Answer:
A. While the positive feedback loop between cytokines and the immune system fights off the viral infection, it also promotes secondary infections and cell death, which prevent a return to homeostasis.
Explanation:
During a cytokine storm, there is an excessive and uncontrolled release of pro-inflammatory cytokines, which are signaling molecules involved in immune response. While these cytokines play a crucial role in initiating and coordinating the immune response to eliminate the viral infection, an excessive production can lead to harmful effects.
In the case of a cytokine storm, the positive feedback loop between cytokines and the immune system becomes dysregulated. The excessive cytokine production leads to a hyperactive immune response, resulting in tissue damage, organ dysfunction, and systemic inflammation. This can cause secondary infections as the immune system becomes overwhelmed and compromised. Additionally, the excessive inflammation and cell death can disrupt normal physiological processes, preventing the organism from returning to homeostasis.
