Researchers at UCI have developed an innovative method for assesses coronary artery stenosis and microvascular disease that is both accurate and non-invasive.

New Non-Invasive Markers To Assess Efficacy Of Anti-Integrin Therapies

Inflammatory bowel disease is a chronic disease, which affects the lower bowel parts or the entire GI tract, causing symptoms like abdominal pain, diarrhea, fever and weight loss. An estimated two million people in North America suffer from IBD seemingly caused by an overactive mucosal immune system. Crohn’s Disease and ulcerative colitis (UC) are the major groups of inflammatory conditions that make up IBD and are incurable, serious and chronic organic diseases of the intestinal tract.   Recently, anti-integrin monoclonal antibodies have been approved by the FDA as therapeutic agents for treatment of IBD and there are a number of phase three clinical trials ongoing using monoclonal antibody therapy. The immune system responds to the inflammation that is part of the immunopathology of IBD and acts by recruiting inflammatory cells to the intestinal lesions.  Intergrins, specifically alpha 4-β7, plays a key role in mediating leukocyte trafficking from the circulation to the vascular endothelial barrier in gut-associate lymphoid tissue with the ligand MAdCAM-1. The use of anti-integrin therapy targeting alpha 4-β7 reduces the number of immune cells to the gut endothelium. However, the precise identity of the cell subsets depleted from the intestinal lamina by these anti-integrin drugs have not been identified. Thus, there is an unmet need to further develop tools that allow for the identification of the critical effector cell subsets targeted by these drugs in the intestine.

Imaging Modalities and Methods for Enhanced, Label-free Histopathology During Surgery

Researchers at the University of California, Davis have developed new techniques capable of producing near real-time tissue analysis with quality and accuracy attributes comparable to traditional Haemotoxylin and Eosin (H&E) histopathology methods.

Detecting Cardiovascular Disease Using Noninvasive Imaging of the Eye

Cardiovascular disease is the leading cause of mortality and disability worldwide. It is also prevalent, affecting 9% of the population over 20 years of age. Patients with cardiovascular risk factors can reduce their risk of developing catastrophic cardiovascular events such as heart attack and stroke through lifestyle modification and medications. Unfortunately for many, the disease may go undiagnosed until the occurrence of serious events. Identifying biomarkers of subclinical ischemia can help identify patients with occult cardiovascular disease.

Human-Centered Drug Discovery: A Methodology To Identify And Validate High-Value Therapeutic Targets For Human Diseases

Modeling diseases as networks has helped simplify an otherwise complex web of multi‐cellular processes; however, an exclusive reliance on symmetric relationships in these networks overlooks the existence of disease continuum states and loses information relevant to pathogenesis and for the development of therapeutics. Network‐based analyses severely influenced by symmetric analyses have helped formalize Network Medicine as a field and deliver many successes, but drugs that can predictably re‐set the network in complex multi‐component diseases are yet to emerge.

A Microplatform For Performing High Throughput, Multiplexed Assays On Adherent Cells

Systems and methods are providing for performing high-throughput, programmable, multiplexed assays of biological, chemical or biochemical systems. Preferably, a micro-pallet includes a small flat surface designed for single adherent cells to plate, a cell plating region designed to protect the cells, and shaping designed to enable or improve flow-through operation. The micro-pallet is preferably patterned in a readily identifiable manner and sized to accommodate a single cell to which it is comparable in size. Each cell thus has its own mobile surface. The cell can be transported from place to place and be directed into a system similar to a flow cytometer. Since, since the surface itself may be tagged (e.g., a bar code), multiple cells of different origin and history may be placed into the same experiment allowing multiplexed experiments to be performed.

Mutated versions of Cas12a that remove its non-specific ssDNA cleavage activity without affecting site-specific double-stranded DNA cutting activity. These mutant proteins, in which a short amino acid sequence is deleted or changed, provide improved genome editing tools that will avoid potential off-target editing due to random ssDNA nicking.

Clinical Prognostication Test In Uveal Melanoma

Uveal melanoma commonly known as ocular or choroidal melanoma, is a rare cancer of the eye. It is an intraocular malignancy that arises from melanocytes of the choroid, ciliary body, and iris of the eye. Ocular melanoma is diagnosed in approximately 2,000-2,500 adults annually in the United States. In both the U.S. and Europe, this equates to about 5 - 7.5 cases per million people per year and, for people over 50 years old, the incidence rate increases to around 21 per million per year. While the primary tumor is highly treatable, about half of the patients will develop metastasis —typically to the liver. Metastatic disease is universally fatal. While traditional staging methods such as tumor size and location, still play a role in assessing metastatic risk, they are rarely used to individualize patient management plans. Newer methods include chromosomal gene expression analysis, yet these methods have their technical limitations. Clearly, what is needed is a better, cheaper and reproducible prognostic test.

Simple Imaging Tool for Oral Cancer Detection and Monitoring

UCI researchers have developed a miniature, flexible intra-oral probe with a camera that allows early detection of oral cancer lesions in difficult-to-see, high risk areas of the mouth and throat. The tool allows for a low cost, non-invasive procedure that can be easily adopted in non-specialist medical settings.

The emergence of several cell based therapy candidates in the clinic is an encouraging sign for human diseases/disorders that currently have no effective small molecule or biologic based therapy. Stem cells – including adult and pluripotent subtypes – offer tremendous clinical promise for the treatment of a variety of degenerative diseases, as these cells have the capacity to self-renew indefinitely and to mature into functional cell types and thereby serve as a source of cell replacement therapies (CRTs) and pluripotent stem cells (hPSCs) are of increasing interest for the development of CRTs because of their capacity to differentiate into all cell types in an adult, for which adult tissue-specific stem cells may in some cases not even exist. One potential CRT enabled by hPSCs is oligodendrocyte progenitor cells (OPCs) for the treatment of spinal cord injury (SCI). Such hPSC-OPCs have recently advanced to a Phase II clinical trial and are even being considered for additional diseases in the central nervous system (CNS), such as multiple sclerosis (MS), or injury from radiation.   UC researchers have developed a microscale 3D culture screening and analysis methodology that is relevant to the production of several up and coming cell replacement therapy candidates for which derivation from a precursor cell type requires searching through a large in vitro design space of doses, durations, dynamics, and combinations of signaling cues over several weeks of culture, such as oligodendrocyte progenitor cells (OPCs) and midbrain dopaminergic neurons (mDA neurons) derived from human pluripotent stem cells.
