Question

A woman goes to the doctor and is diagnosed with rheumatoid arthritis. What factors led to her developing this disease? Select all that apply. Some of her T cells were not negatively selected. Some of her T cells are not recognizing and associating with her major histocompatibility complex (MHC) proteins. Some of her T cells were not positively selected. Some of her T cells are recognizing and responding to her self antigens.

Answer 1

Answer:

Some of her T cells are recognizing and responding to her self antigens.

Explanation:

Rheumatoid arthritis is characterized as an inflammation in the joints. This inflammation is created by some T cells and their associations with antigens.

Right at the initial stage of the disease, T cells are activated by their own antigens, which makes them respond to this activation by recruiting monocytes and creating antibody-producing cells from the B lymphocyte. T cells also cause the release of free radicals and lysosomal enzymes, in addition to promoting an activation of the high imne complex. All of this, attacks the joints causing an inflammatory process at the site, which justifies the autoimmune character of this disease.

Autoimmune diseases are those in which the elements of an organism's immune system attack the healthy cells of the organism itself, as we can see in the paragraph above.
