Serum Levels of Neurofilament Light Chain Distinguish FTLD

While searching for biomarkers to diagnose frontotemporal lobar degeneration (FTLD), researchers employed the ultrasensitive single molecule array (Simoa) DNA analysis technique to detect neurofilament light chain (NfL) in cerebrospinal fluid (CSF) and, less invasively, from blood samples. More...

Immune Processes Linked to Multiple Sclerosis Genetics

Multiple sclerosis (MS) is an autoimmune inflammatory degenerative disease of the central nervous system that often starts in young adulthood and affects 2.3 million individuals worldwide. While prior genetic studies have implicated the adaptive immune system in the disease, in particular T cells, much of the genetic architecture of MS has remained unknown. More...

Methylation Signature Identified for Brain Metastases of Lung Cancer

When lung cancer metastasizes to the brain, it means the primary lung cancer has created a secondary cancer in the brain. About 20% to 40% of adults with non-small cell lung cancer go on to develop brain metastases at some point during their illness. More...

PCR Kit Developed for Detection of Q-fever Pathogen

Coxiella burnetii is an obligate intracellular bacterium that causes Q fever in animals and humans. The infection results from inhalation of a spore-like small-cell variant, and from contact with the milk, urine, feces, vaginal mucus or semen of infected animals. More...
