Serum-free cell culture media design is important because it offers the opportunity to construct chemically defined media that possess greater batch-to-batch reproducibility and clinically compatible reagents; benefits not necessarily associated with serum-containing media.  As such, it is an ideal method for producing media for the growing cell therapy market segment where high quality and reproducibility standards influence clinical translation.  However, the use of defined chemical factors often creates a complex, large-scale optimization problem where the number of possible combinations of factors across different dose concentrations creates a search space so large that only a millionth or less of it can be sampled.  Consequently, this renders traditional media optimization techniques ineffective and necessitates the development of new techniques to handle this problem.

This technology includes a suite of inventions, including a fully-functional coded-exposure-pixel (CEP) camera prototype, a novel programmable CMOS sensor, and a method for adaptive adjustment of exposure of every pixel, based on changes in the brightness of the scene for that pixel to extend dynamic range at native sensor resolution.

Dental diseases are often caused by a perturbation in the balance of the oral microbiome.  Bacterial species that confer positive health benefits may reduce in number shifting the oral composition to more virulent strains and increasing the chance of disease.  This harmful shift can be reversed by using commensal bacteria to target and crowd out these pathogens.  Researchers at the University of Toronto have isolated a Streptococcus salivarius strain (SALI-10) that can interfere with the growth of periodontal pathogens.

The platform allows for clinical-grade data analysis from wearable sensors (e.g. smartwatches, mobile devices) through proprietary machine learning (ML)-based algorithms that extract clinically relevant data and filter out unreliable sensor data. This platform can provide real-time feedback on patient health, generate more accurate predictions, and enable actionable insights and recommendations to improve care.

Obesity has increased to pandemic levels and is associated with an increased risk of metabolic diseases, including type 2 diabetes mellitus (T2DM), cardiovascular disease and cancer.  While the most effective means to reduce weight is healthy eating and exercise, adherence to these recommendations are a challenge, especially in individuals with a high body weight or BMI >30.  Alternatives to these solutions include anti-obesity therapeutics and supplements. Limited therapeutic options are approved by the FDA, such as Glp-1R agonists, but they are restricted to high BMI patients, are costly for insurers/individuals, have limited efficacy or have unpleasant side effects. Similarly, several supplements are available, but none are regarded as being efficacious unless combined with diet and exercise.  Consequently, an unmet need in effective weight loss management exists especially for those individuals in the BMI range of 25 – 32 who want to lose a few pounds to avoid the progression towards metabolic disease without altering their current lifestyle.

Plant parasitic nematodes are microscopic worms that impose a severe economic burden on the agricultural industry.  To curtail their effects, chemical agents that reduce the fitness of nematodes, called nematicides, have become widespread throughout the world.  However, the ecological toxicity and human safety of these chemicals has posed a problem and resulted in bans to some of the most used nematicides. Researchers at the University of Toronto have developed the first bioactivatable nematicides. 

HDAC6 plays an important role in neurological, inflammatory, and other diseases; and thus is an important target for therapeutic intervention.  To date, there are no FDA-approved HDAC6-targeting drugs and most pipeline candidates suffer from poor target engagement, inadequate brain penetration, and low tolerability. There are five HDAC6 clinical candidates for the treatment of mostly non-CNS cancers as their pharmacokinetic liabilities exclude them from targeting HDAC6-implicated neurological diseases, urging for the development to address these challenges. They also demonstrate off-target toxicity due to limited selectivity, leading to adverse effects in patients. Selective inhibitors have thus been the focus of development over the past decade, though no selective and potent HDAC6 inhibitor has yet been approved to date.

Parkinson’s disease is a disabling and progressive neurological disorder characterized by degeneration of dopamine-producing neurons. Current therapies to replace dopamine are only symptomatic and are associated with considerable complications as the disease progresses. No disease-modifying therapies that slow or stop disease progression are available or likely to emerge soon. With Parkinson’s disease affecting over 6 million people worldwide and being the fastest growing neurological disease, this is a huge unmet need in neurodegeneration.

Complex multi-protein clusters play vital roles in many aspects of biology. Deregulation of these clusters may lead to several human diseases including cancer, cystic fibrosis, cardiovascular and neurodegenerative disorders. This technology uses a bait (protein of interest) - prey (candidate molecules) system to detect and identify novel interacting partners in a mammalian genetic system. Dr Stagljar has built upon his initial patented Membrane Yeast Two-Hybrid (MYTH) invention to propose a unique platform to discover new target molecules for research and drug development purposes. This technology provides a new tool to examine membrane proteins in their natural environment of the human cell. It is sensitive enough to detect minor changes upon the introduction of drugs and thus should prove useful in the development of therapeutics, especially for cancer and neurological diseases.

This invention is a novel formulation for biocompatible microemulsions for use as delivery vehicles for active ingredients in transdermal, topical and oral delivery. The formulation is based on five basic ingredients: lecithin (extracted from soybean or other source); a lipophilic additive such as long change alcohol or long chain fatty acid, monoglyceride, or sorbitol ester; a hydrophilic additive containing C6-C9 fatty acids partially saponified; a C8-C20 fatty acid ester; and water. Particular combinations of these ingredients, at specific ratios, yield thermodynamically stable microemulsions capable of increasing the solubility (in isotonic solutions) of hydrophobic drugs such as lidocaine, and alpha-tocopherol acetate by more than 20 fold.

Point-of-care (POC) testing involves the rapid detection of analytes near patients and enables quick medical decisions that can improve disease diagnosis, monitoring, and management.  Cell free systems have been particularly successful as POC diagnostics by utilizing gene-circuit based sensors outside the physiological constraints of cells, which accelerates the product development cycle and enables easy storage, distribution, and use.  However, most demonstrations to date rely on fluorescent reporter proteins which require multi-well plate reader assays, leaving the technology for all practical purposes stuck in the laboratory. In line with this promise of cell free gene-circuit sensors, we have developed a cheap and accessible detection method at the University of Toronto.

Point-of-care (POC) testing involves the rapid detection of analytes near patients and enables quick medical decisions that can improve disease diagnosis, monitoring, and management.  Cell free systems have been particularly successful as POC diagnostics by utilizing gene-circuit based sensors outside the physiological constraints of cells, which accelerates the product development cycle and enables easy storage, distribution, and use.  However, most demonstrations to date rely on optical reporter proteins which require equipment contained in centralized labs and which offer limited multiplexing capabilities.  To overcome these limitations, researchers at the University of Toronto have developed a direct gene-circuit/electrode interface that allows point-of-care detection of RNA.

Targeted protein degradation (TPD) is an alternative approach to conventional paradigms (e.g. small molecule inhibitors) that target disease.  In this technique, a PROteolysis TArgeting Chimera (PROTAC) or a molecular glue is used to initiate the degradation process of the targeted protein.  While these two molecular classes are mechanistically distinct, they both enable degradation by recruiting an E3 ligase, an enzyme which enables the transfer of the ubiquitin tag needed for proteasome-mediated degradation.  One obstacle to the development of these treatment modalities is that the two E3 ligases largely used with this approach only work with some proteins.  Thus, identification of new E3 ligases can increase the disease targeting space of targeted protein degradation therapeutics.

Precisely controlled regulation of gene expression in cells, tissues, and organisms is one of the major challenges in tissue engineering, cell-based therapies, and gene therapy. Controlled gene expression in cells is achieved either by exogenously introducing cDNAs by transfection or viral transduction, or by introducing sequence-specific transcriptional regulators. These regulators include zinc-finger nucleases, transcription activator like effectors (TALEs), or enzymatically inactive Cas9 (dCas9) which are fused to transcriptional activation or repression domains to achieve the desired effect on gene expression. Of these techniques, CRISPR activation (CRISPRa), based on the fusion of inactive Cas9 (dCas9) to various trans-activation domains, is a powerful platform for activating gene expression. However, non-human activators (e.g. VP16) can elicit an immune response necessitating the development of human activators of comparable and tunable efficacy.

Self-Micro Emulsifying Drug Delivery System (SMEDDS) is an advanced lipid-based delivery system composed of an isotropic mixture of surfactants and oils that rapidly and spontaneously assemble into microemulsions (5-150 nm) upon exposure to water with a gentle agitation.  These features enable enhanced delivery and quick absorption of hydrophobic bioactive compound through gastrointestinal tract and epithelial tissues.  SMEDDS are easy to manufacture, offer high loading capacities, and have a long shelf life.

Parasitic nematodes are a major problem in agriculture where their infection of livestock and parasitization of plants are a threat to food security and result in billions of dollars of lost productivity.  Several classes of nematicides, compounds that are toxic to nematodes, have been approved and successfully integrated into the food generation process.  However, two problems with current nematicides are increasing resistance to their effects and serious concerns with their environmental impact, the latter of which has led to withdrawal of commercially successful nematicides from general use. Researchers at the University of Toronto have discovered two small molecule scaffolds for potential use as nematicides in agricultural applications.
