Is a Low-Cost Blood Test for Alzheimers on the Horizon?

BioSpace | August 02, 2019

One of the many problems facing researchers working to develop treatments for Alzheimers disease is the lack of good diagnostic tests. Although there are some biomarkers, such as ApoE4, that show a connection to the disease, they are not reliable predictors or diagnoses. Even physician diagnosis is suspect some studies have shown that community doctors only diagnose Alzheimers accurately 50 to 60% of the time, which is roughly equivalent to a coin-toss. Researchers at Washington University in St. Louis have developed a high-precision assay that can accurately identify amyloid in the brain using immunoprecipitation and liquid chromatography-mass spectrometry. One of the problems that immediately comes to mind about this test is the current unanswered questions about amyloid in the brain and its role in Alzheimer’s disease. For the last several decades, researchers have focused on clearing or preventing the accumulation of amyloid, a type of protein, from accumulating in the brain, because it was thought that the disease was caused by clumping of this protein. Unfortunately, most researchers have concluded that this is ineffective. Current thinking is that amyloid accumulation definitely plays a role in the disease, but in and of itself is not the cause of the disease. It is, however, a significant risk factor, and a blood test that can identify amyloid deposits before brain scans do would be beneficial for physicians diagnosing the disease and for biopharma companies conducting clinical trials.

Quantum-Si and Biovista Join Hands to Provide AI-driven Deep Proteomics Insights

Quantum-Si | January 10, 2023

The leading Protein Sequencing Company™, Quantum-Si, recently announced that it signed a partnership and license agreement with Biovista to offer customers more significant proteomic insights beyond their protein sequence output. Biovista utilizes artificial intelligence in multiple formats to analyze enormous data repositories and visualize non-obvious networks and connections between proteins, diseases, and drug mechanisms of action. The partnership enhances Quantium-Si's services significantly by making proteomic-to-drug workflows more efficient for researchers. Biovista's VIZIT™ exploration tool will be incorporated into Quantum-Si's cloud-based suite of analytic tools, allowing researchers to visualize the connections between the protein sequences identified during their experiment to diseases, other proteins, and post-translational modifications. Thus, researchers can identify potential disease-specific mechanisms and biomarkers more efficiently and effectively. "Quantum-Si's protein sequencing technology in concert with Biovista's database and visualization technology can aid in the discovery of new proteins for future therapeutic targets associated with disease," said Jeff Hawkins, CEO of Quantum-Si. He further stated, "The potential can also extend to discovering new biomarkers for clinical research and diagnostics." (Source- Business Wire) "Quantum-Si is leading the next generation of real-world meaningful sequencing," said Dr. Aris Persidis, Biovista's Co-Founder and President. "We are excited to see deep sequencing and insight generation now available in one integrated platform," he concluded. (Source- Business Wire) About Quantum-Si Quantum-Si, The Protein Sequencing CompanyTM, is dedicated to revolutionizing the rapidly expanding field of proteomics. It provides the first-of-its-kind, end-to-end, universal single-molecule detection solutions, allowing to build, experiment, and discover on its platform regardless of their existing products. In addition, its proprietary Time Domain Sequencing technology eliminates the reliance on color as an identification method, a barrier for any application outside of genomics, where only four colors are required.

Lineage Enters Exclusive Option and License Agreement with Eterna

Lineage Cell Therapeutics, Inc. | February 23, 2023

On February 22, 2023, Lineage Cell Therapeutics, Inc., a clinical-stage biotechnology firm focused on the development of allogeneic cell therapies to restore and replace specific cell types of the human body, announced that it has entered into an exclusive option and license agreement with Eterna Therapeutics Inc. (Eterna) for the development of innovative beta 2 microglobulin (B2M)-deficient induced pluripotent stem cell (iPSC) lines that Lineage will assess for the creation of unique, differentiated cell transplant therapies. These new cell lines to be developed by Eterna are expected to help Lineage generate more product candidates for the treatment of central nervous system (CNS) conditions and other neurology indications. Eterna holds the exclusive license for the crucial intellectual property associated with this partnership, which it obtained from its discovery partner Factor Bioscience. Following the agreement, Eterna intends to perform specific gene-editing activities and furnish materials to Lineage for assessment. In addition, the agreement grants Lineage the option to obtain an exclusive license to use and sublicense the new gene-edited cell lines for clinical, preclinical, and commercial purposes in the field of CNS diseases. A distinctive feature of the starting cell line is the targeted elimination of the B2M gene, which is aimed at minimizing the immunogenicity of product candidates generated from the cell lines by inhibiting rejection by CD8+ T cells. Lineage anticipates that this attribute will enhance the overall usefulness of the edited cell lines, including non-immune privileged or non-human leukocyte antigen (HLA) matched indications. Other proposed gene modifications may additionally differentiate the cell line from those currently utilized by competitors. No details of the financial agreement were disclosed. About Lineage Cell Therapeutics, Inc. Founded in 1990, Lineage Cell Therapeutics is a clinical-stage biotechnology company focused on developing novel cell therapies to address unmet medical needs. The company's programs are based on its proprietary cell-based therapy platform and related development and manufacturing capabilities. By using this platform, it specializes in the development and manufacture of specialized, terminally-differentiated human cells from its progenitor and pluripotent cell starting materials. These differentiated cells are intended to either support or replace cells that are dysfunctional or absent due to degenerative disease or traumatic injury and can also be administered to help the body mount an effective immune response to cancer.
