Study Notes
Dendritic Cells Overview
- Dendritic cells play a crucial role in the immune system by processing and presenting antigens to T cells, thus initiating adaptive immune responses.
- They act as key linkers between the innate and adaptive immunity.
Potency in Antigen Processing
- Myeloid dendritic cells are approximately 100 times more effective in antigen processing compared to macrophages and B cells, making them essential for immune activation.
Fate of Immature Dendritic Cells
- Immature dendritic cells that do not encounter antigens undergo apoptosis, preventing the potential activation of immune responses in the absence of infection or injury.
Activation of Naive T Cells
- Conventional dendritic cells are specialized in activating naive T cells and are critical for triggering a primary immune response, ensuring the body can respond to new pathogens effectively.
Production of Interleukin 12 (IL-12)
- Plasmacytoid dendritic cells are responsible for producing Interleukin 12 (IL-12), which plays a pivotal role in activating Th1 cells, contributing to the immune response against intracellular pathogens.
