Simple Skin Biopsy Test Detects Parkinson’s and Related Neurodegenerative Diseases

Parkinson’s disease and a group of related neurodegenerative disorders known as synucleinopathies impact millions globally. These conditions, including Parkinson’s disease (PD), dementia with Lewy bodies (DLB), multiple system atrophy (MSA), and pure autonomic failure (PAF), are progressive neurodegenerative diseases that, despite having some similar symptoms like tremors and cognitive issues, vary in their outcomes and do not benefit from identical treatments. A common feature among them is the accumulation of an abnormal protein in nerve fibers within the skin, known as phosphorylated α-synuclein (P-SYN). Now, neurologists have developed a simple skin biopsy test that can detect this abnormal form of alpha-synuclein with high positivity rates in individuals with such disorders. In the study, neurologists at Beth Israel Deaconess Medical Center (BIDMC, Boston, MA, USA) enrolled 428 people, ages 40-99 years who were either diagnosed with one of the synucleinopathies based on clinical evaluations confirmed by specialists or were healthy volunteers ...

New Genomic Method Helps Diagnose Patients with Unexplained Kidney Disease

Kidney failure poses a significant threat to life if not adequately treated, yet precise diagnosis often eludes patients, leaving them uncertain about the best treatment approach. Now, a groundbreaking advancement by scientists has led to the discovery of a new technique for examining genomic data that could offer an accurate diagnosis for those suffering from unexplained kidney failure. Researchers from Newcastle University (Newcastle upon Tyne, UK) used data from the Genomics England 100,000 Genomes Project to establish a diagnosis for patients facing unexplained kidney failure. They discovered that certain segments of these patients’ genomes were absent, as a result of which their conditions went undiagnosed with standard genetic analysis techniques. The researchers have now identified this missing gene and found the mutations within it, allowing them to classify this as NPHP1-related -related kidney failure. For their study, the team reviewed the genetic sequencing data of 959 individuals with advanced kidney ...

Fluid Biomarker Test Detects Neurodegenerative Diseases Before Symptoms Appear

Amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig’s disease) and frontotemporal dementia (FTD) are two progressively neurodegenerative conditions that damage essential nerve cells. ALS compromises nerve cells in the brain and spinal cord, leading to movement impairment, while FTD damages brain areas responsible for personality, behavior, and language. Studies indicate that in ALS or FTD patients, TAR DNA-binding protein 43 (TDP-43) malfunctions. This disruption prevents the correct splicing of ribonucleic acid (RNA), essential for generating proteins necessary for nerve growth and function. Instead, RNA strands become riddled with erroneous code sequences, known as “cryptic exons,” which are linked to an elevated risk of developing ALS and FTD. The timing of this anomaly in the disease progression of ALS and FTD was previously unknown. Now, researchers from Johns Hopkins Medicine (Baltimore, MD, USA) have developed a method for identifying a specific protein, hepatoma-derived growth factor-like 2 [HDGFL2], linked to TDP-43 ...

Coin-Sized Device Rapidly Isolates Blood Plasma for Quicker and More Precise Clinical Diagnoses

Identifying biomarkers for various cancers and diseases often relies on cell-free DNA, RNA, and extracellular vesicles. Traditionally, separating blood plasma to detect these markers requires centrifugation, spinning blood to isolate cells from plasma. Yet, even after multiple centrifugation cycles, some cells and platelets remain in the blood plasma, potentially releasing unwanted biological materials that can affect diagnostic accuracy. Researchers have now developed a compact, coin-sized chip capable of extracting blood plasma directly from a sample within 30 minutes, resulting in a more convenient and user-friendly option than the currently laborious centrifugation method. The chip named ExoArc, developed by scientists at Nanyang Technological University (NTU, Singapore), offers a one-step solution to achieve over 99.9% purity by efficiently removing blood cells and platelets. This advance promises quicker and more reliable clinical analysis of critical biomarkers. To demonstrate its utility, the team developed a portable prototype device (measuring 30cm x 20cm x 30cm) ...

Precision Medicine Startup Mirador Unveils $400M for R&D of New I&I Drugs

Mirador Therapeutics applies machine learning to human data to discover new immunology and inflammation drugs. The startup’s management includes several from the executive team of Prometheus Biosciences, an immunology biotech bought by Merck last year. By FRANK VINLUAN Nearly a year ago, Merck struck a $10.8 billion deal to acquire Prometheus Biosciences, a clinical-stage company whose technology platform analyzed genetics and biology data to discover new drugs. The executive who led Prometheus to that buyout is now back with a new immunology startup supported by $400 million. Mirador Therapeutics launched Thursday, aiming to take the precision medicine approaches that have led to advances in cancer drugs and apply them to the research of new therapies for immunology and inflammation. It’s a similar strategy to the one taken by Prometheus under the helm of Mark McKenna, now the CEO of San Diego-based Mirador. There’s a plethora of immunology drugs on the ...

Groundbreaking pTau217 Blood Test as Accurate as Brain Imaging or CSF Testing in Diagnosing Alzheimer’s

Alzheimer’s disease (AD) is a neurodegenerative condition that causes the brain to deteriorate over time, marked by the buildup of certain harmful proteins that eventually lead to a decline in brain function and cell death. These changes can happen long before any symptoms show up. Scientists have found certain proteins in the cerebrospinal fluid that are good indicators of AD. One of the most promising markers for early and more precise detection of AD in the blood is phosphorylated tau at position 217 (pTau217). It’s seen as a game-changer for diagnosing AD sooner, categorizing patients for research studies, and improving how patients are cared for and treated. Now, an innovative and novel blood test can be used in the screening, diagnosis, and monitoring of AD based on the circulating level of this promising biomarker pTau217. ALZpath Dx (Carlsbad, CA, USA) has developed a robust and scalable plasma-based ultra-sensitive assay, branded ...

AI Predicts Cancer Spreading To Brain from Lung Biopsy Images

Lung cancer is the leading cause of cancer-related deaths globally, with non-small cell lung cancers making up the majority of cases, which are often linked to smoking. When detected early, these cancers are usually confined to the lung, making surgery the preferred initial treatment. However, about 30% of these early-stage patients see their cancer advance to more critical areas, like the lymph nodes and organs, frequently affecting the brain first. This progression necessitates additional treatments such as chemotherapy, targeted drugs, radiation, or immunotherapy. Unfortunately, despite 70% of patients not developing brain metastasis, doctors have lacked the means to predict whose cancer will progress and often opt for aggressive treatments as a precautionary measure. Now, a new study offers hope in improving the approach to treating early-stage lung cancer by achieving the correct balance between proactive intervention and cautious monitoring. In the study, scientists at Washington University School of Medicine in ...

Cells Harvested From Urine to Enable Earlier Kidney Disease Detection

Detecting kidney disease late can lead to severe and even life-threatening issues. Now, new research has found that the genes expressed in human cells harvested from urine closely match those in the kidney, suggesting that these cells could offer a non-invasive approach to better understanding kidney health. This discovery could allow the diagnosis of kidney problems without doing biopsies, making it possible to detect kidney disease earlier and more easily. A team of scientists led by the University of Manchester (Manchester, UK) used a method called transcriptomics to measure the levels of about 20,000 genes in each cellular sediment sample of urine. Transcriptomics helps scientists see which genes are active or inactive, providing insights into how cells adapt to changes in their environment. This molecular-level understanding can lead to more accurate diagnoses and better patient outcomes. The team also had access to the world’s largest collection of human kidney samples ...
