Quizplus · Accepted Answer

Mast cells and histamines are known to initiate inflammatory responses. When tissue is damaged or infected, mast cells release histamines which trigger vasodilation and increased permeability of blood vessels, leading to the accumulation of fluid and immune cells at the site of injury or infection. This process helps to remove harmful pathogens and promote tissue healing. While phagocytes and dendritic cells are important immune cells involved in the inflammatory response, they are not the cells that initiate it. Similarly, lymphocytes and interferons are involved in the adaptive immune response, not the initial inflammatory response.
