  <dc:description xml:lang="srp">Značajno slabije izražen primarni bilijarni holangitis izazvan infekcijom bakterijom Novosphingobium aromaticivorans, sa manjim oštećenjem bilijarnih kanalića i vrlo slabo izraženom fibrozom, detektovan je u grupama Lgals3−/− i miševa tretiranih inhibitorom galektina-3, GM-CT-01. U jetrama wild type miševa inficiranih bakterijom Novosphingobium aromaticivorans detektovana je veća zastupljenost inflamacijskih makrofaga, NK, NKT i T ćelija u infiltratima. U infiltratima jetre Lgals3-/- i miševa tretiranih inhibitorom galektina-3, GM-CT-01, je nakon infekcije
bakterijom Novosphingobium aromaticivorans, u infiltratima jetre zabeležena manja
ekspresija inflamazoma NLRP3 i manja produkcija IL-1β u poređenju sa grupom wild type
miševa. In vitro stimulacija wild type peritonealnih makrofaga bakterijom
Novosphingobium aromaticivorans za posledicu ima veću ekspresiju NLRP3, aktivnost
kaspaze-1 i produkciju IL-1β u poređenju sa stimulisanim peritonealnim makrofagima
Lgals3−/− miševa. GM-CT-01 takođe redukuje aktivaciju DC i ekspresiju citokina IL-4,
IL-1β i p40, zajedničke subjedinice IL-12 i IL-23 u DC in vitro stimulisanim bakterijom
Novosphingobium aromaticivorans.
Naši rezultati ukazuju na značaj galetkina-3 u stimulaciji inflamacije u RVS
izazvanom infekcijom bakterijom Novosphingobium aromaticivorans, a koji se ogleda u
aktivaciji DC i inflamazoma NLRP3 i posledičnoj produkciji IL-1β, i ukazuju da
galektin-3 može da bude meta delovanja potencijalnih novih lekova. Galektin-3 je
verovatno uključen u inflamacijski odgovor na komensalne bakterije creva što može da
bude incijalni okidač za razvoj primarnog bilijarnog holangitisa.</dc:description>
  <dc:description xml:lang="eng">Marked attenuation of primary biliary cholangitis (PBC), manifested by the absence of bile duct damage and fibrosis, is detected in Lgals3−/− and Galectin-3 inhibitor, GM-CT-01, treated mice. Liver infiltrates of Novosphingobium aromaticivorans infected wild type mice had higher incidence of pro-inflammatory macrophages, NK, NKT, and T cells. Lgals3
deletion and treatment with Galectin-3 inhibitor, GM-CT-01, reduced liver damage and fibrosis, inflammatory mononuclear cell infiltrate, expression of NLRP3 inflammasome in the
liver infiltrates and interleukin-1β (IL-1β) production in the livers of Novosphingobium
aromaticivorans infected mice. In vitro stimulation of wild type peritoneal macrophages with
Novosphingobium aromaticivorans caused increased NLRP3 expression, caspase-1 activity
and IL-1β production, compared with Lgals3−/− cells. GM-CT-01 reduced activation of
dendritic cells and expression of IL-4, IL-1β, and p40, common subunit of IL-12 and IL-23 in
dendritic cells in vitro stimulated with Novosphingobium aromaticivorans. Our data highlight
the importance of Galectin-3 in promotion of inflammation in Novosphingobium
aromaticivorans induced PBC by enhancing the activation of dendritic cells and NLRP3
inflammasome leading to enhanced production of IL-1β, and indicate Galectin-3 as possible
therapeutical target in autoimmune cholangitis. Galectin-3 appears involved in inflammatory
response to gut commensals leading to PBC.</dc:description>
