Question:
Neisseria gonorrhoeae pili bind to which receptor:
Neisseria gonorrhoeae pili bind to which receptor:
Show Hint
Gonorrhoeae + Pili $\rightarrow$ CD46.
Updated On: May 25, 2026
- CD14
- CD
- CD46
- CD4
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Pili (fimbriae) are hair-like appendages on the bacterial surface that mediate attachment to host cells.
Step 2: Meaning
Adhesion is a crucial first step in the pathogenesis of Neisseria gonorrhoeae.
Step 3: Analysis
The Type IV pili of the gonococcus specifically recognize and bind to CD46 (Membrane Cofactor Protein) on human epithelial cells.
Step 4: Conclusion
Binding to CD46 allows the bacteria to colonize the host mucosal surfaces. Final Answer: (C)
