How skin cells communicate with each other
In human biology, one of the most fascinating evolutionary traits we’ve developed is cell signaling or, put another way, the ability your cells have to effectively communicate with one another. In fact, in all aspects of human existence, we have put all our time, energy, and money into figuring out ways we can better communicate with our friends, family, and colleagues across the globe. While technology dominates the medium in which humans communicate with the rest of the world, the conversation happening between your cells is mediated by biological chemicals known as cytokines. This ubiquitous class of chemicals, that also includes growth factors and chemokines, are known collectively as “protein messenger molecules” that act as the language of your cells, and it’s what all your cells (except red blood cells and corneocytes) use to literally communicate with each other, effectively coordinating all biological activity. These biological signals are necessary for life itself, and they play a significant role in keeping our body and skin healthy.
