Anaphylaxis can result from a bee sting due to a complex IgE-mediated hypersensitivity. If an individual with this sensitivity is stung, which consequence is most likely?

💡 Explanation

Anaphylaxis involves mast cell degranulation and histamine release triggered by IgE antibody binding to the bee venom allergen. Because histamine induces systemic vasodilation, increased vascular permeability, and bronchoconstriction, therefore the most likely consequence is systemic vasodilation and bronchoconstriction, rather than localized T-cell activation or IgG production.

• If a patient with chronic anemia experiences a sudden decrease in 2,3-BPG levels, which consequence follows regarding oxygen transport?
• Why does excessive mechanical loading during intense weightlifting eventually lead to stress fractures in bone undergoing remodeling?
• During vigorous exercise, which mechanism ensures sufficient muscle oxygenation, overriding local blood pressure?
• Why does maladaptive vasodilation occur during septic shock, compromising thermoregulation?
• If an individual repeatedly uses an addictive substance, which consequence results in the mesolimbic pathway?
• If a patient with chronic neuropathic pain receives a dorsal column stimulator implant, which mechanism explains the pain reduction they experience?
