Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: Macrophages
Concept: Host cell susceptibility to HIV.

Solution: Macrophages (and their precursor monocytes) express surface CD4 molecules alongside CCR5 co-receptors, making them major targets and persistent tissue reservoirs for HIV.

Why other options are incorrect:
  • Option A, Option B & Option C: Granulocytes lack the necessary receptor/co-receptor combination (CD4/CCR5) required for productive HIV infection.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
