Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear. Now, a team of researchers at the La Jolla Institute for Allergy and Immunology has identified a pair of master regulators that control the fate of TFH cells.

More time spent standing rather than sitting could improve your blood sugar, fats in the blood and cholesterol levels, according to a new study published today (Friday) in the European Heart Journal. The study also shows that replacing time spent sitting with time walking could have additional benefits for your waistline and body mass index (BMI).

New research by scientists at the University of York has given tea and coffee drinkers new information about why their favourite drinks taste as they do.
The study led by Dr Seishi Shimizu, of the York Structural Biology Laboratory in the University's Department of Chemistry, shows that sugar has an important effect in reducing the bitterness of tea and coffee, not just by masking it but by influencing the fundamental chemistry.

Cancer cells in neuroblastoma contain a molecule that breaks down a key energy source for the body's immune cells, leaving them too physically drained to fight the disease, according to new research published in the journal Cancer Research today (Saturday).
Cancer Research UK-funded scientists have discovered that the cells in neuroblastoma - a rare type of childhood cancer that affects nerve cells - produce a molecule that breaks down arginine, one of the building blocks of proteins and an essential energy source for immune cells.

Cancer Research UK scientists have for the first time identified that there are five distinct types of prostate cancer and found a way to distinguish between them, according to a study in EBioMedicine.
The findings could have important implications for how doctors treat prostate cancer in the future, by identifying tumours that are more likely to grow and spread aggressively through the body.
The researchers, from the Cancer Research UK Cambridge Institute and Addenbrooke's Hospital, studied samples of healthy and cancerous prostate tissue from more than 250 men.

In patients with chronic kidney disease (CKD), atherosclerosis is exceedingly common and contributes to the development of heart disease, which is the leading cause of death in this group. New research suggests that an organic byproduct generated by intestinal bacteria may be responsible for the formation of cholesterol plaques in the arteries of individuals with decreased kidney function.

Cancer can be caused solely by protein imbalances within cells, a study of ovarian cancer has found.
The discovery is a major breakthrough because, until now, genetic aberrations have been seen as the main cause of almost all cancer.
The research, published today in the journal Oncogene, demonstrates that protein imbalance is a powerful prognostic tool, indicating whether or not patients are likely to respond to chemotherapy and whether a tumour is likely to spread to other sites.

A metabolic imbalance caused by radiation from your wireless devices could be the link to a number of health risks, such as various neurodegenerative diseases and cancer, according to a recent review which claims experimental data links metabolic effects of low-intensity radiofrequency radiation and living cells.

A biomarker found in the blood of alcohol users is significantly higher in binge drinkers than in those who consume alcohol moderately, according to a study by researchers at the University of Illinois at Chicago. The biomarker, called phosphatidylethanol (PEth), could be used to screen young adults for harmful or heavy drinking such as binge drinking.

University of Toronto researchers have discovered how severely damaged DNA is transported within a cell and how it is repaired.
It's a discovery that could unlock secrets into how cancer operates -- a disease that two in five Canadians will develop in their lifetime.
