Identification of the abundant neuropeptide from abdominal perisympathetic organs of locusts.

abstract：:Food deprivation and adrenalectomy are associated with low concentrations of leptin in blood and the absence of obesity. Because leptin is known to cross the blood-brain barrier (BBB) by a saturable transport system, we examined whether fasting and adrenalectomy (ADX) also act at the BBB. Multiple-time regression anal...
