Nucleic Acid Nanoparticles (NANP) and Methods of Using Same for Controlled Immunomodulation

The technology is directed to compositions and methods of designing nucleic acid nanoparticles (NANPs) composed entirely of DNA, RNA, or DNA and RNA to achieve desirable immunostimulation and decrease undesirable effects on the immune system by changing the composition of the NANP. Benefits of the invention include the desirable activation of the immune system by these particles to increase the efficacy of vaccines and immunotherapies.

Interleukin 24 (IL-24) to treat inflammatory diseases

Proinflammatory T-helper 17 cells (Th17) play important roles in host immune defense against infection, but uncontrolled activation of these cells, known as the Th17 response, may cause autoimmune and autoinflammatory diseases (uveitis, multiple sclerosis, rheumatoid arthritis, and Crohn’s disease) through the effects of Th17 lineage cytokines (such as, IL-17F, IL-22 and GM-CSF). Importantly, IL-17A (a proinflammatory cytokine) represses other Th17 lineage cytokines by upregulating the regulatory cytokine IL-24.

A peptide hydrogel for use in vascular anastomosis

In collaboration with surgery specialists from Johns Hopkins University, researchers at the National Cancer Institute (NCI) developed novel hydrogel compositions and methods of using them in the microsurgical suturing of blood vessels, which is particularly beneficial for surgeons in whole tissue transplant procedures. The lead candidate electropositive hydrogels, called APC1, was demonstrated in anastomosis mice models to be well tolerated, biocompatible, and non-toxic.

Fatty Acid Derivatives and Their Use for the Treatment and Prevention of Autoimmune, Inflammatory, and Pain Disorders

The discovery and selection of suitable compounds for the treatment and prevention of autoimmune, inflammatory, and pain disorders is a significant challenge. Researchers at National Institute of Aging (NIA) mitigated this issue. They discovered and synthesized numerous novel fatty acid derivatives (novel small molecules) that may ameliorate these conditions and provide treatment options for these disorders. In a relevant rat model, the fatty acid derivatives developed by NIA demonstrated:

MADCO-Accelerated Multidimensional Diffusion MRI

Although multidimensional diffusion/relaxation NMR experiments are widely used in materials sciences and engineering applications, preclinical and clinical MRI applications of these techniques were not feasible. Moreover, higher-field MRI scanners posed another obstacle to translation of this NMR method. Their specific absorption rate (SAR) limits the use of multi-echo or CPMG pulse trains, so that the large amounts of data required by these methods cannot be collected in vivo due to exceedingly long scan times.

NSAIDs that Assist the Treatment of Human Diseases

Non-steroidal anti-inflammatory drugs (NSAIDs) have long been used to treat a variety of inflammatory conditions.  Many of these conditions, such as cancer or arthritis, require long term use of the NSAIDs due to the chronic nature of the disease.  However, the NSAIDs in current use have toxicities associated with their long-term use that hinder their use for these chronic conditions.    

Use of a Modified Adaptor Molecule LAT to Improve Immunotherapy for Cancer and Other Diseases

One problem with the development of immunotherapy for cancer or other diseases is the inability to stimulate a sufficient immune response in patients to tumor associated antigens. The Linker Adapted for T Cell Signaling molecule (LAT) has been shown to be an important molecule in T cell signaling. The inventions described and claimed in this patent application illustrate a new supportive role for LAT which may be harnessed to improve a patient's immune response to tumor-associated antigens.
