Novel microcopy methods used to study tiny traction forces during T-cell activation

Highly complicated processes constantly take place in our body to keep pathogens in check: The T-cells of our immune system are busy searching for antigens - suspicious molecules that fit exactly into certain receptors of the T-cells like a key into a lock.

New understanding of physical properties of chromatin may show how genome is encoded and decoded

University of Alberta researchers have found an answer to a fundamental question in genomic biology that has eluded scientists since the discovery of DNA: Within the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid?

A protein plays key role in the spread of stress signals among liver cells

A key protein in the communication channels between cells can allow a stress response in one liver cell to spread to neighboring liver cells in mice, causing otherwise healthy cells to become dysfunctional, according to new research co-led by Harvard T.H. Chan School of Public Health and Sheba Medical Center in Israel.

New microscope could allow surgeons to inspect tumor margins within minutes

When surgeons remove cancer, one of the first questions is, "Did they get it all?" Researchers from Rice University and the University of Texas MD Anderson Cancer Center have created a new microscope that can quickly and inexpensively image large tissue sections, potentially during surgery, to find the answer.

Cell atlas helps better understand the biology of tropical disease parasite

The first cell atlas of an important life stage of Schistosoma mansoni, a parasitic worm that poses a risk to hundreds of millions of people each year, has been developed by researchers at the Wellcome Sanger Institute and their collaborators.

Pig stem cells offer a new way to grow human organs for transplantation

In a new paper published in Stem Cell Reports, Bhanu Telugu and co-inventor Chi-Hun Park of the University of Maryland (UMD) Department of Animal and Avian Sciences show for the first time that newly established stem cells from pigs, when injected into embryos, contributed to the development of only the organ of interest (the embryonic gut and liver), laying the groundwork for stem cell therapeutics and organ transplantation.

Discovery of protein function could be important for future chemotherapy treatment

Chemotherapy attacks all cells in our body and not just cancer cells, which is why patients undergoing the treatment often experience side effects such as physical weakness, hair loss and nausea.

Research suggests a novel mechanism for modulating emotional behavior

Research led by Si-Qiong June Liu, MD, PhD, Professor of Cell Biology and Anatomy at LSU Health New Orleans School of Medicine, discovered a surprising reciprocal interaction between chemicals in the brain resulting in accelerated loss of molecules that regulate brain cell communication.

Researchers discover cells responsible for resistance to T-ALL treatment

T-cell acute lymphoblastic leukemia (T-ALL) is a cancer of the blood that affects mainly children, but also less frequently adults. In adults, although the response to treatment might be initially positive, relapses are common and have a poor prognosis.

Researchers study the mechanisms of skin aging

The ageing process is most apparent on the skin. In the newly opened "SKINMAGINE" (Multimodal Imaging of Aging and Senescence of the Skin) Christian Doppler Laboratory, dermatologists from MedUni Vienna have joined forces with biotechnologists from the University of Natural Resources and Applied Life Sciences Vienna and chemists from Vienna University of Technology, as well as the company Chanel, to study the interaction of metabolism, cellular communication and cellular quality control in skin ageing accelerated by environmental stress.
