If a previously healthy individual develops acquired antibody deficiency after prolonged exposure to a specific environmental toxin that selectively destroys plasma cells, which consequence follows?

💡 Explanation

Increased susceptibility to infections arises because antibody deficiency impairs the humoral immune response, therefore the ability to neutralize pathogens and prevent their entry into cells is lost, rather than enhanced T-cell activity or reduced inflammation which depend on different immune pathways.

• An individual with presbyopia attempts to read a book. Which mechanism explains why the image appears blurry, even when the ciliary muscles contract to accommodate near vision?
• Why does chronic inflammation, triggered by persistent exposure to inhaled silica particles, lead to sustained activation of the NF-κB pathway in lung epithelial cells?
• A patient with thrombocytosis (excess platelets) experiences increased risk of vascular occlusion. Why does platelet aggregation cause this heightened occlusion risk?
• Why does intense, prolonged exposure to jet engine noise potentially lead to permanent hearing loss?
• If a child with chronic kidney disease doesn't receive sufficient vitamin D supplementation, which consequence is most likely related to renal osteodystrophy?
• Why does vasoconstriction in peripheral blood vessels lead to shivering during thermoregulation when a person enters a walk-in freezer?
