Skin (Local Immune Response)

The skin's local immune response is a complex and dynamic process involving a variety of cell types and molecular mediators. It serves as the first line of defense against pathogens and injury, and plays a critical role in maintaining tissue homeostasis. The major components include keratinocytes, Langerhans cells, dermal dendritic cells, macrophages, fibroblasts, mast cells, and neutrophils, which interact to recognize, respond to, and resolve threats at the site of entry. Key mechanisms involve pattern recognition receptor activation, cytokine production, antigen presentation, effector cell recruitment, and resolution/homeostasis.
