Fluorescence microscopy is an imaging technique used to examine cells and their internal components. Specific cellular components can be labeled with fluorophores.

NPL scientists mimick the ways viruses infect human cells and deliver genetic material

Scientists at the National Physical Laboratory (NPL) have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy - a therapeutic strategy to correct defective genes such as those that cause cancer.

Researchers identify new mechanism underlying MS

Multiple sclerosis is a disabling autoimmune disease in which nerve fibers are attacked by the patient's own immune system. Researchers at Ludwig-Maximilians-Universitaet in Munich have identified a new mechanism that contributes to nerve fiber damage - and shown that this damage can be reversed.

Cell receptor recycling mechanism discovery opens up new class of therapeutic targets

Prof. Manojkumar Puthenveedu of Carnegie Mellon University studies the mechanisms by which membrane trafficking controls and co-ordinates the complex signalling pathways in the brain. Despite the fact that almost all diseases can be traced to a defect in how cells respond to signals, little is known about how signalling pathways are maintained in normal cells and the changes that occur in abnormal conditions.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

Healthy eggs require tremendous amount of zinc to reach maturity for fertilization: Research

Scientists as well as fertility doctors have long tried to figure out what makes a good egg that will produce a healthy embryo. It's a particularly critical question for fertility doctors deciding which eggs isolated from a woman will produce the best embryos and, ultimately, babies.New research reveals healthy eggs need a tremendous amount of zinc to reach maturity and be ready for fertilization,a finding that may ultimately help physicians assess the best eggs for fertility treatment, according to a study from Northwestern University.

Histone H1 phosphorylation involved in control of ribosomal RNA gene transcription

A protein that helps pack DNA into the cell nucleus has an important role in regulating gene activity, scientists report. The researchers found that the protein, histone H1, also takes part in the formation of ribosomes, the cellular workbenches on which all proteins are made.
