This technology includes a family of small-molecule antagonists that selectively block the 5-HT_2B serotonin receptor—an upstream driver of tissue-remodeling—to address fibrotic, cardiopulmonary and related disorders. Built on a conformationally-locked “(N)-methanocarba” nucleoside scaffold, the compounds show nanomolar potency, >30–400-fold selectivity over the closely related 5-HT_2C receptor, and favorable oral bioavailability in rodents.

This technology includes the creation and use of A3 adenosine receptor (A3AR)-selective agonists for treating chemotherapy-induced peripheral neuropathy, chronic neuropathic pain, rheumatoid arthritis, psoriasis, and other conditions. A3 receptors for adenosine are found in most cells and endogenous activation of the A3 receptors can result in apoptosis, thereby relieving the inflammation or targeting a tumor. A3AR agonists have been a promising strategy for the treatment of various diseases.

Currently available topical antibiotic formulations effectively eliminate bacteria at a wound site. Eliminating bacteria in the wound also eliminates the molecular signals present in bacterial DNA that stimulate the immune system's wound healing processes. Without these signals, the rate of wound healing is diminished.  

Spatial proteomics and transcriptomics are fast-emerging fields with the potential to revolutionize various branches of biology. In the last five years, various multiplex immunofluorescence and immunohistochemistry imaging methods have been developed to stain 5-60 different protein markers in a given tissue. Nonetheless, most of these techniques are iterative and can image a maximum of 3-8 markers in a single cycle, resulting in processing time of several hours to days.

Many biological and clinical procedures require functional validation of a desired cell type. Current techniques to validate rely on various assays and methods, such as staining with dyes, antibodies, and nucleic acid probes, to assess stem cell health, death, proliferation, and functionality. These techniques potentially destroy stem cells and risk contaminating cells and cultures by exposing them to the environment; they are low-throughput and difficult to scale-up.

Problem: Cryopreservation is a process where living biological materials like cells, tissues, and cell therapies (which are susceptible to damage caused by unregulated chemical kinetics) are preserved by cooling to very low temperatures in the presence of specific cryopreservation media that protects the biological material from damage. In order to be used, the biological material ideally should be thawed in a controlled manner that minimizes damage and desirably brings the material back to a viable state.

It is well documented in literature that activation of RXFP1 by relaxin induces: 1) up-regulation of the endothelin system which leads to vasodilation; 2) extracellular matrix remodeling through regulation of collagen deposition, cell invasiveness, proliferation, and overall tissue homeostasis; 3) a moderation of inflammation by reducing levels of inflammatory cytokines, such as TNF-a and TGF-b; and 4) angiogenesis by activating transcription of VEGF.

Summary:

The National Center for Complimentary and Integrative Health (NCCIH) seeks licensees and/or commercial partners to develop topical formulations of margaric acid to treat allodynia, neuropathy, and pain caused by chronic inflammation.  

Description of Technology:

Gel materials, particularly hydrogels, typically lose their mechanical strength and stiffness as they swell. This property  limits their use in both biological (e.g., cartilage and ECM repair) and non-biological (e.g., sealant) applications. Innovative materials in both medical and non-medical application areas are sorely needed.

Summary:

The National Cancer Institute (NCI) seeks co-development partners and/or licensees for polymer-cast inserts for cell histology and microscopy; a system for high throughput three-dimensional (3D) cell culture and screening microscopy.
