How does the host cell recognize a viral infection?

Host cells use specialized receptors called Pattern Recognition Receptors, such as TLR7 and TLR8, to detect viral components like RNA. Once these sensors identify the virus, they trigger signaling molecules like MyD88. This process initiates a cascade that activates transcription factors, leading to the production of interferons and cytokines to stop the virus from spreading further.

What role do mitochondria play in the immune response?

Mitochondria act as vital hubs for immune signaling and cellular stress detection during an infection. They can release reactive oxygen species and proteins like Cytochrome C to trigger apoptosis, or programmed cell death. This prevents the virus from hijacking the cell's machinery for replication, effectively sacrificing the infected cell to protect the rest of the host organism.

What is a cytokine storm and why is it dangerous?

A cytokine storm is an overactive immune response where the body releases too many inflammatory proteins, such as IL-6 and TNF-alpha, into the blood too quickly. This can lead to widespread tissue damage, organ failure, and blood clotting issues like thrombosis. It represents a breakdown in immune regulation where the body's defense system begins harming itself.

Viral Entry and Host Defense Mechanisms

Viral infections trigger complex defense mechanisms within the human body. This diagram illustrates how viruses like SARS-CoV-2 enter cells and activate immune pathways. Understanding these interactions helps researchers develop treatments. It highlights the balance between cellular protection and the risks of excessive inflammation, such as dangerous cytokine storms.
