July 17, 2018 Without T cells, we could not survive. They are a key component of our immune system and have highly sensitive receptors on their surface that can detect pathogens. The exact way that these receptors are distributed over the surface of the T cells is still not completely understood, but the analyses by […]Continue Reading ...
July 20, 2018 University of North Carolina Lineberger Comprehensive Cancer Center scientists have uncovered a potential therapeutic target for kidney cancers that have a common genetic change. Scientists have known this genetic change can lead to an overabundance of blood vessels, which help feed nutrients to the tumors. Their latest finding shows a potential new […]Continue Reading ...
July 20, 2018 An international group of researchers have raised the viability of mice that were cloned using a method called somatic cell nuclear transfer, by stimulating two epigenetic factors, and by doing this have shown that creating cloned animals more efficiently will require further work in the area of epigenetics. They have also uncovered […]Continue Reading ...
One of the most important cell types for controlling certain viral infections are natural killer (NK) cells. As part of the innate and rapid immune response, NK-cell recruitment and activation was thought to be a straightforward process. New research shows that NK-cell recruitment and activation requires a rather carefully choreographed interaction of three cell types […]Continue Reading ...
FRIDAY, July 13, 2018 — Neither glargine followed by metformin nor metformin alone halts the progressive deterioration of β-cell function in youth with impaired glucose tolerance (IGT) or recently-diagnosed type 2 diabetes, according to a study published online June 25 in Diabetes Care. On behalf of the RISE Consortium in Rockville, Md., Sharon L. Edelstein […]Continue Reading ...
July 12, 2018 When a cell divides, its constituents are usually evenly distributed among the daughter cells. UZH researchers have now identified an enzyme that guarantees that cell constituents that are concentrated in organelles without a membrane are properly distributed. Their discovery opens up new opportunities for the treatment of cancer, neurodegenerative diseases, aging processes […]Continue Reading ...
July 12, 2018 A new study from a team of researchers at Children’s Hospital of Philadelphia (CHOP) and the University of Pennsylvania School of Nursing (Penn Nursing) found that in the previous three months, about half of parents talked on a cell phone while driving when their children between the ages of 4 and 10 […]Continue Reading ...
Dying cells generally have two options: go quietly, or go out with a bang. The latter, while more conspicuous, is also mechanistically more mysterious. Now, scientists at the Stanford University School of Medicine have pinpointed what they believe is the molecular “code” that unleashes this more violent variety of cell death. This particular version of […]Continue Reading ...
July 20, 2018 Dr Maddy Parsons, a Group Leader in the Randall Division of Cell & Molecular Biophysics, has been awarded the Royal Microscopical Society Life Science Medal for her outstanding scientific contribution to applying microscopy in the field of cell biology. The award follows a nomination by Professor Anne Ridley, Head, Cell Motility and […]Continue Reading ...
‘Timer’ protein fluorescence across time. Credit: Imperial College London Scientists are unveiling how our immune system works – and malfunctions – thanks to an innovative technology that tracks immune cells. The technology has already been used to look at immune cells involved in a mouse model of multiple sclerosis, and could provide valuable insights into […]Continue Reading ...
As an increasing number of infectious bacteria develop resistance to antibiotics, the hunt for new strategies to combat them becomes ever more urgent. One approach is to learn more about bacteria themselves, and, as a new study in Nature suggests, these tiny, abundant organisms harbor some secrets that we still haven’t discovered. The new research, […]Continue Reading ...
It’s a lot to ask of a run-of-the-mill blood draw, but Curtis and her group are devising a search tactic that goes beyond identifying rare mutations in DNA. She’s looking at epigenomic footprints, types of markers typically embedded in DNA. While these markers are often found enclosed in the cell, Curtis takes advantage of cell-free […]Continue Reading ...
July 13, 2018 Findings from an animal study suggest that a non-invasive imaging technique could, with further development, become a useful tool to assess immune system recovery in people receiving treatment for HIV infection. Researchers used single-photon emission computed tomography (SPECT) and a CD4-specific imaging probe to assess immune system changes throughout the bodies of […]Continue Reading ...
July 13, 2018 Engineering cellular biology, minus the actual cell, is a growing area of interest in biotechnology and synthetic biology. It’s known as cell-free protein synthesis, or CFPS, and it has potential to provide sustainable ways to make chemicals, medicines and biomaterials. Unfortunately, a long-standing gap in cell-free systems is the ability to manufacture […]Continue Reading ...
While scientists have made enormous headway in the fight against cancer, scientific understanding of tumors at the level of their most fundamental unit – the cell – has been relatively limited. With the advent of new technologies such as single-cell sequencing, big data analytics and advanced bioinformatics pipelines, it is now possible to examine individual […]Continue Reading ...
