the central nervous system (CNS) in response to injury which results in scar formation. Astrocytes react to injury by hypertrophy and up-regulation of the glial-fibrillary acidic protein. Gliosis, along with neuronal loss, is a prominent feature of many diseases of the central nervous system.

Parkinson’s Disease:

Parkinon's Disease (PD) is a neurogenerative disorder characterized by reduction in striatial (DA) content caused by the loss of dopaminergenic neurons in the Substantia Nigra part compacta (SNpc) and their proportions to the striatum.

  • Acute MPTP
  • Chronic MPTP
  • 6-OHDA

MD Biosciences offers Nociceptive, Neuropathic and Inflammatory Pain models:.

  • Tail Flick
  • Visceral Pain
  • Caspaicin
  • Post-operative pain
  • Chronic Constriction Injury (CCI, Bennett & Xie)
  • Taxol induced Neuropathic Pain
  • Spinal Nerve Ligation (Chung)
  • STZ Diabetic Neuropathy
  • Carrageenan Induced Inflammatory Pain
  • Adjuvant (CFA) induced Inflammatory Pain
  • Arthritic and Monoarthritic Pain.
