Final answer:
If immune synapses do not function, the body's response to pathogens is compromised, leading to increased susceptibility to diseases and a diminished ability to fight infections due to the critical role these synapses play in immune cell coordination and activation.
Step-by-step explanation:
If immune synapses do not function properly, b) the body's response to pathogens is compromised. Immune synapses are critical for the activation and proper functioning of immune cells, allowing them to effectively recognize and respond to pathogens. Without functioning immune synapses, immune cells may be unable to effectively coordinate a response to infections, resulting in increased susceptibility to diseases and a diminished ability to clear infections. This scenario aligns with the concept of immunodeficiency, which can lead to heightened vulnerability to infections and other diseases.
It's important to note that the result of nonfunctioning immune synapses differs from the other possibilities listed, such as overactive immune systems, or situations where there is no impact on immune function. In cases where immune synapses fail, the issue lies with an underactive or inadequate immune response, rather than an overactive or benign one.
