Study reveals how COVID-19 infects human cells

The video explains how SARS-CoV-2 infects humans by targeting specific receptors on human cells, particularly in the lungs, heart, kidneys, and intestines. It highlights the role of the virus's spy protein, which has receptor-binding domains (RBDs) that facilitate binding and invasion of human cells. The virus specifically targets a unique AS2 receptor structure, which is bonded with an amino acid transporter, allowing the virus to enter and infect cells. This discovery could aid in developing a cure or vaccine by targeting the AS2 receptor.

Which organs are mentioned as being targeted by SARS-CoV-2?

• Brain, liver, and pancreas

• Eyes and ears

• Lungs, heart, kidneys, and intestines

• Skin and muscles

What is the role of the receptor-binding domains (RBDs) in the virus's spike protein?

• They help the virus to replicate

• They allow the virus to bind to human cells

• They provide energy to the virus

• They destroy human cells

How many receptor-binding domains are facing downward in the virus's spike protein?

• Four

• Two

• Three

• One

What is unique about the AS2 receptor targeted by the virus?

• It is located in the brain

• It is resistant to the virus

• It has a previously undiscovered subtype

• It is found only in animals

How might the discovery of the AS2 receptor's interaction with the virus help researchers?

• By eliminating the need for vaccines

• By increasing the virus's spread

• By developing a cure or vaccine

• By making the virus more potent
