Flow Cytometry News and Research

RSS

Flow cytometry is a technique for counting and examining microscopic particles suspended in a stream of fluid. It allows simultaneous multiparametric analysis of the physical and/or chemical characteristics of single cells flowing through an optical and/or electronic detection apparatus.

Scientists take a close look at early events in immune response

A Sandia National Laboratories research team led by Anup Singh is taking a new approach to studying how immune cells respond to pathogens in the first few minutes and hours of exposure.

Importance of T cells in the prevention of autoimmune diseases

Centenary scientist Associate Professor Barbara Fazekas de St. Groth, a leader in inflammatory bowel disease research, has demonstrated for the first time the important role of T cells in the prevention of autoimmune diseases in humans.

Flow technique - a quick and simple technique to characterize breast cancer cells

A quick and simple technique to characterize breast cancer cells may expedite and improve treatment decisions, researchers from the University of Illinois at Chicago report in the journal of Experimental and Molecular Pathology.

Discovery of the molecular mechanism that inhibits HCV replication in vitro

Since its discovery several decades ago, the insidious human pathogen has stymied the quest for anti-viral therapies by refusing to reproduce in test tubes for more than a few hours or days, denying scientists an efficient virus production and infection system for experimental research.

Study shows that high-fat diets correlate to a chronic inflammatory state in the liver,

Mice that were fed diets high in fat and sugar developed immune system abnormalities in their livers, including reduced numbers of natural killer T (NKT) cells. These diet-related changes may contribute to obesity-related liver disease, according to a new study.

Counting number of endothelial cells in blood may predict cancer treatment's effectiveness

Counting the amount of a type of normal cell circulating in the blood of people with cancer could predict whether a tumor progresses or responds to therapy, a new study led by the University of Michigan Comprehensive Cancer Center has found. The finding could give doctors an early indication of whether a treatment will be successful, sparing patients months of an ineffective therapy.

How does the body keep the number of neutrophils produced constant in the blood?

Every day, the human body manufactures and destroys about 100 billion neutrophils- the most common type of white blood cell and one of the most highly-produced cells. Neutrophils live about eight hours, are bacteria-eaters and are a key component of the immune system. Without them, the body can be subject to life-threatening infection.

Discovery that sheds new light upon the growth and development of human natural killer (NK) cells

Scientists here have made a major discovery that sheds new light upon the growth and development of human natural killer (NK) cells, powerful but somewhat mysterious components of the body’s immune system that are the first line of defense against cancer and infectious diseases.

Genomic DNA provides clues to new advances in cancer diagnostics

Researchers at the University of Illinois at Chicago have identified a method of assessing the malignant potential of cells based on the sensitivity of cellular DNA to enzyme digestion.

Researchers attempt to quantify processes underlying cell heterogeneity

Combining the latest methods in gene splicing and computer modeling, Rice University researchers are trying to develop a predictive framework for one of the most basic and complex biological phenomena — cellular heterogeneity, or the ability of genetic clones to act and behave differently when exposed to the same set of environmental stimuli.

Researchers identify biomarkers that could lead to more accurate diagnosis of systemic lupus erythematosus

University of Pittsburgh researchers have identified biomarkers that could result in earlier and more accurate diagnosis of systemic lupus erythematosus (SLE), a devastating disease that affects as many as 1.5 million Americans, and occurs 10 to 15 times more frequently in women.

Discovery may help to define the limits for life on Earth, as well as elsewhere in the universe

The discovery of millions of micro-microbes surviving in a 120,000-year-old ice sample taken from 3,000 meters below the surface of the Greenland glacier was announced by Penn State scientists today (May 26) at the General Meeting of the American Society for Microbiology in New Orleans, La. The discovery may help to define the limits for life on Earth, as well as elsewhere in the universe, such as on cold planets like Mars.

System Biosciences launches siRNA expression libraries to target 8,500 human genes

The siRNA libraries contain 7,500 and 43,800 siRNA template sequences that target 1,500 and 8,500 well-characterized human genes, respectively.

New Cell Sorter Helps Understand Deadly Diseases

Researchers at NC State’s College of Veterinary Medicine have a new state-of-the-art tool, a high-speed cell sorter, that should quicken the pace of their research. The machine sorts or collates cells into groups, allowing scientists to look only at the cells they are working on.
