Myeloid immune cells in the blood tied to severe COVID-19

Individual variations in how the immune system responds to SARS-CoV-2 appear to impact the severity of disease. Researchers at Karolinska Institutet in Sweden have now been able to show that patients with severe COVID-19 have significantly elevated levels of a certain type of immune cells in their blood, called myeloid-derived suppressor cells. The study published […]

Immune system killer cells controlled by circadian rhythms

An analysis of an exhaustive dataset on cells essential to the mammalian immune system shows that our ability to fight disease may rely more heavily on daily circadian cycles than previously assumed. Malfunctions in circadian rhythms, the process that keeps our bodies in tune with the day/night cycles, are increasingly associated with diabetes, cancer, Alzheimer’s, […]

Researchers develop new way to watch pancreatic cells package insulin

For the first time, scientists have peered deeply inside a pancreatic cell and observed it packaging insulin and responding to a drug treatment, an intimate look at the mechanisms responsible for preventing diabetes. A team of scientists—led by researchers at the Bridge Institute at the USC Michelson Center for Convergent Bioscience—have developed advanced imaging techniques […]

A more sensitive way to detect circulating tumor cells

Breast cancer is the most frequently diagnosed cancer in women, and metastasis from the breast to other areas of the body is the leading cause of death in these patients. Detecting circulating tumor cells (CTCs) in the bloodstream could help doctors find and treat metastases at an earlier stage, increasing chances of survival. Now, researchers […]
