Distribution of neurokinin-2 receptors in the guinea-pig gastrointestinal tract


The distribution of neurokinin-2 (NK2) tachykinin receptors was investigated by immunohistochemistry in the guinea-pig oesophagus, stomach, small and large intestine. Receptor immunoreactivity occurred at the surfaces of smooth muscle cells throughout the digestive tract. Nerve fibre varicosities in enteric ganglia were also immunoreactive. In myenteric… (More)
