Signature for Beta-Cell Autoimmunity Predicts Type 1 Diabetes

The appearance of Type 1 diabetes (T1D)-associated autoantibodies is the first and only measurable parameter to predict progression toward T1D in genetically susceptible individuals. More...

Mutations Linked to Familial Pancreatic Cancer Identified

Pancreatic ductal adenocarcinoma is an aggressive cancer with limited treatment options. Approximately 10% of cases exhibit familial predisposition, but causative genes are not known in most families. More...

Potential Biomarkers Found in Glioblastoma Small Extracellular Vesicles

Tumor small extracellular vesicles (sEVs), which are accessible in biofluids such as blood, contain valuable biomarkers for glioblastoma (GBM) patient diagnosis and follow-up. More...

Image: Follicular helper T-cells (cells with green surface markers) interact closely with B-cells (cells with orange surface markers) to facilitate the proliferation of B- cells and the production of high affinity antibodies. The interaction site is shown in yellow, DNA in blue (Photo courtesy of Joyce Hu, La Jolla Institute for Allergy and Immunology).

Specialized White Blood Cells Prove Biomarkers for Diabetes Progression

Researchers have found that a specialized class of circulating white blood cells (CXCR5−PD-1hi Tph cells) are associated with progression for autoantibody positivity to clinical type I diabetes and have the potential to serve as biomarkers to monitor progression of this disease. More...

Study Supports Body Area Sensory Networks for Diagnostic Monitoring

The first steps have been taken on the path leading to development of a body area sensor network, which is a collection of networked sensors that can be used to remotely monitor human physiological signals. More...

Image: A pair of genes that influence risk for Alzheimer’s disease, MS4A4A and TREM2, affect immune cells in the brain. They influence Alzheimer’s risk by altering levels of TREM2, a protein (shown stained in red) that is believed to help microglia cells clear excessive amounts of the Alzheimer’s proteins amyloid and tau from the brain. The MS4A4A protein is shown stained in green (Photo courtesy of Fabia Filipello and Dennis Oakley, Washington University School of Medicine).

Brain Biomarkers Predict Alzheimer's Disease Risk and Progression

A cluster of genes has been identified that modulates the activity of TREM2 (Triggering receptor expressed on myeloid cells 2), a protein biomarker for risk and progression of Alzheimer’s disease (AD). More...

Congenital Cytomegalovirus Infection Diagnosed Via Dried Blood Spots

Cytomegalovirus is the leading cause of congenital infection (cCMV) affecting up to 0.8% of newborns in high-income countries and is the most common cause of non-genetic deafness in childhood. A wide range of diseases diagnosed either at birth or in childhood, has been correlated to cCMV infection. More...
