The temporary boost in immune system activity due to brief stress is demonstrated through the function of which of the following?

• This temporary increase in immune activity is mainly due to acute stress response, which prepares the body for immediate challenges.
• This acute stress (short-term stress) initiates the Sympathetic Nervous System, leading to the release of stress hormones like adrenaline.
• These hormones provide a temporary boost to immune surveillance, helping the body respond quickly to threats.

Macrophages:

• Show increased phagocytic activity
• Faster pathogen recognition and clearance

T cells:

• Improved activation and proliferation
• Enhanced cell-mediated immunity

B cells:

• Stimulated antibody production
• Better humoral immune response

This coordinated activation represents a system-wide immune boost, not confined to just one type of cell.

Chronic stress, however, has the reverse effect, suppressing immune function.
