The Dance Between Immune System and Stem Cell Health

We named it the  immunoLinkTM 
We have been testing a growing number of Clients with our Quantibody Arrays. Many of of these clients have Autoimmune Disorder Diseases. These range from Rheumatoid Arthritis to Multiple Sclerosis.

These arrays are designed to precisely measure factors or markers(proteins) that are dysregulated by these diseases. We measure the levels of these biomarkers in our Clients’ Blood serum. The arrays have also been used to measure the levels of markers in plasma and cell culture supernatants.

Based on results, we are finding links between immune system and stem cell health. We call this the immunoLink. The link shows that when immune/inflammatory response markers are elevated, markers related to stem cell health are depleted.

Here we see the immune/inflammatory response markers IL-6, MCP-1 and TNF-alpha are elevated in our Clients with autoimmunity (A) vs Healthy Controls (HC). We also see lower levels of G-CSF and GM-CSF in these Clients.

G-CSF and GM-CSF are know to play a role in increasing circulating stem cells. GM-CSF is also know to be secreted by Mesenchymal Stem Cells (hMSCs) AND GM-CSF has anti-apoptotic functions on neurons, and is neuroprotective in animal stroke models while G-CSF has a prominent effect on the differentiation of adult neural stem cells (see: BMC Neuroscience 2007, doi:10.1186/1471-2202-8-88).

To us, the immunoLink means achieving a balance between immune system and stem cell health.

We provide immune system balancing and stem cell activating therapies for our Autoimmune Disease Clients and Children with Autism. We first do baseline and follow on testing (each 6 months) to determine how well the therapies are working. You can now benefit from one of our first Stem Cell Activating Product named Stem-Kine.

Dr. Joe Smarda, an applied immunologist, is user and promoter of Stem-Kine and oh, by the way. He is a European Porsche Cup Champion and pilots our Stem-Kine/Neuromics sponsored race car.

Our goal is to bring the many markers we test to healthier levels. As stem cell transplants become more common, moderating levels of immune/inflammatory response in patients could improve outcomes. If you would like to learn more, you can contact me at pshuster@neuromics.com or 612-801-1007.

Gerry Shaw-Master of World Class Neuronal/Glial Markers

Build it and They will Come

Gerry and One of His Triumph's MCs
Gerry and One of His Triumph’s MCs

I am pleased to profile Dr. Gerry Shaw, a Professor at the University of Florida and also the Head of EnCor Biotechnology Inc.  His story is a guide for incubating and spinning out a successful biotech company (EnCor Biotechnology, Inc.) from a university research laboratory. It should provide an inspiration for fledgling entrepreneurs as the model required little capital investment and has enjoyed profitable growth.

The Backstory

Gerry’s major area of research interest can be summarized as the study of cellular changes resulting from central nervous system damage and disease states. These changes help neuroscience researchers understand the progression and hopefully discover root causes of diseases like Alzheimer’s, Parkinson’s and ALS. Understanding which proteins are involved in particular disease states also has the potential of identifying targets for therapies.

The story starts with Gerry’s Post Doctoral research at the Max Planck Institute for Biophysical Chemistry in Goettingen, in what was at the time West Germany. Here he joined the world renowned laboratory of Klaus Weber and Mary Osborn. This lab had pioneering several important techniques, notably SDS-PAGE for protein analysis and the use of antibodies in immunocytochemistry. Later, after Gerry left the same lab made key contributions leading to the routine use of RNAi in “knock down” of normal cellular proteins. The lab had developed antibodies to tag the subunit proteins of microtubules, microfilaments, intermediate filaments and other cellular proteins, and then used these antibodies to visualize the proteins in immunofluorescence microscopy and on western blots. This enabled researchers to look at changes in the cellular expression of these proteins in powerful new way. These methods have become vital tools for understanding normal cellular function and what happens when cells transition from healthy to diseased states. This lab was an ideal location for Gerry to learn how to make quality monoclonal and polyclonal antibodies. Good antibody reagents are vital for the correct interpretation of immunofluorescence microscopy and western blots, and he was soon supplying his reagents to friends, collaborators and other researchers all around the world. Success is value as antibodies that do not as work as expected waste research time and resources, while quality reagents soon become appreciated and may get to be standard lab reagents.

University of Florida

The University of Florida, in Gainesville imported his expertise when Gerry joined the institute in 1986. Here he continued to make antibodies to Neurofilaments or NFs and other Neuronal-Glial Markers. It’s hard to keep a good thing a secret and Gerry faced growing demand from all over for these reagents. This proved a drain both financially and in terms of time commitment, as well as a significant conflict of interest with his basic biomedical research program.

Primary embryonic hippocampal neurons at 7 days in vitro, were stained with Microtubule Associated Protein-2 (MAP, green) to enable the visualization of the dendritic arbors. These neurons were cultured on top of a monolayer of primary cortical astrocytes, stained with an antibody directed against

Glial Fibrillary Acidic Protein (GFAP, red). The cell nuclei were visualized by staining with 4′,6-diamidino-2-phenylindole (DAPI, blue). BMC Image of the Month October 2010

As a result Gerry took his first entrepreneurial step by selling his most popular reagents in bulk initially to Chemicon (now Millipore-Merck). Like any new business venture, he did not really know what to expect. It should come as no surprise that the reagents sold like hot cakes and the check started rolling in. Other immunoreagent companies approached Gerry and soon he was supplying antibodies to pretty much every major biotechnology vendor.

ABC Biologicals to EnCor Biotechnology Inc.

Success breeds success and as sales increased over the 1990s, it was time to form an independent business and so ABC Biologicals Inc. was incorporated in 1999 initially to buy equipment and develop licensing agreements. Since Gerry had income from sales, he was in the unusual and enviable position of not needing grants, investors, loans or cash from any other source, and so could proceed with almost total independence. The company was renamed EnCor Biotechnology Inc. in 2002, and at the same time moved into the Sid Martin Biotechnology Incubator, a lab dedicated to commercialization of intellectual property generated by the faculty of the University of Florida. The University of Florida is unusually experienced at this and is well known for launching Gatorade, Trusopt and many other products. After 4 years EnCor “graduated” from the Incubator and now occupies a facility in Gainesville. The company now has almost 100 products with many more under development. This is good news for the Neuroscience community.

The EnCor-Neuromics Connection

Neuromics provides EnCor Biotechnology reagents to researchers studying neuro-degeneration, neuro-regeneration, neuro-development, neural stem cells, mood disorders, brain injury and spinal cord injury. My customers have found EnCor’s reagents to be rock solid and versatile.

In addition, Gerry and his team have proved adept at culturing our E18 hippocampal neurons and ESC derived hN2TM primary neurons. This is a big plus as we can actually see how the cells and markers could resonate together for use in cell based assays.

Futures

I am excited by the glimpse of the future that Gerry shared. We can expect many new, novel and important markers in the coming months and years. In addition, he will be manufacturing various Enzyme-linked immunosorbent assays (ELISA). These kits have the potential to help clinicians diagnose the early onset of diseases like ALS, Parkinson’s and Alzheimer’s.

For example, his company currently sells an ELISA kit for sensitive detection of Phosphorylated Neurofilament-H (pNF-H). Expression of this protein is up regulated in a variety of damage and disease states, and can be used to accurately quantify this up regulation. The kit can also detect pNF-H in the sera and spinal cord fluid (CSF) of animals with spinal cord and brain lesions. This protein is not normally found in sera or CSF, so its presence indicates recent axonal injury as a result of either damage or disease. This suggests pNF-H is a useful biomarker of neuronal and more specifically axonal injury or degeneration, a suggestion supported by a growing list of basic science publications on various animal models and patient types from Gerry’s research lab (e.g. Shaw et al. 2005, Lewis et al. 2008, Boylan et al. 2009, Lewis et al. 2010).

Given the capabilities of EnCor’s markers, the development of more kits is coming. There could be a day in the not distant future where they give clinicians tools to better diagnose and monitor serious neurodegenerative diseases, leading to better disease treatment and management.

I will keep you informed on Gerry’s and EnCor’s future developments.
