The release of which cytokines is triggered by bacterial or viral infections,cancer,and tissue injury that in turn initiate a stress response?

Question

Quizplus · Accepted Answer

Interferon, tumor necrosis factor ß, and interleukin 6 (Il-6) are released in response to bacterial or viral infections, cancer, and tissue injury. These cytokines initiate a stress response by activating the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, leading to the release of cortisol and catecholamines, respectively. This stress response helps to limit the spread of infection and promote tissue repair but prolonged or excessive activation can lead to detrimental effects on health. Il-1 and Il-2 are primarily involved in immune activation and regulation, while Il-12, tumor necrosis factor, and colony stimulating factor are involved in the differentiation and activation of immune cells. Il-4 and Il-24 are mainly involved in allergic and inflammatory responses.
