How Immune Cells Navigate Through The Skin By Sensing Graded Patterns Of Immobilized Directional Cues

Immune cells constantly patrol our body to check for foreign invaders, such as bacteria or viruses. To do so they leave the blood stream, actively crawl through tissues and finally re-enter the circulation via lymphatic vessels. Research from the laboratory of Michael Sixt elucidates how the cells are guided through tissues like the skin. It is thought that cells either sense their environment by 'touching' or 'smelling': They adhere to structural molecules like connective tissue proteins using adhesion receptors. Or they 'smell' soluble signal molecules with specialized surface receptors... via Health News from Medical News Today Read More Here..
