The cell membrane is impermeable to viruses: to get inside and infect a cell, they use a range of strategies to exploit the cellular and biochemical properties of the membranes. The thiol-mediated uptake of organic molecules similar to alcohols, where oxygen is replaced by a sulfur atom, is one of the entry mechanisms, with its use by Human Immunodeficiency Virus (HIV) … [Read more...]

Physical activity in all of its forms may help maintain muscle mass in midlife
A large study of middle-aged women shows that age-related changes in skeletal muscle are part of everyday life for women in their fifties. During this time, women transition from perimenopause to postmenopause and the production of estrogen ceases. Loss of estrogen has an effect on muscles and leads to a decline in muscle mass. Physical activity in all of its forms may help … [Read more...]

Antibodies: The body’s own antidepressants
If the immune system attacks its own body, it can often have devastating consequences: autoantibodies bind to the body's structures, triggering functional disorders. The receptors for glutamate, a neurotransmitter, can also become the target of autoantibodies. Researchers at the Max Planck Institute of Experimental Medicine in Göttingen have been investigating the circumstances … [Read more...]
