Adaptive immunity is a specialized part of the immune system that develops over time in response to specific pathogens. Unlike innate immunity, which acts quickly, adaptive immunity provides a targeted and long-lasting response.
Key Features:
- Specificity: Targets specific pathogens like bacteria and viruses.
- Memory: Creates memory cells after initial exposure, enabling a faster response to future infections.
-
Components:
- B Cells: Produce antibodies to neutralize pathogens.
- T Cells: Include helper T cells (assist other immune cells) and cytotoxic T cells (destroy infected cells).
Importance:
- Provides long-lasting immunity against specific infections.
- Essential for the effectiveness of vaccines.
- Dysregulation can lead to autoimmune diseases.
Supporting Adaptive Immunity:
- A balanced diet and probiotics may enhance immune function and responses.
