Cell-Mediated Immunity · Pathology

Granuloma formation in tuberculosis is primarily mediated by:

  1. Antibody-mediated pathogen neutralization
  2. Complement-mediated cell lysis
  3. Th1-mediated macrophage activation
  4. IgE-mediated mast cell degranulation
Show answer and explanation

Correct answer: Th1-mediated macrophage activation

Granulomas form due to Th1-mediated activation of macrophages via IFN-γ. This response attempts to contain persistent pathogens.
