- Sialic acid
- CD4
- CD81
- Claudin-1
The Correct Option is B
Solution and Explanation
Step 1: Concept
HIV-1 infection begins with the attachment of the viral envelope glycoprotein gp120 to a specific receptor on the surface of host cells.
Step 2: Identification
The primary receptor for HIV-1 is the CD4 molecule, found predominantly on Helper T cells, macrophages, and dendritic cells.
Step 3: Reasoning
CD81 is a receptor for Hepatitis C, and Sialic acid is used by Influenza. HIV specifically targets CD4+ cells.
Step 4: Conclusion
The receptor for HIV-1 is CD4. Final Answer: (B)
