mucosal cytokines

Mucosal cytokines are small proteins that act as messengers in the immune system, specifically at mucous membrane sites like the nose, throat, and gut. They help coordinate the body's response to infections, inflammation, or other immune challenges by signaling immune cells to activate, gather, or suppress activity. These cytokines are crucial for maintaining the balance between defending against pathogens and preventing excessive inflammation that can damage tissues. Understanding mucosal cytokines provides insight into how our bodies protect mucous-lined areas from illness and can inform treatments for respiratory and gastrointestinal diseases.
