Name the component which does not participate in innate immunity.

Hint: Natural immunity occurs when you become immune to a specific disease after contracting it. It is an important component of the host defence against infection. It is the second line of defence against non –self pathogens. Macrophages, DC’s and natural killer cells are the main immune cellular constituents responsible for innate responses.

Complete answer:
The innate immunity response is the first mechanism for host defence found in all multicellular organisms. The innate immunity system is more ancient than the acquired or adaptive immune response, and it has developed and evolved to protect the host from the surrounding environment in which a variety of toxins and infectious agents including bacteria, fungi, viruses and parasites are found. The immune system is complex and is divided in two categories 1) the innate or non specific immunity – which includes the natural barriers ( skin and mucosa ) and secretions. 2) the adaptive or specific immunity, which is targeted against a previously recognised specific microorganism or antigen.
Antibodies are the component which does not participate in innate immunity. The antibodies are part of innate immunity which gets activated after exposure to the pathogens. Antibodies are like special bodyguards that only recognize certain germs. Natural immunity triggers your immune system to make antibodies against the germ causing the infection inside of you.

Note: Innate immunity is the host’s first line of defence and is intended to prevent infection and attack the invading pathogens. Innate immunity comprises different components including physical barriers ; anatomical barriers ; epithelial and phagocytic cell enzymes, phagocytes, monocytes etc.
