Function of lipopolysaccharide (LPS)-binding protein (LBP) and CD14, the receptor for LPS/LBP complexes: a short review. Schumann RR. Res Immunol, 143(1):11-15, 01 Jan 1992 Cited by: 68 articles | PMID: 1373512. Review

BBB disruption under pathological conditions such as neurodegenerative disease and inflammation is observed in parallel with microglial activation. To test whether activation of microglia is linked to BBB dysfunction, we evaluated the effect of lipopolysaccharide (LPS Most serovars of Salmonella also possess a lipopolysaccharide with a complex O-antigen (OAg) structure. The number of OAg units attached to the core polysaccharide varies between 16 and more than 100 repeats, with a trimodal distribution. This work investigated the correlation of the OAg length with the functions of the SPI1-T3SS and the SPI2-T3SS. The main mechanism consists of direct competition between the antagonistic lipopolysaccharides and E. coli lipopolysaccharide for the same binding site on hMD‐2, while the secondary mechanism involves the ability of antagonistic lipopolysaccharide–hMD‐2 complexes to inhibit E. coli lipopolysaccharide–hMD‐2 complexes function at hTLR4. Our objective was to investigate the effect of gram-negative bacterial infection on the ovaries and serum level of P4 and 17β-E2 during the preimplantation days of pregnancy in the mouse. We found that lipopolysaccharide alters the serum level of P4 and E2 during the preimplantation days of pregnancy and elevates the E2/P4 ratio, which may keep the uterus nonreceptive during the mTOR‐mediated metabolic reprogramming shapes distinct microglia functions in response to lipopolysaccharide and ATP Yaling Hu Neuroscience Research Center and Department of Neurology of Second Affiliated Hospital, Key Laboratory of Medical Neurobiology of Zhejiang Province, Zhejiang University School of Medicine, Hangzhou, China 2020-08-17 · Lipopolysaccharid Lipopolysaccharid von Salmonella typhimurium: I Lipoid A-Region mit phosphorylierten (P in Kreis = Phosphat) Glucosamin-(GlcN-)Disacchariden, verestert mit langkettigen Fettsäuren (~, 12–16 C-Atome); dieser innere LPS-Abschnitt bildet die äußere Schicht der Lipiddoppelschicht der äußeren Zellwandmembran (Bakterienzellwand).
