All of the Following Can Contribute to Reduced Leukocyte Chemotaxis

Question

All of the following can contribute to reduced leukocyte chemotaxis in the renal medulla, except
A) high ammonia concentration.
B) hyperosmolarity.
C) reduced water reabsorption.
D) sluggish blood flow.

Accepted Answer

Reduced water reabsorption would actually increase leukocyte chemotaxis in the renal medulla by creating a more concentrated gradient. A and B are true statements that can contribute to reduced leukocyte chemotaxis, and D can also contribute by reducing the distribution of chemokines or other signaling molecules.
