Immune cells

Available for over a year

Every day, billions of specialised cells work to protect your body from harm. From the common cold and infections to cuts and scrapes or cancerous cells, our bodies deal with a range of potential threats and risks as we move through the world. The immune system is a complex and carefully orchestrated network connecting organs, tissues, and billions of specialised cells. Those cells have a variety of different roles as they respond to pathogens or harm, including engulfing microbes, identifying damage, or producing antibodies. Misha Glenny and his guests examine the different types of cells involved in an immune response, how they know what to respond to, and what happens when those cells aren’t working as they should. This In Our Time episode discusses why our immune cells are vital to life – both for us as individuals, and as a species. The discussion explores the interconnected nature of the immune system, and what we know actually affects the way our immune cells function.
