The aim of this paper is to present the state of knowledge on cutaneous neurogenic inflammation. Peripheral effector functions served by afferent sensory neurons underlie the so-called neurogenic inflammation. The mechanism of cutaneous neurogenic inflammation is connected with the release of neuropeptides from the sensory endings. They also exert a number of functions within the immune system....

Neuropeptides play an important role in the regulation of feeding behavior and obesity. The mechanisms for controlling food intake involve a complicated interplay between peripheral systems (including gustatory stimulation, gastrointestinal peptide secretion, and vagal afferent nerve responses) and central nervous system (CNS) neuropeptides and/or monoamines. These neuronal systems include neur...

The measure of neuropeptides is an important tool in biology to better define endocrine and neuroendocrine function. Traditionally most methods have relied on the development of specific antibodies. Newer molecular methodologies have used measures of gene expression of neuropeptide precursors, such as Northern blot, PCR or in situ hybridization analysis. Matrix-assisted laser desorption/ionizat...

Neuropeptides play a variety of roles in many physiological processes and serve as potential therapeutic targets for the treatment of some nervous-system disorders. In recent years, there has been a tremendous increase in the number of identified neuropeptides. Therefore, we have developed NeuroPep, a comprehensive resource of neuropeptides, which holds 5949 non-redundant neuropeptide entries o...

Inflammatory bowel disease (IBD) is a chronic, relapsing condition involving complex interactions between genes and the environment. The mechanisms triggering the initial attack and relapses, however, are not well understood. In the past several years the enteric nervous system (ENS) has been implicated in the pathophysiology of IBD. Both the ENS and the central nervous system (CNS) can amplify...

Animal behaviour often comprises spatially separated sub-reactions and even ciliated larvae are able to coordinate sub-reactions of complex behaviours (metamorphosis, feeding). How these sub-reactions are coordinated is currently not well understood. Neuropeptides are potential candidates for triggering larval behaviour. However, although their immunoreactivity has been widely analysed, their f...

Affiliative social relationships (e.g., among spouses, family members, and friends) play an essential role in human society. These relationships affect psychological, physiological, and behavioral functions. As positive and enduring bonds are critical for the overall well-being of humans, it is not surprising that considerable effort has been made to study the neurobiological mechanisms that un...

One of the important developments during the neuroendocrine period from 1955 to 1973 was the emergence of a new, unique research area: systematic studies of the actions of peptides on the central nervous system, including psychotropic and behavioral effects. During this period, the studies were concerned primarily with substance P, bradykinin, angiotensin,ACTH,MSH, and vasopressin. Studies on s...

Pulmonary neuroendocrine cells exhibit highly specialized differentiation with a neurosecretory phenotype and significant bioactive peptide hormone content. In addition to these functions, pulmonary neuroendocrine cells have been demonstrated to act as chemoreceptors for hypoxia (1). Specific pulmonary disorders, including bronchopulmonary dysplasia, bronchiectasis, cystic fibrosis, pulmonary h...

The SALMFamides are a family of neuropeptides that act as muscle relaxants in echinoderms. Two types of SALMFamides have been identified: L-type (e.g. the starfish neuropeptides S1 and S2) with the C-terminal motif LxFamide (x is variable) and F-type with the C-terminal motif FxFamide. In the sea urchin Strongylocentrotus purpuratus (class Echinoidea) there are two SALMFamide genes, one encodin...
