The virus that causes AIDS, Human Immunodeficiency Virus (HIV) , infects about one million people globally every year. The virus needs to sneak its genetic material into the cell nucleus and integrate it into a chromosome in order to replicate and spread the infection. Its capsid has now been found to have developed into a molecular transporter by research teams led by Thomas Schwartz at MIT and Dirk Görlich at the Max Planck Institute for Multidisciplinary Science. Consequently, it has the ability to directly cross a critical barrier that typically shields the cell nucleus from viral intruders. This method of smuggling prevents anti-viral sensors in the cytoplasm from seeing the viral genome. Though we now have treatments that successfully contain the infection, there is still no cure for AIDS, which was first linked to the human immunodeficiency virus (HIV) forty years ago. The virus replicates and multiplies by infecting specific immune cells and taking over their genetic programmin...

Source – Neuroscience News Nestled within the intricate labyrinth of the human body lies a remarkable frontier – the blood-brain barrier (BBB) . This selective gatekeeper stands guard between the gushing torrent of our bloodstream and the delicate ecosystem of the brain. Unlike most tissues, the brain doesn’t readily embrace everything circulating in our blood. It demands a high level of security, a filter to ensure only essential substances gain entry, and potentially harmful intruders are kept at bay. Understanding this fascinating barrier is akin to deciphering a secret code, unlocking the mysteries of how our brains stay protected and function optimally. What is the Blood-Brain Barrier? Imagine a tightly woven net lining the blood vessels within the brain. This specialized network of endothelial cells, along with supporting proteins and tight junctions, forms the formidable blood-brain barrier. Unlike leaky vessels elsewhere in the body, the BBB strictly regulates what passes throu...

Source-News-Medical Multiple sclerosis (MS) is a chronic and often disabling neurological disorder that affects the central nervous system (CNS), including the brain and spinal cord. With its complex nature, MS poses challenges for those living with the condition and the healthcare professionals dedicated to managing it. In this comprehensive article, we delve into the main causes of multiple sclerosis, explore the potential for a long life with MS, understand the physiological effects of the condition, and discuss the current state of MS management. What is the Main Cause of Multiple Sclerosis? The exact cause of multiple sclerosis remains elusive, and it is believed to result from a combination of genetic and environmental factors. While researchers have made significant strides in understanding the disease, pinpointing a singular cause has proven challenging. A. Immunological Basis One prevailing theory suggests that MS is an autoimmune disorder, wherein the body’s immune system mi...
