Why Vitamin D Deficiency Can Raise Autoimmune Disease Risk

Image
  The body can naturally produce vitamin D when skin is exposed to sunlight, but this process declines significantly in winter. There also aren't many food sources of vitamin D. But vitamin D is very important to the body. The  vitamin D receptor  can be found in many different tissues, and while the vitamin's roles in bone health and calcium level maintenance are  well known , less is understood about its other functions, such as how it relates to immunity. Several immune cells have vitamin D receptors and gene activity in those cells can be affected by the vitamin. Low levels of vitamin D have also been associated with a variety of autoimmune disorders including inflammatory bowel disease, multiple sclerosis, psoriasis vulgaris, rheumatoid arthritis, and type 1 diabetes. Studies  have also shown  that vitamin D supplements can help lower the risk of autoimmune disease. A new study  reported in  Science Advances  has provided new insights in...

New Hybrid Cell Discovery Shakes Up Neuroscience

Image
Neuroscientists have unveiled a new hybrid cell, straddling the line between the well-known neurons and glial cells in the brain.Previously, glial cells, especially astrocytes, were believed to merely support neuron functions. However, recent research highlights the ability of these cells to release neurotransmitters and directly influence neural circuits.This groundbreaking discovery challenges traditional beliefs about brain cell functionality and paves the way for novel therapeutic strategies. Key Facts: A new hybrid cell type, located between neurons and astrocytes, has been identified that can release neurotransmitters. Modern molecular biology techniques confirmed that astrocytes possess machinery necessary for the rapid secretion of glutamate. Disruption of these hybrid cells’ functionality impacts memory, has links with epilepsy, and offers therapeutic insights for Parkinson’s disease. Source: University of Lausanne Neuroscience is in great upheaval. The two major families of c...

Uncovering the molecular drivers of liver cancer

Image
  Researchers discover that inflammation and aging contribute to non-viral liver cancer development. Green tea's role in reversing some of the pathway dysregulation that may contribute to the cancer development and other therapies explored. Liver cancer can arise spontaneously from healthy liver tissue. Recently, however, researchers have discovered an increasing correlation between some liver cancers and non-viral chronic liver disease (CLD). One liver cancer, hepatocellular carcinoma (HCC), is associated with CLD in about 15–25% of cases. While increasing awareness and screening of cancers has improved the ability to detect liver cancer at earlier stages when it is more effectively treated, cancer prevention is always a primary goal of both healthcare providers and biomedical researchers. The increasing prevalence of CLD with HCC suggests that this underlying condition predisposes liver tissue to cancer development. In order to investigate how healthy liver tissue differs from th...
