Visualizing Endogenous Synaptic Proteins in Living Neurons

The recently published method is based on the generation of disulfide-free “intrabodies”, a structure from the 10th fibronectin type III domain known as FingRs. These affinity molecules were fused to GFP for direct fluorescence miscroscopy. The FingRs do not need di-sulfite bonds and are therefore better folders in mammalian cells. Specifically, a library was screened with in vitro display to identify FingRs that bind two synaptic proteins, Gephyrin and PSD95. After the initial selection, the researchers from USC secondarily screened binders using a cellular localization assay to identify potential FingRs that bind at high affinity in an intracellular environment. As it turned out, only 10-20% of the original positive clones bind well inside the cells, suggesting this type of further screening was a critical step.

The expression of intrabody is transcriptionally regulated by the target protein through a ZFN-repressor fusion. This transcriptional control system matches the expression of the intrabody to that of the target protein regardless of the target’s expression level. This design virtually eliminates unbound FingR, resulting in very low background that allows unobstructed visualization of the target proteins. As result, the FingRs presented in this study enabled live cell visualization of excitatory and inhibitory synapses, and apparently without affecting neuronal function.

Technically, the reason to use in vitro mRNA display was required by the need to use a large library (>10exp12, beyond the limit of the more commonly used phase display) to find good binders. A similar visualization system can be established using more potent affinity domains such as the VHH single-domain antibodies that have only one, sometimes dispensable, di-sulfite bond. The VHH domain nanobodies can be more easily isolated from camelid animals. Another improvement to the visualization system can be made by using stronger, superresolution-ready FPs such as mNeonGreen or mMaple to enable single molecule imaging, which is particularly interesting for studying synapses and applied to the BRAIN initiative.

Allele Biotech Receives $200,000 Grant to Update Its mRNA Reprogramming Commercial Products and Services

On June 10, 2013 Allele received an SBIR award from the National Institute of Drug Abuse (NIDA/NIH) entitled “Revolutionary Technology for Efficient Derivation of Human iPSCs with Messenger RNA”. The goal of the proposed project is to provide to the biomedical research market an advanced reagent kit and services for highly efficient reprogramming of high quality human induced pluripotent stem cells (iPSCs). At the core of this kit is the Allele team’s recent development transcribed messenger RNA (mRNA). Compared to other reprogramming methods, such as lentivirus, Sendai virus, protein, small molecules or any combinations of these reagents, our new generation of the mRNA method often requires less than half the time while sometimes achieving “bulk conversion” efficiency.

While the Allele reprogramming technology was designed for clinical use as the process is feeder-free, xeno-free, chromosome integration-free, as well as without the need for cell splitting, PI, Dr. Jiwu Wang states, “Our purpose of executing the NIH-funded research it to make our method so easy that any researcher can integrate iPSC into his or her projects.” In addition to the extremely high efficiency, mRNA-generated iPSCs should also be more stable because there are no genetic alterations, more uniform among all clones as there is no clonal event, and ultimately suitable for future autologous cell therapy now that creating iPSCs from patient tissue cells should no longer be the rate-limiting steps.

Allele’s business model is to provide cGMP-grade iPSCs to pharmaceutical companies and perform large scale reprogramming by partnering first with university-affiliated hospitals. Great progress has been made in both directions, which has prompted the initiation of a cGMP unit within Allele’s newly acquired building in San Diego.

NIDA Branch Chief, Jonathan D. Pollock, Ph.D., Encourages SBIR/STTR Grants on Reagent Kits Including iPSC

“We’re interested in areas of genetics, in terms of smoking cessation, pharmacogenomics, treatment of substance abuse, and particularly right now, issues related to prescription substance abuse,” Jonathan D. Pollock, Ph.D., chief of the Genetics and Molecular Neurobiology Research Branch at NIDA’s Division of Basic Neuroscience and Behavioral Research, told GEN.

In addition to that solicitation, Dr. Pollock said, the branch is interested in supporting commercialization and development of products, resources, and services through SBIR/STTR relevant to brain research. They include protein capture reagents, proteomics, genomics, pharmacogenomics, molecular diagnostics, nanotechnology, gene delivery and viral vectors, identification of RNA and DNA sequences in formalin fixed nervous tissue, shRNA, microfluidics, epigenetics diagnostics, therapeutics, and tools to detect epigenetic modifications.

The branch is also looking to support commercialization and development of biomarkers, optogenetics, reagents for iPS and neural stem cells, technologies to uniquely barcode cell types, improved super resolution microscopy methods, in vivo gene expression imaging, automated sectioning, image acquisition and 3D reconstruction of electron micrographic sections, genetically encoded markers for electron microscopy, and “big” genomic and proteomic data, including data visualization, data contextualization, and data analysis.

“What we’re really looking for is products that you could basically commercialize coming out of research. These can be things that are either products or services. I think that there are opportunities, particularly for groups of individuals that have an idea, IP, and want to have a startup company.”

SBIR/STTR grants account for 2.8% of NIDA’s roughly $1 billion annual budget. NIDA spent $26.679 million on SBIR and STTR in fiscal year 2012, which ended September 30—up from $26.497 million in FY 2011. The number of SBIR/STTR research projects grants rose to 56 in FY 2012 from 44 a year earlier, according to the GEN article.

Allele Biotech’s CEO, Jiwu Wang, Ph.D., has worked with Dr. Pollock on a previous, VHH nanobody-related project under the NIDA SBIR program. He has just submitted a SBIR grant application based on Allele’s recently published mRNA-based reprogramming technology, after discussion with Dr. Pollock.

The NIH is one step closer to be short of $260 million from its 2011 budget

The National Institutes of Health (NIH) 2011 budget will be cut by $260 million in the budget that the House has just passed based on the last minute pact reached last Friday to avoid federal government shut down.

The NIH’s 2011 budget will be $30.7 billion, down 0.8% from its 2010 budget of $30.9 billion, according to news releases that can be found from various sources. Previously, the President proposed a $32.1 billion budget for the NIH and the House of Representatives allocated $29.4 billion to the agency. President Obama asked for a $1 billion increase for the NIH in 2012, which will be in new debate to start immediately. Chances are the 2012 budget for the agency will be less than what the administration wanted.

Combined with “the cliff effect” from the ending of the stimulus money the NIH has epically managed since 2009 to fund extra research projects, the negative growth of the NIH budget could mean less academic positions and tighter lab budgets ahead. Cutting-edge technology and cost effectiveness will be the key for survival of the fittest in the biomedical research jungle.

NIH Announces SHIFT SBIR Grants to Help Academic Researchers Get Jobs in Biotech

The National Institutes of Health (NIH) just announced a new type of Small Business Innovative Research (SBIR) grants. Called SHIFT SBIR, these grants are designed to “(1) to foster research that is translational in nature and (2) to transform academic scientific discoveries into commercial products and services,” according to the NIH announcement, and to also facilitate licensing of intellectual properties from academic institutions as well as promote better access to academic resources. The PI transitioning from the academic institution must be primarily employed by his/her research institution at the time of application and must be primarily employed (more than 50% time) by the company by or at the time of award.

One very attractive aspect of these grants is that they mean more money than standard SBIR grants. Up to $200,000 total costs per year and time periods up to 2 years may be requested for Phase I. Well-justified budgets up to $750,000 total costs per year and time periods up to 3 years may be requested for Phase II. That is sufficient for a good researcher to build a team to do research in one direction within pretty much any small company setting.

A little background about SBIR grants: SBIR programs sponsored by federal funding agencies including the NIH, NSF, DOE, FDA, the military departments, etc. have been a major source of funding for many biotech companies like Allele Biotech during their startup phases. SBIR grants can also be used to facilitate continued research and help business expansion even as the company grows. As an example of the effects of SBIR grants, Allele Biotech obtained 5 such grants from 2000 to 2003 and built a company from just ideas to one with a patent in RNAi, an out-licensing deal with Promega, a product line in oligo synthesis, and a structure that helped launch currently ~1,500 products since 2004. We then carried out 2 more SBIR contracts for the NIH from 2007 to now, which moved us into the field of special antigen production, iPS using Bacmam systems, viral packaging services, and hopefully more advanced antibodies in the pipeline.

The link to the full NIH announcement is here.
