A new tool for studying COVID’s impact on gut health

Researchers developed a human Intestine Chip to study coronavirus infection and test potential treatments. The chip showed that nafamostat reduced virus presence while remdesivir damaged intestinal tissue, offering insights into underlying causes of GI symptoms and improving understanding of treatment efficacy and toxicity.

Adult stem cells transform faster with two lasers

Scientists from the University of Johannesburg found that shining two lasers on adult stem cells accelerates their transformation into different types of cells. The consecutive irradiation increases proliferation and differentiation under laboratory conditions, paving the way for potential therapies to repair damaged tissues.

Rare COVID-19 response in children explained

A Yale-led study discovered that children with multi-system inflammatory response (MIS-C) exhibit unique immune system signatures, including elevated alarmins and adaptive immune responses. These findings may aid in diagnosis and early treatment of the condition, which can be fatal if left untreated.

Radiation vulnerability

A new study reveals that the behavior of p53, a key tumor-suppressor protein, over time determines whether tissues can survive radiation exposure. In vulnerable tissues, p53 levels remain high, leading to cell death, while in more radioresistant tissues, p53 levels oscillate, allowing cells to survive.

Marine mammals' adaptations to low oxygen offer new perspective on COVID-19

A study by UC Santa Cruz professor Terrie Williams explores how marine mammals' physiological adaptations can help understand the effects of COVID-19. Marine mammals have evolved mechanisms to protect critical organs during low-oxygen conditions, which may inform strategies for humans to mitigate long-term damage from oxygen deprivation.

Cellular survivors

Researchers have identified two key factors involved in cellular recovery from extreme stress, which may provide new strategies for treating cancers. The study reveals that apoptosis is a more nuanced process than previously known, and sometimes cells survive the executioner caspase via anastasis.

UC Davis researchers find a way to help stem cells work for the heart

Researchers at UC Davis Health have made a breakthrough in using stem cell treatments for heart disease. By blocking an enzyme linked with inflammation, they were able to increase the survival of transplanted stem cells and improve cardiac function. This discovery could lead to a cellular-based treatment for heart failure.

Neutrophils are equipped with a 'disarmament' program that prevents the immune system going 'out of control'

Researchers at CNIC discovered a 'disarmament' mechanism in neutrophils that reduces their toxic capacity to prevent damage to healthy tissues. This innate system, driven by CXCR2 and circadian rhythms, helps regulate the immune response and could have implications for treating conditions like myocardial infarction and stroke.
