Study Notes
Types of Immunity
- Innate immunity provides an immediate, nonspecific response to pathogens and is mediated by cells such as neutrophils, macrophages, and dendritic cells.
Characteristics of Immunity
- Adaptive immunity requires recognition of a foreign antigen before producing a response, which takes time.
Key Features of Adaptive Immunity
- The main characteristic that distinguishes adaptive immunity from innate immunity is the ability to recognize and remember specific pathogens, allowing for a more targeted response.
Immunity against Antigens
- Adaptive immunity is responsible for fighting off non-changing antigens, such as those found in viruses and toxins.
