The connective tissue-dwelling cells that resemble basophils and release histamine in association with allergic reactions are called mast cells.

Mast cells are a type of immune cell that play a crucial role in the body's response to allergens. They are found in various tissues throughout the body, especially in areas that are prone to allergy, such as the skin, lungs, and digestive tract. When an allergen enters the body, mast cells can degranulate, releasing various substances, including histamine. Histamine is a chemical that contributes to inflammation and the typical symptoms associated with allergic reactions such as itching, swelling, and redness. Beyond their role in allergies, mast cells also participate in defense against pathogens and play a role in wound healing. Their function highlights the complexity of the immune system and the delicate balance required to protect the body without overreacting to non-threatening substances.
