What Makes Our Skin Immune to Infections?
Our skin gets its immunity due to density and distribution of immune cells which work as the soldiers in our body, according to a study by Sangbum Park, Asst Professor at Michigan State University who works in the Institute for Quantitative Health Science & Engineering.
It was German Scientists Paul Langerhans who first discovered one type of immune cells in the skin in late 1800's but mistook it for cells of the nervous system. It cam eb to be called Langerhans cells.
New studies at MSU have shown that our outermost layer of skin, the epidermis, is home to immune cells. Using advanced microscopy tools, Sangbum Park and and his team have found out the structure and function of skin in live mice that shows the Langerhans and dendritic epidermal T cells.
My lab is interested in how skin regenerates and recovers from injury,” he said. That injury could be a cut, an infection, an allergic reaction or an even more persistent disorder, such as psoriasis. “We can answer so many questions with our intravital imaging technique that you just can’t with conventional methods.”
