Key Concepts

Immunomodulation and Stress

Immunomodulation refers to the process by which the immune system is regulated by internal and external factors, including stress. The interactions between stress and the immune system are complex; while acute stress may enhance certain immune functions, chronic stress typically leads to dysregulation and suppression of both innate and adaptive immune responses.

Natural (Innate) Immunity

Natural or innate immunity is the first line of defense against pathogens and consists of rapid, non-specific mechanisms that respond immediately to invaders. It involves physical barriers, immune cells like macrophages and neutrophils, and various proteins that collectively provide an initial protective response.

Specific (Adaptive) Immunity

Specific or adaptive immunity is a more specialized defense system that identifies and targets specific pathogens. This component of the immune system develops immunological memory through the activation of B-cells and T-cells, allowing for a stronger and faster response upon subsequent exposures to the same pathogen.

Chronic Stress

Chronic stress is characterized by prolonged and continuous exposure to stressors, leading to sustained activation of the stress response. Over time, this can disrupt normal immune function, often resulting in immunosuppression and a diminished ability to mount effective responses, both in innate and adaptive immunity.

Acute Stress

Acute stress refers to a short-term physiological response to a stressor that results in rapid activation of the body's systems. In the context of immunology, acute stress can transiently enhance certain immune functions by mobilizing immune cells and increasing their efficiency, which may temporarily boost both natural and specific immune responses.

True or False? Short-term acute stressors increase both natural and specific immunity, whereas chronic stressors increase only natural immunity.
