The recognition and elimination of invading pathogens are vital for host survival. Macrophages play a central role in protection cells functionally reminiscent vertebrate macrophages present all multicellular organisms. A pattern responsible bacterial found on the surface is CD14. These possess repertoire antimicrobial molecules stored their granules lysosomes. Polarization states observed mamm...

Hanani, M., M. Francke, W. Härtig, J. Grosche, A. Reichenbach, and T. Pannicke. Patch-clamp study of neurons and glial cells in isolated myenteric ganglia. Am J Physiol Gastrointest Liver Physiol 278: G644–G651, 2000.— Most of the physiological information on the enteric nervous system has been obtained from studies on preparations of the myenteric ganglia attached to the longitudinal muscle la...

BACKGROUND The enteric glia network may be involved in the pathogenesis of inflammatory bowel disease (IBD). Enteric glia cells (EGCs) are the major source of glial-derived neurotrophic factor (GDNF), which regulates apoptosis of enterocytes. The aim of the study was to determine the distribution of EGCs and GDNF during gut inflammation and to elucidate a possible diminished enteric glia networ...

Mutations in the RET gene are the primary cause of Hirschsprung disease (HSCR), or congenital intestinal aganglionosis. However, how RET malfunction leads to HSCR is not known. It has recently been shown that glial cell line-derived neurotrophic factor (GDNF) family receptor alpha1 (GFRalpha1), which binds to GDNF and activates RET, is essential for the survival of enteric neurons. In this stud...

Cultures of dissociated foetal and postnatal mouse gut gave rise to neurosphere-like bodies, which contained large numbers of mature neurons and glial cells. In addition to differentiated cells, neurosphere-like bodies included proliferating progenitors which, when cultured at clonal densities, gave rise to colonies containing many of the neuronal subtypes and glial cells present in the mammali...

Although recent studies have shown that enteric neurons control intestinal barrier function, the role of enteric glial cells (EGCs) in this control remains unknown. Therefore, our goal was to characterize the role of EGCs in the control of intestinal epithelial cell proliferation using an in vivo transgenic and an in vitro coculture model. Assessment of intestinal epithelial cell proliferation ...

BACKGROUND Recent works provide evidence of the importance of the prostaglandin D2 (PGD2) metabolic pathway in inflammatory bowel diseases. We investigated the expression of PGD2 metabolic pathway actors in Crohn's disease (CD) and the ability of the enteric nervous system (ENS) to produce PGD2 in inflammatory conditions. METHODS Expression of key actors involved in the PGD2 metabolic pathway...

Calcineurin (CaN) is a Ca2+/calmodulin (Ca2+/CaM)-dependent serine/threonine protein phosphatase expressed in most mammalian tissues but found at higher concentration in brain. In the last decade there have been a steadily increasing number of studies identifying neuronal CaN as a primary suspect in neuronal vulnerability, synapse loss, dendritic atrophy, synaptic dysfunction and neuroinflammat...
