Question

Which cells are responsible for allergic responses through the release of vasoactive amines from their cytoplasmic granules?

a) Basophils and mast cells
b) Dendritic cells
c) Lymphocytes
d) Monocytes
e) Neutrophils

Answer 1

Basophils and mast cells are responsible for allergic responses through the release of vasoactive amines from their cytoplasmic granules.

Step-by-step explanation:

The cells responsible for allergic responses through the release of vasoactive amines from their cytoplasmic granules are basophils and mast cells. Basophils are non-phagocytic leukocytes that release histamines to dilate blood vessels and increase permeability during inflammation. Mast cells are leukocytes that produce inflammatory molecules, including histamine, in response to large pathogens. They are also involved in allergy and hypersensitivity responses.
