Neuroimmuno-modulation in gastric mucosa

Abstract

Számos neuropeptidről feltételezik, hogy részt vesz a gyomornyálkahártya védelmében és szerepet játszik a krónikus gastritis kialakításában.Célkitűzés:Arra kerestünk választ, hogy van-e morfológiai kapcsolat az idegrostok és az immunkompetens sejtek között, termelnek-e az immunsejtek is neuropeptideket, valamint létezik-e kolokalizáció TNF-α-val és NF-κ-B-vel.Módszer:Immunhisztokémiai, konfokális lézer- és elektronmikroszkóppal vizsgáltuk az idegrostokat és immunkompetens sejteket ép és gastritises nyálkahártyában.Eredmények:Gyulladás hatására a neuropeptid-tartalmú idegrostok száma szignifikánsan megemelkedett. Az ép gyomornyálkahártyában a lymphocyták, plazmasejtek, hízósejtek mennyisége alacsony és soha sem mutatott immunfestést ezen neuropeptid-ellenanyagokra. Azonban gastritisben az immunkompetens sejtek egy része SP- és NPY-immunreaktivitást mutatott. Ezen sejtekben az SP kolokalizációban fordult elő a TNF-α-val és NF-κ-B-vel. Az immunsejtek és a jelzett idegrostok közötti távolság 1 µm vagy ennél is kevesebb volt.Következtetések:Az idegrostokból és az immunkompetens sejtekből felszabaduló mediátorok részt vesznek a neurogén gyulladás kialakulásában, a krónikus gastritis fenntartásában.
