Study followed tracked over 1,500 older adults for a decade using three rounds of data from the National Social Life, Health and Aging Project. Led by Lissette Piedra, a professor of social work at the University of Illinois Urbana-Champaign; and James Iveniuk, a senior research scientist at the University of Chicago’s National Opinion Research Center; the team identified three types of social networks — enriched, focused and restricted — that reflected how socially connected people were as they aged and how their self-rated health was affected.

The single-celled parasite Entamoeba histolytica usually causes nothing worse than diarrhea, but sometimes it triggers severe, even fatal disease by chewing ulcers in the colon, liquefying parts of the liver and invading the brain and lungs. In a new paper, UC Davis researchers lay out a plan for tackling it, using genetic tools to tease apart the function of its proteins and genes.

A Ludwig Cancer Research study has identified a key mechanism by which advanced ovarian cancers suppress anti-tumor immune responses and resist immunotherapies.

New research led by Irish scientists has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body’s immune response in advanced ovarian cancer. The findings offer new insights into immune suppression in ovarian cancer and open promising avenues for future immunotherapy approaches.

Over 70% of patients with ovarian cancer are diagnosed at an advanced stage, often presenting with large volumes of ascites. This ascites fluid not only supports the spread of cancer throughout the abdominal cavity but also significantly impairs the body’s immune defences. Understanding how ascites affects the immune system is important for developing better treatments that use the immune system to fight cancer. 

In this recent study, researchers from Trinity College Dublin and University College Dublin explored how ascites disrupts immune cell function, with a particular focus on natural killer (NK) cells and T cells, which are key players in the body’s ability to eliminate tumours.
