What are the main differences between innate and adaptive immunity?

What are the main differences between innate and adaptive immunity?

The main difference between innate immunity and adaptive immunity is that innate immunity generates a non-specific immune response against the pathogen whereas adaptive immunity generates a specific immune response against a particular pathogen.

What are three differences between innate and adaptive immunity?

The innate immune response is activated by chemical properties of the antigen. Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized.

What is a characteristic of adaptive immunity but not innate immunity?

Unlike the innate immune system, which attacks only based on the identification of general threats, the adaptive immunity is activated by exposure to pathogens, and uses an immunological memory to learn about the threat and enhance the immune response accordingly.

How innate and adaptive immunity coordinate with each other?

The innate immune response to microbes stimulates adaptive immune responses and influences the nature of the adaptive responses. Conversely, adaptive immune responses often work by enhancing the protective mechanisms of innate immunity, making them more capable of effectively combating pathogenic microbes.

Why the adaptive immune system is known as adaptive?

This acquired response is called “adaptive” because it prepares the body’s immune system for future challenges (though it can actually also be maladaptive when it results in allergies or autoimmunity).

Are antibodies innate or adaptive?

Innate and Adaptive Immunity

Innate Adaptive
Blood proteins Complement, others Antibodies
Cells Phagocytes (macrophages, neutrophils), natural killer cells, innate lymphoid cells Lymphocytes
