The study led by Christine Beeton from Baylor College of Medicine in the US shows that nanoparticles modified with polyethylene glycol (PEG) are conveniently choosy as they are taken up by cells in the immune system.That could be a plus for patients with autoimmune diseases like multiple sclerosis, researchers said.
“Placed just under the skin, the carbon-based particles form a dark spot that fades over about one week as they are slowly released into the circulation,” Beeton said.T and B lymphocyte cells and macrophages are key components of the immune system.However, in many autoim mune diseases like multiple sclerosis, T cells are the key players. One suspected cause is that T cells lose their ability to distinguish between invaders and healthy tissue and attack both.
“The ability to selectively inhibit one type of cell over others in the same environment may help doctors gain more control over autoimmune diseases,” Beeton said.
