What role do some T cells play in enhancing the innate immune response?
What role do some T cells play in enhancing the innate immune response?
- Producing antibodies that mark pathogens for attack
- Providing a rapid, pre-existing response to infection
- Recognizing a wide repertoire of foreign substances
- Secreting cytokines that increase the ability of macrophages to kill ingested microbes (correct)
What is a key difference between the innate and adaptive immune responses?
What is a key difference between the innate and adaptive immune responses?
- The ability to recognize a wide repertoire of foreign substances, with innate responses being more limited (correct)
- The reliance on lymphocytes, with adaptive responses being more dependent on them
- The speed of the response, with innate responses being slower
- The ability to improve during a response, with innate responses being more effective initially
What is the role of antibodies in the innate immune response?
What is the role of antibodies in the innate immune response?
- Marking pathogens for attack by complement and serving as a potent activator of the attack (correct)
- Producing cytokines that increase the ability of macrophages to kill ingested microbes
- Recognizing a wide repertoire of foreign substances
- Providing a rapid, pre-existing response to infection
