Wang H, Germanson TP, Guyenet PG (2002) Depressor and tachypneic responses to chemical stimulation of the ventral respiratory group are reduced by ablation of neurokinin-1 receptor-expressing neurons. J Neurosci 22(9):3755-3764. doi: 10.1523/JNEUROSCI.22-09-03755.2002
Summary: The pre-Bötzinger complex is a region of the ventral respiratory group (VRG) in the brain. Injection of excitatory amino acids into this region can cause a variety of responses such as rapid breathing, hypotension, and elevated arterial pressure. The authors used SSP-SAP (Cat. #IT-11) to eliminate the neurokinin-1 receptor (NK-1r) positive neurons in the VRG to determine their role in control of respiration and arterial pressure. Intraparenchymal injection of 0.313 ng/50 nl SSP-SAP produced several abnormal respiratory effects in rats treated with excitatory amino acids. The results indicate that NK-1r positive neurons in the ventrolateral medulla play an important role in respiratory rhythm and blood pressure.
