Verified step by step guidance

Understand the concept of immune tolerance: Immune tolerance is the ability of the immune system to recognize and not attack the body's own cells and tissues. It is crucial for preventing autoimmune diseases.

Identify the role of immune tolerance: It helps in distinguishing between self and non-self antigens, allowing the immune system to target only foreign invaders while sparing the body's own cells.

Analyze the consequences of lacking immune tolerance: Without immune tolerance, the immune system may fail to differentiate between self and non-self, leading to the attack on the body's own cells, which can result in autoimmune diseases.

Evaluate each option: Consider how each option relates to the presence or absence of immune tolerance. Determine which option describes a scenario that would not occur if immune tolerance is lacking.

Conclude with the correct understanding: The option stating 'The immune system cells will only recognize and attack foreign antigens' is not a consequence of lacking immune tolerance, as lacking tolerance would lead to attacks on both foreign and self-antigens.
