Mаny sensоry neurоns express different kinds оf neurotrаnsmitter receptors thаt are used to modulate sensory activity based on neural inputs. In addition to odor receptors located on their dendrites, olfactory neurons in the nasal cavity possess adrenergic receptors. Experiments have shown that applying norepinephrine, a main adrenergic neurotransmitter, to isolated olfactory neurons inhibits their responses to odors. Applying norepinephrine alone, without odors, does not affect olfactory neurons. Actions of norepinephrine (noradrenaline) on olfactory neurons in the presence and absence of odors. In autoimmune diseases, antibodies can sometimes be generated against neurotransmitter receptors. Depending on the extracellular region of the receptor to which the antibody binds, the receptor can be stimulated or inhibited. Autoantibodies against neurotransmitter receptors may activate or inhibit them. You wish to determine whether antibodies that stimulate the adrenergic receptors in other systems will also stimulate the adrenergic receptors on olfactory neurons, thus inhibiting their responses to odors. You isolate olfactory neurons from mice, place them into nutrient-rich medium in a dish, and record responses from them. You observe that antibodies that have been previously shown to stimulate the adrenergic receptor inhibit the neuron's responses to odors. However, when you inject these same antibodies into a mouse's vascular system and test the animal responses to odors, there is no effect.
