Langerhans cells
Langerhans cells are specialized immune cells found in the skin and mucosal tissues. They play a crucial role in detecting and responding to foreign invaders, such as bacteria and viruses. When they encounter these harmful substances, Langerhans cells capture and process them, then travel to lymph nodes to alert other immune cells. This helps initiate a stronger immune response to protect the body. Their unique shape and location make them essential in maintaining skin health and defending against infections, highlighting their importance in our overall immune system.

Langerhans cells are a type of immune cell found in the skin and some other tissues. They play a vital role in the body’s defense system by detecting foreign invaders, like bacteria and viruses. Acting as sentinels, these cells capture and process antigens (substances that trigger an immune response), then travel to lymph nodes to alert other immune cells. This helps the body mount a response to infections or other threats. Their presence is crucial for maintaining skin health and immune function, making them an important part of our overall defense against disease.
