Study elucidates how Omega-3 fatty acids poison tumor cells

Study elucidates how Omega-3 fatty acids poison tumor cells

So-called “good fatty acids” are essential for human health and much sought after by those who try to eat healthily. Among the Omega-3 fatty acids, DHA or docosahexaenoic acid is crucial to brain function, vision and the regulation of inflammatory phenomena. In addition to these virtues, DHA is also associated with a reduction in the …

Study reports compound blocks SARS-CoV-2 and protects lung cells

Credit: CC0 Public Domain Research conducted at LSU Health New Orleans Neuroscience Center of Excellence reports that Elovanoids, bioactive chemical messengers made from omega-3 very-long-chain polyunsaturated fatty acids discovered by the Bazan lab in 2017, may block the virus that causes COVID-19 from entering cells and protect the air cells (alveoli) of the lung. Their …

Study examines the effects of COVID-19 on human kidney cells

Credit: CC0 Public Domain Researchers have studied human kidney cells in the lab to examine the effects of COVID-19 on kidney health. The findings appear in an upcoming issue of JASN. Many individuals who develop COVID-19 also experience kidney damage, but it’s unclear if this is a direct result of viral infection or a consequence …

Non-altered birth cord cells boost survival of critically ill COVID-19 patients

Non-altered birth cord cells boost survival of critically ill COVID-19 patients

Credit: CC0 Public Domain Critically ill COVID-19 patients treated with non-altered stem cells from umbilical cord connective tissue were more than twice as likely to survive as those who did not have the treatment, according to a study published today in STEM CELLS Translational Medicine. The clinical trial, carried out at four hospitals in Jakarta, …

Microgel coating gives donor cells a boost in reversing pulmonary fibrosis

Microgel coating gives donor cells a boost in reversing pulmonary fibrosis

Gel-coated (red) mesenchymal stromal cells (yellow) can degrade collagen (green) over a distance in the presence of tumor necrosis factor-alpha. Credit: Jae-Won Shin and Sing-Wan Wong/UIC Researchers at the University of Illinois Chicago have shown that even after lung tissue has been damaged, it may be possible to reverse fibrosis and promote tissue repair through …

New bioengineered reporter system allows to follow protein isoform expression over time in live cells

New bioengineered reporter system allows to follow protein isoform expression over time in live cells

Our proteome is much bigger than our genome because one gene produces several variants of proteins called protein isoforms, whose disbalance is implicated in many diseases. A new bioengineered reporter system developed at Helmholtz Zentrum München and the Technical University of Munich now allows for the first time to follow protein isoform expression over time …

Scientists shed light on action of key tuberculosis drug

Deficient immune cells implicated in TB disease progression

Scanning electron micrograph of Mycobacterium tuberculosis bacteria, which cause TB.  Credit: NIAID Nearly a quarter of the world’s population is estimated to be infected with Mycobacterium tuberculosis (M.tb), the pathogen that causes tuberculosis, but less than 15 percent of infected individuals develop the disease. A study published May 24 in Nature Immunology by investigators from Harvard Medical …

Study reveals how HIV prevents the maturation of myelin-making brain cells

Study reveals how HIV prevents the maturation of myelin-making brain cells

It’s long been known that people living with HIV experience a loss of white matter in their brains. As opposed to “gray matter,” which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping them transmit signals quickly and …

Scientists experimentally boost red blood cells to aid sickle cell and other hemoglobin diseases

Scientists experimentally boost red blood cells to aid sickle cell and other hemoglobin diseases

Credit: National Institutes of Health A series of laboratory studies is underway in the United States to improve gene therapy worldwide for sickle cell disease, a complex and sometimes deadly heritable blood disorder that dramatically affects the structure and function of oxygen-ferrying red blood cells. Sickle cell disease is a devastating disorder that largely affects …
