Naturally-occurring molecule can cause immune cells to go into hyperactive state

Researchers at Boston Children's Hospital report that a fatty chemical naturally found in damaged tissues can induce an unexpected kind of immune response, causing immune cells to go into a "hyperactive" state that is highly effective at rallying infection-fighting T-cells. The findings, published online by Science on April 21, could enhance vaccines and make them much more effective.

Scientists develop CRISPRainbow to study genome structure in real time

CRISPRainbow, a new technology using CRISPR/Cas9 developed by scientists at UMass Medical School, allows researchers to tag and track up to seven different genomic locations in live cells. This labeling system, details of which were published in Nature Biotechnology, will be an invaluable tool for studying the structure of the genome in real time.

Hippo signaling pathway controls phases of quiescence in fruit fly central nervous system

Neural stem cells are responsible for the formation of differentiated daughter cells in the developing brain. If no new cells are needed, the stem cells may enter a resting phase called quiescence. Biologists at Johannes Gutenberg University Mainz have now discovered that the phases of quiescence in the Drosophila fruit fly central nervous system are controlled by the Hippo signaling pathway. Drosophila serves as a model organism that helps geneticists to decode the molecular fundamentals of cellular biology and unravel mechanisms that are conserved in human beings and other vertebrates.

SI-2 molecule can inhibit tumor growth in breast cancer mouse model

Cancer cells communicate with their environment through cell molecules that pass on signals to the inside of the cell. The signals help cancer cells multiply and migrate, spreading the disease.

TNF-alpha protein involved in autoimmune diseases may also promote tissue healing

As its name suggests, inflammatory bowel disease, which afflicts more than 1.6 million Americans, involves chronic inflammation of all or some of the digestive tract. An autoimmune disease known to have a strong genetic component, its symptoms are abdominal cramps, bloody diarrhea, and fever and, sometimes, weight loss. IBD, which is a group of inflammatory conditions, includes Crohn's disease and ulcerative colitis.

Caltech researchers map out pathways of neurons responsible for Parkinson's motor impairments

Because billions of neurons are packed into our brain, the neuronal circuits that are responsible for controlling our behaviors are by necessity highly intermingled. This tangled web makes it complicated for scientists to determine exactly which circuits do what. Now, using two laboratory techniques pioneered in part at Caltech, Caltech researchers have mapped out the pathways of a set of neurons responsible for the kinds of motor impairments--such as difficulty walking--found in patients with Parkinson's disease.

Scientists find interaction between amyloid and tau proteins that cause brain damage linked with AD

For years, neuroscientists have puzzled over how two abnormal proteins, called amyloid and tau, accumulate in the brain and damage it to cause Alzheimer's disease (AD). Which one is the driving force behind dementia? The answer: both of them, according to a new study by researchers at the Douglas Mental Health University Institute.

Novel gene therapy can improve symptoms of Bubble Boy disease in young adults

Adolescents and young adults with a severe inherited immunodeficiency disorder improved following treatment with novel gene therapy developed at St. Jude Children's Research Hospital and at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. The results of this study appear today in the journal Science Translational Medicine.

Scientists aim to identify marker that could indicate aggressive basal cell skin cancer

Most basal cell skin cancers are easily removed -- those on the arm, leg or back. But when the cancer is on the eyelid or when it starts to invade surrounding tissue, it's no longer straightforward.

Using Proteomics to Understand Alzheimer’s: An Interview with Dr Renã Robinson

In our bioanalytical mass spectrometry lab we use proteomics techniques to try to understand more about Alzheimer's disease. The primary thrust of our research is that we're interested in understanding the changes that take place outside of the brain and how those correlate with what's taking place inside the brain

LAP defects may lead to lupus-like autoimmune disorder

A casual observation about size differences in mice has led to the discovery that defects in a process for digesting dead cells called LC3-associated phagocytosis (LAP) may lead to a lupus-like autoimmune disorder. St. Jude Children's Research Hospital scientists led the research, which appears as an advance online publication today in the scientific journal Nature.

Scientists discover CD2AP protein that plays key role in nervous system

University of Louisville researchers have discovered that a protein previously known for its role in kidney function also plays a significant role in the nervous system. In an article featured in the April 13 issue of the Journal of Neuroscience, they show that the adaptor protein CD2AP is a key player in a type of neural growth known as collateral sprouting.

KEYNOTE-001 findings add support to pembrolizumab for advanced melanoma

A third of patients with advanced or metastatic melanoma will achieve an objective response to treatment with the programmed cell death protein inhibitor pembrolizumab, suggest KEYNOTE-001 findings, regardless of whether they have previously been treated with ipilimumab.

Proteins can be used as targets to deliver drugs into stressed cancer cells

Targeted missiles that can enter cancer cells and deliver lethal cell toxins without harming surrounding healthy tissue. This has been a long-standing vision in cancer research, but it has proved difficult to accomplish. A research group at Lund University in Sweden has now taken some crucial steps in this direction.

New study suggests re-evaluation of long-held method to predict effectiveness of seasonal influenza vaccine

The long-held approach to predicting seasonal influenza vaccine effectiveness may need to be revisited, new research suggests. Currently, seasonal flu vaccines are designed to induce high levels of protective antibodies against hemagglutinin (HA), a protein found on the surface of the influenza virus that enables the virus to enter a human cell and initiate infection.

Study shows beneficial effect of hNSC transplantation for TBI

Traumatic brain injury (TBI) is a major cause of mortality and morbidity, often causing lifelong disability for those who survive. Treatment is limited to supportive care, but stem cell therapy has received recent attention as a way to promote recovery for injuries to the central nervous system (CNS). In this study, researchers transplanted human neural stem cells (hNSCs) into the brains of mice modeled with TBI to investigate whether the hosts' immune systems and the stem cells acting in concert would enhance repair.

Immunotherapy drug pembrolizumab shrinks tumors in patients with Merkel cell carcinoma

In a clinical trial of the immunotherapy drug pembrolizumab, half of 25 patients with a rare type of virus-linked skin cancer called Merkel cell carcinoma experienced substantial tumor shrinkage lasting nearly three times as long, on average, than with conventional chemotherapy.
