eBook: Pain & Inflammation Link | Targets in the Overlap

Posted by MD Biosciences on Jul 13, 2011 9:59:00 PM

MD Biosciences, a preclinical CRO focused in pain and inflammations, has released a new eBook discussing the interactions between the nervous and immune systems and the drug targets that may lie in the overlap. This newly published eBook is meant to be a review of the immune system and inflammation as it relates to pain, specifically neuropathic pain and covers the following: 

  •     Immune system and Inflammation
  •     Pain processing and Neuropathic Pain
  •     Cell types involved in neuro-inflammation aspect of neuropathic pain
  •     Potential inflammation-related drug targets for neuropathic pain
  •     Relevant preclinical models for neuropathic pain

 

Neuropathic pain presents a wide variety of challenges to researchers, not the least of which is the simple fact that neuropathic pain, by definition, requires neuronal damage, which in turn automatically initiates an immune response that often inflicts further damage.

The interactions between the immune and nervous systems in the case of neuropathic pain make for a very complex story that is only beginning to unfold. Fortunately, a variety of good preclinical neuropathic pain models for the simulation of neuropathic pain in humans have been used for some time and enable researchers to advance our understanding of disease mechanisms in the preclinical setting. Currently, existing pharmacological treatments for neuropathic pain, which address predominately neuronal targets, include opioid analgesics, tricyclic antidepressants and cation channel blockers among others. However these drugs treat symptoms and thus only provide temporary relief and are fraught with undesirable side effects such as tolerance and dependence. As the field of neuroimmunology progresses, it is possible that inflammation-associated drug targets may open to new and more effective treatments for neuropathic pain.

High ArthritoMabTM Antibody Cocktail Activity | 18-day RA Model Balb/c Mice

Posted by MD Biosciences on Feb 3, 2011 10:05:00 PM

MD Biosciences, a global biotechnology company focused in inflammations research, has optimized ArthritoMabTM Antibody Cocktail for the induction of arthritis in C57Bl/6. Using the optimized ArthritoMab Antibody Cocktail, investigators can induce arthritis in C57Bl/6 strains with as little as 2 mg of antibody and see good clinical disease scores as well as pannus formation, bone erosion, hyperplasia and cellular infiltration at the histological level. A detailed whitepaper covering the ArthritoMabTM antibody cocktail, protocols and data using various strains and positive control is available for complimentary download.

The optimized ArthritoMabTM antibody cocktail relies on the same four clones of antibody selected for use in the original cocktail, allowing researchers to continue to obtain comparative data without introducing unknown variables caused by additional antibody clones. The monoclonal antibody clones in the cocktail were selected to bind to C1, J1, U1 and D3 epitopes, which are well documented epitopes associated with arthritis in the collagen-induced arthritis (CIA) model. These epitopes are also spread across the entire CII region (fragments CB8, CB10 and CB11) to encourage better immune complex formation on the cartilage surface for initiation of arthritis.

With the increase in use of transgenic strains such as C57Bl/6 for the study of arthritis, investigators are often faced with low incidence rates in the CIA model. Alternatively, while the Collagen antibody-induced arthritis (CAIA) has been a good alternative for increasing the rates of incidence, often times the amount of antibody required in C57 strains is cost prohibitive. MD Bioproducts has optimized the ArthritoMabTM antibody cocktail enabling investigators to achieve high incidence rates (100%) in C57 strains while controlling costs in the amount of antibody required (as little as 2 mg of Antibody).

For years, the CIA model has been the standard for arthritis studies. Issues such as length of model, staggered disease onset, low disease induction, lab to lab variations, number of administration timepoints and clinical scoring periods caused researchers to look for a viable alternative. The collagen antibody induced arthritis model (AIA or CAIA) using ArthritoMabTM Antibody Cocktail is a reliable alternative providing results in just 12 days, high rates of incidence and synchronized disease onset.

MD Biosciences Offers Monoarthritic Pain Model

Posted by MD Biosciences on Sep 10, 2008 11:23:00 AM


MD Biosciences, a global biotechnology company focused in inflammations and neurology research, is expanding its line of arthritis and pain preclinical services with the addition of the CFA-induced monoarthritic pain model. The model offers advantages over traditional arthritis models in that disease develops in only one joint allowing a comparison to the healthy joint. The quantification of pain associated with arthritis can be useful in elucidating the mechanisms of arthritis as well as evaluating the efficacy of anti-arthritic drug compounds in the discovery phase.

The monoarthritic pain model is a 28-day model with arthritis and subsequent pain present in a single joint. Pain response develops 1 day post-induction. Readouts available are clinical signs and scoring, body weights, mechanical and thermal stimuli, weight bearing, histology and cytokine analysis.

Monoarthritic Pain

In addition to the monoarthritic pain model, MD Biosciences offers the traditional Adjuvant-induced arthritis model that allows for traditional pain measurements as well as a record of spontaneous pain using the Foot Print of Pain method. Other Arthritis models and research reagents include the Collagen Induced Arthritis (CIA) and Collagen Antibody Induced Arthritis (CAIA), ArthritoMab™ Arthritogenic Antibody Cocktail, Collagen Reagents, Collagen Antibodies and Collagen-related ELISA Kits and Assays.

High ArthritoMabTM Antibody Cocktail Activity |18-day RA Model Balb/c Mice

Posted by Amy Clausen on Apr 3, 2007 11:33:00 AM

MD Biosciences releases histology results from an 18-day model of arthritis induced using the ArthritoMab(TM) cocktail of arthritogenic antibodies in Balb/c mice. Results show significant histological changes in the joint of the arthritis group as compared to the normal control group after just 18 days, providing researchers valuable data quickly compared to the traditional collagen-induced arthritis (CIA) model, which can take several weeks or more to produce similar histological results.

Results show significant histological changes in the joint of the arthritis group as compared to the normal control group after just 18 days, providing researchers valuable data quickly compared to the traditional collagen-induced arthritis (CIA) model, which can take several weeks or more to produce similar histological results. Figures 1-3 show the effectiveness of the arthritogenic antibodies, with mean histology scores and staining sections indicating the degree of erosion, hyperplasia and infiltration in the joint of the arthritis group as compared to the control group.

 

ArthritoMab histology

 

 

The ArthritoMabTM Arthritogenic Antibody Cocktail is comprised of 4 monoclonal antibodies to collagen type II (CII) that have been chosen for their epitope specificity. An antibody response to certain epitopes is better associated with arthritis than a response to other epitopes. In the CIA model, the antibody response correlated with arthritis was mainly associated with binding to the epitopes C1, J1, and U1. The ArthritoMabTM monoclonal antibodies were selected to bind to the epitopes C1, J1, U1 and D3 - which are spread over the entire CII region (fragments CB8, CB10 and CB11) encouraging better immune complex formation on the cartilage surface for the initiation of arthritis. The antibody-induced arthritis model using the ArthritoMabTM Arthritogenic Antibody cocktail is a rapid alternative the CIA model.
