Afghanistan's rare earth element bonanza. After more than a decade of war and nation building, members of the International Security Assistance Force (ISAF) in Afghanistan are heading for the exits. Although what ISAF will leave behind is better than what was there in 2001, Afghanistan remains a battered land.
Immune Function. Your immune system relies heavily on proteins. When your body is exposed to potentially harmful substances, such as bacteria or a virus, your immune system sends out proteins called antibodies.These antibodies seek out and attack the virus or bacterium in an attempt to neutralize it and prevent it from multiplying and causing illness.rotein is considered a macronutrient, which means that your body needs it in large amounts every day to function properly. When you eat protein, your body breaks it down into amino acids that are used for several purposes.
Antibodies are proteins produced by the immune system that bind to a target antigen on the cell surface. The immune system normally uses them to fight pathogens. Each antibody is specific to one or a few proteins. Those that bind to tumor antigens treat cancer. Cell surface receptors are common targets for antibody therapies and include CD20, CD274 and CD279.
