Due to the acid conditions of the bacterium living habitat, uncommon structural features composing its cell envelope are expected. In the present work we have investigated the A. pasteurianus CIP103108 lipopolysaccharide (LPS) structure and immunoactivity. The structure of the lipid A and of two different O-polysaccharides was assessed. Furthermore, immunological studies with human cells showed a low immunostimulant activity of the isolated LPS, in addition to a slight capability to lower the NF-kappa B activation upon stimulation by toxic LPS. specialized Lipopolysaccharides (LPS) Gram-negative bacteria Innate immunity MD2-TLR4 Acetobacter pasteurianuss 084 050 020 119 1027-1035 2018 0141-8130 https://www.documentation.ird.fr/hor/fdi:010074166 10.1016/j.ijbiomac.2018.08.035 0141-8130 [F B010074166] https://www.documentation.ird.fr/hor/fdi:010074166 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-11/010074166.pdf IRD - Base Horizon / Pleins textes 2018-12-06 2023-07-11 fdi:010074166 fre
