The present study has used capsaicin-induced neuropeptide depletion to examine the role of neurogenic inflammation in the development of edema and functional deficits following traumatic brain injury (TBI). Adult, male rats were treated with capsaicin (neuropeptide-depleted) or equal volume vehicle
BACKGROUND
Increased intracranial pressure induces neurogenic pulmonary edema (NPE), potentially explaining why only lungs from less than 20% of brain dead organ donors can be used for transplantation. This study investigated the underlying mechanisms of NPE, focusing on neuropeptides, which
Substance P is involved in nociception in both the peripheral nervous system and the CNS and has been documented to play a crucial role in the complex regional pain syndrome (CRPS). So far, however, most experimental animal models are restricted to the effect of neurokinin-1 receptor blockers to
Neurogenic inflammation and innate immunity may work together to protect mucosal surfaces, including the ocular surface. When the eye is exposed to pathogens, chemical irritants, or mechanical disruption, neurogenic inflammation is produced through release of neuromodulators, such as substance P and
Pain, edema, increased skin temperature, reddening and trophic changes characterize complex regional pain syndrome (CRPS). Recently, we have been able to show facilitated neurogenic inflammation on the affected limb. In the current study unaffected limbs were examined after resolution of the CRPS
The complex regional pain syndrome (CRPS) is characterized by enhanced neurogenic inflammation, mediated by neuropeptides. Neutral endopeptidase (NEP) is a key enzyme in neuropeptide catabolism. We used NEP knock out (ko) mice to investigate whether NEP deficiency leads to increased pain behavior
We have earlier shown that PACAP-38 decreases neurogenic inflammation. However, there were no data on its receptorial mechanism and the involvement of its PAC1 and VPAC1/2 receptors (PAC1R, VPAC1/2R) in this inhibitory effect. Neurogenic inflammation in the mouse ear was induced by topical
Neurogenic inflammation frequently causes acute plasma leakage in airways and life-threatening pulmonary edema. However, limited strategies are available to alleviate neurogenic inflammation. Proopiomelanocortin (POMC) is the precursor of anti-inflammatory melanocortins, which have been proposed of
Aims: Investigate the involvement of the histaminergic projections from tuberomammillary nucleus (TMN) to the spinal cord in the modulation of nociception and peripheral edema in a model of monoarthritis.
Brain edema and swelling is a critical factor in the high mortality and morbidity associated with traumatic brain injury (TBI). Despite this, the mechanisms associated with its development are poorly understood and interventions have not changed in over 30 years. Although neuropeptides and
The beta 2-adrenergic agonist formoterol has been shown to inhibit plasma extravasation in the respiratory mucosa associated with neurogenic inflammation as well as that caused by histamine or bradykinin. It is unknown whether these effects of formoterol are mediated through an action of sensory
The etiology of shoulder-hand syndrome is as yet unknown. We hypothesized that it may be due to damaged unmyelinated fibers in front of the subscapular muscle. We examined the existence of edema and hypersensitivity to pain in the hands of stroke patients during the subacute stage and their
Each year, 15 million people suffer a stroke, of which 5 million die and 5 million are left permanently disabled. Cerebral swelling is of particular concern following stroke as it accounts for much of the death and disability. However, the mechanisms leading to cerebral swelling are not yet fully

Although clinical spinal cord injury (SCI) occurs within a closed environment, most experimental models of SCI create an open injury. Such an open environment precludes the measurement of intrathecal pressure (ITP), whose increase after SCI has been linked to the development of greater tissue damage
