Histamine Causes Which of the Following

Question

Histamine causes which of the following?
A) TLR production
B) increased permeability and dilation of blood vessels
C) antibody production
D) complement protein production
E) the anti-inflammatory response

Accepted Answer

Histamine is a chemical mediator released by mast cells and basophils during an immune response, and one of its main functions is to cause increased permeability and dilation of blood vessels. This can result in the characteristic symptoms of inflammation, including redness, swelling and warmth. Histamine does not cause TLR production, antibody production, complement protein production or the anti-inflammatory response.
