HG Boman, DA Monner - Journal of Bacteriology, 1975 - Am Soc Microbiol

Chemical analyses of the carbohydrate composition of lipopolysaccharides (LPS) from a number of LPS mutants were used to propose a schematic composition for the LPS from Escherichia coli K-12. The formula contains four regions: the first consists of lipid...

… coli K-12, a bisphosphorylated lipid A precursor molecule with two amide and two ester-bound (R)-3-hydroxymyristate residues (lipid IV A ) is synthesized from … coli K-12, which catalyze the latter enzyme reactions using acyl carrier protein-activated fatty acids...

Distinct Effects of Monophosphoryl Lipid A, Oligodeoxynucleotide CpG, and Combination Adjuvants on Modulating Innate and Adaptive Immune Responses to Influenza Vaccination.

Immune network

Ko EJ, Lee YT, Lee Y, Kim KH, Kang SM.
PMID: 29093654
Immune Netw. 2017 Oct;17(5):326-342. doi: 10.4110/in.2017.17.5.326. Epub 2017 Oct 19.

Monophosphoryl lipid A (MPL) and oligodeoxynucleotide CpG are toll-like receptor (TLR) 4 and 9 agonist, respectively. Here, we investigated the effects of MPL, CpG, and combination adjuvants on stimulating

Mechanisms of polymyxin resistance: acquired and intrinsic resistance in bacteria.

PMID: 25505462
Front Microbiol. 2014 Nov 26;5:643. doi: 10.3389/fmicb.2014.00643. eCollection 2014.

Polymyxins are polycationic antimicrobial peptides that are currently the last-resort antibiotics for the treatment of multidrug-resistant, Gram-negative bacterial infections. The reintroduction of polymyxins for antimicrobial therapy has been followed by an increase in reports of resistance among Gram-negative bacteria....

The Effect of Temperature, Cations, and Number of Acyl Chains on the Lamellar to Non-Lamellar Transition in Lipid-A Membranes: A Microscopic View.

Journal of chemical theory and computation

Pontes FJ, Rusu VH, Soares TA, Lins RD.

J Chem Theory Comput. 2012 Oct 09;8(10):3830-8. doi: 10.1021/ct300084v. Epub 2012 Jun 05.

Lipopolysaccharides (LPS) are the main constituent of the outer bacterial membrane of Gram-negative bacteria. Lipid-A is the structural region of LPS that interacts with the innate immune system and induces inflammatory responses. It is formed by a phosphorylated β-d-glucosaminyl-(1→6)-α-N-glucosamine...

Myocardial tissue appears to possess an endogenous protective mechanism whereby brief ischemic periods precondition cells to better withstand both reversible and irreversible injury associated with prolonged subsequent ischemic events. Protection develops within minutes of transient ischemia, dissipates within 1-2...
