Summary Introduction
Introduction:
The immune system can be defined as the organs and body processes that resist the infection and toxins. This system includes the organs such as bone marrow, thymus, and lymph nodes. Helper T cells are the most significant cells in adaptive immunity. These are needed for about all the adaptive immune responses. These cells aid in the activation of B-cells to release the antibodies and macrophages to destroy the consumed microbes. In addition, they help in the activation of cytotoxic T-cells to destroy the infected target cells.

- Which of the following is NOT an event that can result in an autoimmune disease? Which of the following is NOT an event that can result in an autoimmune disease? binding of a T cell to an antigen without receiving a co-stimulatory signal activation of self-reactive lymphocytes that survived negative selection genetic mutations causing changes in the structure of self-antigens cross-reaction of antibodies produced against foreign antigens with self-antigensarrow_forwardWhich of the following defines a memory cell? Microorganism that typically lives on the human body surface Self-protein on the surface of a vertebrate body cell Antigen-sensitized lymphocyte that forms in an immune response and acts immediately Long-lived antigen-sensitized lymphocyte that can act in a secondary immune responsearrow_forwardWhich of the following is not a component of an autoimmune response? The body's immune system targets its own tissues. Lymphocytes are produced that cannot discriminate between self and nonself. A normally harmless substance provokes an immune response in some people. An autoimmune response may be triggered by infection by a bacterium or virus such as HIV.arrow_forward
