Antiretroviral therapies (ART) stop HIV replication in its tracks, allowing people with HIV to live relatively normal lives. However, despite these treatments, some HIV still lingers inside cells in a dormant state known as “latency.” If ART is discontinued, HIV will awaken from its dormant state, begin to replicate, and cause acquired immunodeficiency syndrome (AIDS). […]

Multiple sclerosis (MS) is a neurological disease that usually leads to permanent disabilities. One key feature of the disease is that it causes the patient’s own immune system to attack and destroy the myelin sheaths in the central nervous system. Myelin sheaths ensure that electrical impulses travel quickly and efficiently from nerve cell to nerve […]

A new study led by researchers at the Marshall University Joan C. Edwards School of Medicine sheds light on the intricate interplay of brain regions involved in nicotine’s effects on the human brain. The research, published in eNeuro, an open-access, peer-reviewed scientific journal published by the Society for Neuroscience, explores how nicotine influences key areas […]

The capacity of intestinal stem cells to maintain cellular balance in the gut decreases upon ageing. Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and ageing. The finding may make a difference when seeking ways to maintain the functional capacity of the […]

Researchers with McMaster University and Denmark-based pharmaceutical company ALK-Abello A/S have made a groundbreaking discovery: a new cell that remembers allergies. The discovery gives scientists and researchers a new target in treating allergies and could lead to new therapeutics. “We’ve discovered a type of memory B cell that had unique characteristics and a unique gene […]

Rheumatoid arthritis is the most common type of inflammatory arthritis and affects 18 million people worldwide. It is a complex autoimmune disease characterized by chronic inflammation. This inflammation can cause the destruction of cartilage and bone, eventually leading to limitations, disabilities, loss of function, decreased quality of life, and possibly shortened life expectancy. “A major […]

A team of University of Wisconsin-Madison scientists has developed the first 3D-printed brain tissue that can grow and function like typical brain tissue. Printing methods have limited the success of previous attempts to print brain tissue, according to Zhang and Yuanwei Yan, a scientist in Zhang’s lab. Instead of using the traditional 3D-printing approach, stacking […]

Washington State University researchers measured the stress hormone cortisol in hair samples of 53 women in their third trimester. Of that group, 13 women who had elevated cortisol levels later experienced unpredicted birth complications, such as an early birth or hemorrhaging. “There was otherwise nothing about these women that would suggest a disease or anything […]
