Induced Pluripotent Stem Cells Derived from Patients with CEP290-associated Ciliopathies and Unaffected Family Members

Approximately one-third of non-syndromic retinal dystrophies involve a defect in a ciliary protein. Non-syndromic retinal ciliopathies include retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, macular dystrophy, and Leber-congenital amaurosis (LCA). Many CEP290-LCA patients also exhibit auditory and olfactory defects. Induced pluripotent stem cells (iPS) cells were derived from patients with LCA and unaffected relatives. 
The National Eye Institute (NEI) seeks research collaborations and/or licensees for the use of these iPS cells.

Inducible Activation Nucleic Acid Hybrid Switch for Conditional Generation of Oligonucleotides

Gene therapy research has yielded FDA-approved treatments for an array of diseases. However, challenges facing nucleic-acid based therapeutics include non-specific delivery and degradation of the nanoparticles. NCI investigators have developed a solution to address these challenges in their novel nucleic-based therapy based on the conditional activation strategy. 

Peptide Hydrogels for Rate-Controlled Delivery of Therapeutics

Hydrogels represent an attractive controlled drug-delivery system that have been used in various clinical applications, such as: tissue engineering for wound healing, surgical procedures, pain management, cardiology, and oncology. High-water content of hydrogels confers tissue-like physical properties and the crosslinked fibrillar network enables encapsulation of labile small molecule drugs, peptides, proteins, nucleic acids, proteins, nanoparticles, or cells.

Molecular Classification of Primary Mediastinal Large B Cell Lymphoma Using Formalin-Fixed, Paraffin-Embedded Tissue Specimens

Primary mediastinal B-cell lymphoma (PMBCL) is an aggressive type of non-Hodgkin lymphoma that mostly occurs in people between the ages of 30-40. It accounts for 5-7% of all aggressive lymphomas. The diagnosis of PMBCL is challenging as the histological features of PMBCL overlap with diffuse large B-cell lymphoma (DLBCL), another most common type of non-Hodgkin lymphoma. Available evidence suggests that PMBCL responds much more favorably to the DA-EPOCH-R chemotherapy regimen than to the standard R-CHOP regimen used to treat DLBCL.

A Viral Exposure Signature to Define and Detect Early Onset Hepatocellular Carcinoma

Early detection of liver cancer, such as hepatocellular carcinoma (HCC), is key to improve cancer-related mortality. More than 800,000 people are diagnosed with this cancer each year throughout the world. Liver cancer is also a leading cause of cancer deaths worldwide, accounting for more than 700,000 deaths each year. Currently, millions of Americans and possibly billions in the world are considered at risk for developing liver cancer.

Design and Biological Activity of Novel Stealth Polymeric Lipid Nanoparticles for Enhanced Delivery of Hydrophobic Photodynamic Therapy Drugs

Nanoparticles such as lipid-based nanoparticles (LNPs) represent a relatively new era of targeted drug delivery systems wherein these biocompatible particles can carry the drug(s) of interest to a specific tumor site. The new generation of nanoparticles, known as stealth nanoparticles, are engineered to have a coating of polyethylene glycol polymer (PEG) or other glycolipids that enable them to evade the immune system and have a longer circulation lifespan as well as improved bioavailability to diseased tissue and reduced non-specific toxicity.
 

Genetically Modified Hematopoietic Stem And Progenitor Cells (HSPCs) And Mesenchymal Cells As A Platform To Reduce Or Prevent Metastasis, Treat Autoimmune And Inflammatory Disorders, And Rebalance The Immune Milieu And Dysregulated Niches

Cancer cells can spread to various regions in the body in a process called metastasis which is associated with non-responsive to treatment and thus reduced survival. Identifying the markers of metastasis has been a major concern in the field of cancer diagnosis and therapy. Interestingly, research has shown that there is an increase in myeloid progenitors and myeloid cells at various stages of metastasis in an attempt by the immune system to  suppress cancer cells. This presents a promising technology for cancer immunotherapy.

New Class of Immunotoxins with Extended Half-Life and High Anti-Tumor Activity

Recombinant immunotoxins (RITs) constitute a promising solution to hematologic cancers (e.g., Multiple Myeloma [MM]). RITs are chimeric proteins composed of a targeting domain fused to a bacterial toxin. Upon binding to a cancer cell displaying the target antigen, RITs are internalized, metabolized and the released toxin kills the cell. While highly active and effective, current RITs have short half-lives, requiring them to be used in high concentrations for treatment. At such high concentrations, RITs may show nonspecific activity and kill healthy cells.
