Answer: the mast cells and basophils.

Explanation: mast cells are the histamine secreting cells of the body. Histamine act to as a defense system by triggering a reaction to combat the effect of the allergy, thereby leading to inflammation, sneezing and other allergy symptoms ... Basophils, a type of white blood cell also secrete histamine and are also responsible for some inflamatory reactions as a way of immune response.
