Question

What proteins are fundamental to the immune system?

Answer 1

Hint: The immune system is a network of cells and proteins that protects the body from infection. The immune system keeps track of any germ (microbe) it has ever overcome so that it can easily recognise and eliminate the microbe if it re-enters the body.

Complete answer:
The proteins cytokines and antibodies are necessary for the immune system to function.

Cytokines are small proteins that act as immune system signalling molecules. They are a diverse array of proteins, peptides, and glycoproteins secreted by immune system cells. Cytokines are a type of signalling molecule that plays a role in immune function, inflammation, and hematopoiesis. They are in charge of coordinating the immune system's different cell types' responses. Antibodies are proteins that bind to foreign molecules and neutralise or tag them so that they can be removed by other immune cells.

Antibodies are important elements of the immune system. They are proteins that help in the activation of the immune system and the resulting launch of an immune response. Antibodies are located on a number of cell types, including macrophages, B-cells, T-cells, dendritic cells, and others, and are active in the development of long-term memory. Antibodies secreted into the bloodstream identify and target pathogens for detection by immune system microbicidal cells.

Antibodies are specialised, Y-shaped proteins that attach to foreign pathogens in the body, whether they are viruses, bacteria, fungi, or parasites, like a lock and key. They're the immune system's search-and-destroy system's "search" battalion, tasked with locating an enemy and marking it for death.
When antibodies locate their mark, they bind to it, triggering a series of events that defeat the invader. Antibodies are part of the immune system's "adaptive" arm, which learns to identify and remove particular pathogens, according to Greene.

Note: Proteins are the essential nutrients needed by our body. Protein is a macronutrient that is needed for muscle growth. It is most often found in agricultural products, but it can also be found in nuts and legumes. Milk, cheese and meat are also good sources of proteins.
