Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Helper T-lymphocytes
Concept:

HIV exhibits strict cellular tropism mediated by the CD4 surface receptor.

Solution:

  • The main target of HIV is the Helper T-lymphocytes (CD4+ cells), which serve as the "command centers" of the immune system.
  • The destruction of these cells leads to the catastrophic immune failure seen in AIDS.


Why other options are incorrect:

  • Red blood cells, B-lymphocytes, Liver cells: Do not express the required CD4 receptor necessary for primary HIV attachment and entry.

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.
