Prenatal infection predisposes offspring to enhanced susceptibility to imiquimod-mediated psoriasiform dermatitis in mice

open access: yesDermatologica Sinica, 2022
Background: Infection can upregulate T helper 17 (Th17) signaling and exacerbate psoriasis. Literature has indicated that prenatal infection induces embryonic development toward Th17 signaling and is a risk factor for developing certain Th17-skewing ...

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

A Novel Lipopolysaccharide Recognition Mechanism Mediated by Internalization in Teleost Macrophages

open access: yesFrontiers in Immunology, 2018
Macrophages in teleosts are less sensitive to lipopolysaccharide (LPS) compared to mammals. The functional equivalent of the mammalian LPS surface receptor in teleost macrophages for the pro-inflammatory response is either non-existent or replaced by ...

Chimeric diphtheria toxin–CCL8 cytotoxic peptide for breast cancer management

open access: yesMolecular Oncology, EarlyView.
DTCCL8 is a recombinant fusion toxin that targets cancer cells expressing chemokine receptors. By combining diphtheria toxin with CCL8, DTCCL8 binds to multiple receptors on tumor cells and induces selective cytotoxicity. This strategy enables receptor‐mediated targeting of cancer and may support the development of chemokine‐guided therapeutics ...

Peripheral Immune Activation in Mice Elicits Unfolded Protein Responses Independent on MyD88 Pathway in the Liver but not the Hypothalamus and Hippocampus

open access: yesFrontiers in Physiology, 2022
Neuroimmune interactions between the immune system and CNS as well as peripheral organs such as the liver play a key role in the pathophysiological state of diseases.

Microglia limit brain tumor development by restricting tumor cell proliferation and inducing T‐cell immunity

open access: yesMolecular Oncology, EarlyView.
Microglia (BV2) and IL‐4‐treated BMDMs promote astrocytoma clustering and inhibit tumor growth, not shown in other macrophage cells. In vivo, microglial co‐implantation enhances CD8+ T cell infiltration, elevates Granzyme B, lowers circulating MDSCs, and extends survival only in immune‐competent mice, but not in immune‐deficient mice.

Investigation of the optimal dose for experimental lipopolysaccharide-induced recognition memory impairment: behavioral and histological studies

open access: yesJournal of Integrative Neuroscience, 2022
Background: Lipopolysaccharide (LPS) administration is one of the most commonly used methods for inducing inflammation in animal models. Several animal studies have investigated the effects of acute and chronic peripheral administration of LPS on ...

Function and Biogenesis of Lipopolysaccharides [PDF]

open access: yesEcoSal Plus, 2018
The cell envelope is the first line of defense between a bacterium and the world-at-large. Often, the initial steps that determine the outcome of chemical warfare, bacteriophage infections, and battles with other bacteria or the immune system greatly depend on the structure and composition of the bacterial cell surface.

Protein O‐glycosylation in the Bacteroidota phylum

open access: yesFEBS Open Bio, EarlyView.
Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

D-galactan II is an immunodominant antigen in O1 lipopolysaccharide and affects virulence in Klebsiella pneumoniae: implication in vaccine design

open access: yesFrontiers in Microbiology, 2014
In the O1 strain of Klebsiella, the lipopolysaccharide (LPS) O-antigen is composed of D-galactan I and D-galactan II. Although the composition of the O1 antigen of Klebsiella was resolved more than two decades, the genetic locus involved in the ...
