Plasmacytoid dendritic cells

Plasmacytoid dendritic cells are a specialized type of immune cell that play a key role in defending the body against viruses. They recognize viral infections and quickly produce large amounts of a protein called interferon, which helps activate other immune cells and inhibit virus replication. These cells are part of the body's innate immune system, providing an early response to infection, and also help shape longer-term immunity. They are particularly important in controlling viral diseases like influenza and HIV, and their proper functioning is crucial for maintaining immune health.
