Key Concepts

Basophils

Basophils are a type of white blood cell that play a key role in the innate immune system. They are known for releasing histamine and other mediators during inflammatory and allergic reactions, which serve to increase blood vessel permeability and attract other immune cells to the site of infection or injury.

Histamine Secretion

Histamine is a biochemical substance released mainly by basophils and mast cells. It is essential in the body’s inflammatory response, as it helps to dilate blood vessels and increases their permeability, thereby facilitating the rapid mobilization of immune cells to address potential threats such as pathogens or allergens.

Immune Cell Functions

The immune system is composed of various cells, each with specialized functions such as antibody production, direct cell-mediated cytotoxicity, and the release of inflammatory mediators. Understanding the distinct roles of these cells, including their mechanisms like phagocytosis, cytokine secretion, and antigen recognition, is crucial to grasping how the body defends itself against diseases.
