Method of Producing Immortalized Primary Human Keratinocytes for HPV Investigation, Testing of Therapeutics, and Skin Graft Generation

One of the major limitations of using cultured keratinocytes for research studies is that primary keratinocytes senesce after a few passages. Keratinocytes from specific anatomical sites are also difficult to culture. Scientists at the NIH have demonstrated that primary keratinocytes, from several anatomical sites, when treated with a small-molecule inhibitor of the ROCK protein maintain a proliferative state and become immortal without genetic modification to the cells.

Optical Trap Methods to Determine the Viscoelastic Properties of Biological Materials

Optical traps (optical tweezers) have a focused laser beam able to trap a small bead at its focus, and are used to measure the microrheology of gels and other materials. They have recently been used to characterize properties of living cells, however issues of image spatial resolution and limited depth of interrogation have prevented application of an optical trap to measure microrheological (flow of matter) properties in complex (non-uniform) materials, such as multi-cellular systems or living organisms. 

Human Monoclonal Antibodies to Generate Chimeric Antigen Receptor (CAR) T-cells to Treat Patients with Advanced Clear Cell Renal Cell Carcinoma (ccRCC).

This technology includes six human monoclonal antibodies (mAbs) that target tumor antigens derived from the CT-RCC HERV-E (human endogenous retrovirus type E) to generate Chimeric Antigen Receptor (CAR) T cells to treat patients with advanced clear cell renal cell carcinoma (ccRCC). These mAbs were identified from Adagene Inc’s human antibody phage library, and data show that majority of these mAbs only bind to CT-RCC HERV-E+ ccRCC cells, which express TM but not CT-RCC HERV-E non-expressing ccRCC cells nor non-RCC cells.

A Target for the Development of Diagnostics and Therapeutics for Abnormal Hematopoiesis

The zinc finger protein ZFP36L2 has been shown by the inventors to play an essential role in hematopoiesis, a process that is dysregulated in hematological cancers, anemia, and other conditions. Thus, ZFP36L2 has promise for use in a diagnostic test to detect abnormal hematopoiesis, or as a target for the development of therapeutics to treat abnormal hematopoiesis.

Method to Detect and Quantify In Vivo Mitophagy

This technology includes a transgenic reporter mouse that expresses a fluorescent protein called mt-Keima, to be used to detect and quantify in vivo mitophagy. This fluorescent protein was originally described by a group in Japan and shown to be able to measure both the general process of autophagy and mitophagy. We extended these results by creating a living animal so that we could get a measurement for in vivo mitophagy. Our results demonstrate that our mt-Keima mouse allows for a straightforward and practical way to quantify mitophagy in vivo.

System for Automated Anatomical Structures Segmentation of Contrast-Enhanced Cardiac Computed Tomography Images

This technology includes a fully automatic 3D image processing system to segment the heart as well as other organs from contrast-enhanced cardiac computed tomography (CCT) images. Our method detects four cardiac chambers including left ventricle, right ventricle, left atrium, right atrium, as well as the ascending aorta and left ventricular myocardium. It also classifies noncardiac tissue structures in the CCT images such as lung, chest wall, spine, descending aorta, and liver.

Human Monoclonal Antibodies That Target the RH5 Complex of Blood-Stage Plasmodium Falciparum

249 million people were afflicted with malaria in 2022. There are five Plasmodium parasite species that cause malaria in humans. Of the five, Plasmodium falciparum causes most of the incidence of human disease. Most advanced malaria vaccine candidates can confer only partial, short-term protection in malaria-endemic areas. The pathogenesis of malaria is associated with blood-stage infection and antibodies specific to the parasite blood-stage antigens may be able to control parasitemia.

Engineered Human Induced Pluripotent Stell Cell (iPSC) Lines for Multiple Therapeutic and Diagnostic Uses

This technology includes ten engineered human induced pluripotent stem cell (iPSC) lines with reported genes inserted into safe harbor sites for use in therapy and diagnostic screening assay development as well as basic stem cell biology research. These cell lines have the potential to differentiate into all cells in the body, and theoretically can proliferate/self-renew indefinitely.

A Rapid Method for Producing Antibodies

Antibodies are specialized proteins produced by the immune system which target and neutralize foreign materials, such as viruses or bacteria. Antibodies have a variety of useful applications in diagnostics, therapeutics, and as research reagents. Despite their widespread use there is no standard method to produce antibodies, and currently available methods are labor and time intensive.

Intralipid as a Contrast Agent to Enhance Subsurface Blood Flow Imaging

This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.
