Scientists unravel mystery of T cell signaling process vital to immune response

The immune system cells known as T cells play a central role in the body's ability to fight infections and cancer. For decades, however, details of the molecular signaling process that leads to T cell activation have remained a mystery.

Breast cancer cells undergo stiffening state prior to becoming malignant, study shows

A study published now on Nature Communications shows that breast cancer cells undergo a stiffening state prior to acquiring malignant features and becoming invasive.

Discovery of steroid hormone in fruit flies may shed new light on maternal hypothyroidism

University of Oregon researchers using Drosophila have identified a steroid hormone that triggers a vital transition in early brain development in which neural stem cells properly change gears to produce different kinds of neurons.

LMU scientists uncover molecular mechanism that links tumor hypoxia and metastasis

The low oxygen concentrations that prevail in many tumors enhance their propensity to metastasize to other tissues. Researchers at Ludwig-Maximilians-Universitaet in Munich led by Professor Heiko Hermeking have now uncovered the molecular mechanism that links the two phenomena.

UC researchers find stem cell vaccine to enhance immune responses against tumors in animal models

Researchers at the University of Cincinnati have found that a cancer stem cell vaccine, engineered to express a pro-inflammatory protein called interleukin-15 (IL-15) and its receptor (IL-15Ralpha), caused T cell production in animal models and enhanced immune responses against tumors.

Scientists study cell’s reaction to Salmonella by visualizing protein chains at near-molecular level

With drug resistance being on the rise worldwide, bacterial infections pose one of the greatest global threats to human health. By deciphering the host-pathogen interaction on a molecular level, researchers hope to pave the way for new therapies.

Testosterone protects males against developing asthma, research reveals

An international research team has revealed for the first time that testosterone protects males against developing asthma, helping to explain why females are two times more likely to develop asthma than males after puberty.

Study: Use of white blood cell boosting drugs found to be safe during chemo-radiotherapy of lung cancer

A late breaking subanalysis of the phase III CONVERT trial presented at the European Lung Cancer Conference shows that white blood cell boosting drugs are safe during concurrent chemo-radiotherapy of small cell lung cancer (SCLC).

TSRI scientists uncover regulatory machinery underlying the function of cancer protein

Despite intense research, there's been much confusion regarding the exact role of a protein in a critical cancer-linked pathway. On one hand, the protein is described as a cell proliferation inhibitor, on the other, a cell proliferation activator, a duality that has caused a great deal of scientific head scratching.

Lethal DNA re-replication may be used to attack cancer cells

DNA over-replication is a phenomenon that can have devastating consequences for proliferating cells. When parts of the genome are duplicated more than once, cells suffer from 'genomic instability' (alterations to the structure, composition and/or number of chromosomes), and this process gives rise to aberrant cells as those detected in many carcinomas.

Impaired effects of insulin can increase cancer risk, shows study

Over the decades, scientists have repeatedly shown that patients with increased levels of the hormone insulin in their blood can experience increased risks of cancer. Surprisingly, however, Joslin Diabetes Center researchers now have discovered that impaired effects of insulin also can boost these risks.

TACC's supercomputers assist in discovery of new, better chemotherapy drugs

Surgery and radiation remove, kill, or damage cancer cells in a certain area. But chemotherapy -- which uses medicines or drugs to treat cancer -- can work throughout the whole body, killing cancer cells that have spread far from the original tumor.

China creates new kinase-based whole-cell screening library for high-throughput drug assay

After five years of hard work, China has completed the world's largest kinase-based whole-cell screening library for high-throughput drug assay.

Growing mouse tooth provides new understanding of tissue renewal processes

Researchers hope to one day use stem cells to heal burns, patch damaged heart tissue, even grow kidneys and other transplantable organs from scratch.

Scientists announce ‘outstanding’ results of new blood cancer study

Scientists have described new results of a blood cancer study as 'outstanding' in tackling previously untreatable forms of chronic lymphocytic leukemia.

Researchers take important step toward using transplanted fetal cells to treat liver failure

In a new study, researchers demonstrate successful transplantation of fetal rat liver cells to an injured adult rat liver. The work is an important step toward using transplanted cells to treat liver failure, which currently requires an organ transplant.

Drinking more than three cups of Italian-style coffee each day lowers prostate cancer risk

Add another typical component of the Italian way of life to the long list of foods characterizing one of the most healthy populations in the world. This time it's coffee, prepared the Italian way.

Scientists develop new drug that combats two ‘priority pathogens’

Scientists at St. Boniface Hospital Albrechtsen Research Centre and the University of Manitoba have developed a drug that combats 2 of the top 10 "priority pathogens" recently defined by the World Health Organization as antiobiotic-resistant bacteria requiring new interventions.

Researchers report new evidence that defective HIV proviruses distract immune system

Researchers at Johns Hopkins and George Washington universities report new evidence that proteins created by defective forms of HIV long previously believed to be harmless actually interact with our immune systems and are actively monitored by a specific type of immune cell, called cytotoxic T cells.

Strawberry extract can inhibit spread of breast cancer cells, mice study shows

A study by European and Latin American researchers has shown that strawberry extract can inhibit the spread of laboratory-grown breast cancer cells, even when they are inoculated in female mice to induce tumours.
