Type 1 Diabetes Mellitus e. SLE Which of these autoimmune diseases is associated with the destruction of thyroid follicles? a. Myasthenia Gravis b. Hashimoto's Thyroiditis c. Graves Disease d. Type 1 Diabetes Mellitus e. SLE.Explanation / Answer
28) Reactivity with antibodies
Epitope are molecules present on antigens binding to antibodies and create immune response
29) Decrease count of B and T cell count
On antigenic infection the T cell direct B cell to produce antibodies but in case of immunodeficiency due to absence or less count T cells less number of B cells are produced.
30) It is specific for a given organ
Innate immunity is the type of immune responses which develops immunity for specific organs
31) Normal B cell and decrease T cell count
During the HICV infection the T cytotoxic are affected first and T cytoctoxic cell develop cell mediated immunity during this stage the B cell counts remains normal once all T cells are destroyed later B cell developed develops Humoral mediated response.
32) Type 1 diabetes mellitus
Type 1 diabetes mellitus is causes bye destruction of pancreatic beta cells by autoimmune disease. Beta cell-cytotoxic CD8+ T cells act synergistically to destroy beta cells, resulting in autoimmune type 1 diabetes .
33) Hashimoto's thyroiditis
Hashimoto's thyroiditis is a autoimmune disease in which antibodies turn against own body tissues and attacking thyroid by which thyroid will not be able to make sufficient hormones.
