Scientists discover coronavirus’s mechanism for inhibiting the immune system

The video explains how the novel coronavirus uses a protein called NSP1 to disrupt the host cell's ribosomes, preventing them from signaling the immune system. NSP1 binds to the 40S subunit of ribosomes, blocking their function and weakening the body's defense against infections.

What is the role of ribosomes in the cell?

• To transport molecules across the cell membrane

• To store genetic information

• To interact with RNAs to produce proteins

• To produce energy for the cell

How does the novel coronavirus use NSP1?

• As a structural component of the virus

• As a weapon to disrupt ribosomes

• To enhance the immune response

• To replicate its genetic material

Which subunit of the ribosome does NSP1 affect?

• 50S

• 60S

• 30S

• 40S

What is the result of NSP1 binding to the ribosome?

• Activation of antiviral defenses

• Increased cell division

• Inhibition of immune signaling

• Enhanced protein synthesis

What is the ultimate consequence of NSP1's action on the immune system?

• Strengthening of immune defenses

• Increased production of antibodies

• Collapse of a major line of defense

• No effect on the immune system
