How does the body respond to a pathogen?

The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.

Why is the secondary response to a pathogen faster?

Because of the generation of memory cells, the secondary immune response is faster and stronger, leading to more effective pathogen elimination in comparison to the primary immune response.

How does the body respond when a pathogen first enters the body?

Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. Cytokines such as interferons are molecules that signal neighbouring cells and induce an antiviral state in them. These cells are then primed to resist an infection with the invading virus.

What happens the second time an animal is exposed to an antigen?

A clone continues to grow after lymphocytes first encounter an antigen so that, if the same type of antigen invades the body a second time, there will be many more lymphocytes specific for that antigen ready to meet the invader This is a crucial component of immunologic memory.

What animal has the strongest immune system?

Ostriches

Does autoimmune disease start in the gut?

Protein produced by common gut bacteria may trigger the onset of autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and ulcerative colitis.

What diet is best for autoimmune disease?
