20TT in the heat increased I-FABP and elevated inflammatory cytokines (IL-6 and TNF-α) compared to pre-exercise values but did not result in endotoxemia.
The α7 nAChR partial agonist GTS-21 reduces secretion of pro-inflammatory cytokines including interleukin-6 (IL6) and tumor-necrosis factor (TNF) in models of endotoxemia and sepsis, and its anti-inflammatory effects are widely ascribed to α7 nAChR activation.
LAH also significantly reduced the concentration of tumour cell necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in both serum and colon and decreased the level of lipopolysaccharides (LPS) in serum and feces, leading to reduced systematic inflammation and metabolic endotoxemia.

The inhalation of sevoflurane inhibited increases in myeloperoxidase (MPO), macrophage inflammatory protein-2 (MIP-2), TNF-α, and IL-1β levels (P < 0.05) induced by endotoxemia, whereas IL-6 release was facilitated.
Selective stimulation of acetylcholine action on the M1 muscarinic acetylcholine receptor (M1 mAChR) by central administration of the positive allosteric modulator benzyl quinolone carboxylic acid (BQCA) suppressed serum TNF (TNFα) levels in murine endotoxemia.
20TT in the heat increased I-FABP and elevated inflammatory cytokines (IL-6 and TNF-α) compared to pre-exercise values but did not result in endotoxemia.
Moreover, the expression of TNF-α and IFN-γ in the splenocytes was significantly downregulated along with improving host survival against the LPS-induced lethal endotoxemia in the same way.
In LPS-stimulated RAW264.7 cells and in peritoneal macrophages from endotoxemic mice, NC and TOP1 inhibitors significantly enhanced the activation of Akt, a critical signal transducer for IL-10 production, and inhibition of Akt prevented these compounds from enhancing IL-10 production and ameliorating endotoxemia.
In vivo, levels of IL-1β, IL-6, and TNFα in the lungs and liver were markedly reduced during endotoxemia in IL-37Tg mice but not observed in IL-37D20ATg mice.
This study investigated (i) the nicotine modulation of hemodynamic and renal vasodilatory responses to endotoxemia in rats, and (ii) roles of α7 or α4β2-nAChRs and related HSP70/TNFα/iNOS signaling in the interaction.
Male C57BL/6 mice with or without endotoxaemia were exposed to MV (10 mL/kg) for 8 hours after administrating either 100 mg/kg of EP or 100 mg/kg of anti-HMGB1 antibody.
In a LPS-induced endotoxemia mouse model, a single intraperitoneal injection of Cl-EE (75-300 mg/kg) could lower circulatory TNF-α, IL-6 and MCP-1 levels.
Pro-Inflammatory Th1 and Th17 Cells Are Suppressed During Human Experimental Endotoxemia Whereas Anti-Inflammatory IL-10 Producing T-Cells Are Unaffected.
We hypothesize (I) PD-driven endotoxemia may increase the host responsiveness to autoantigens via TLR4 activation and (II) this participates in development and propagation of RA (III) circulating PD-derived bacterial DNA is taken up by phagocytes, activates TLR9, and thus increases the responsiveness to autoantigens.
MV with endotoxemia aggravated VIDD, as demonstrated by the increases in the expression levels of TLR4, caspase-3, atrogin-1, muscle ring finger-1, and microtubule-associated protein light chain 3-II.
One potential mechanism is via gut microbiota derived bacterial lipopolysaccharide (LPS) entering into the circulation and activation of Toll-like receptor-4.This is called metabolic endotoxemia.
Further, Adrb2<sup>-</sup><sup>/</sup><sup>-</sup> animals rapidly succumbed to endotoxemia in response to a sub-lethal LPS challenge and exhibited elevated serum levels of TNF-α and reduced IL-10.
It alleviated tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in activated macrophages by downregulating the NF-κB activity, and it reduced the mortality rate in LPS induced endotoxemia mice.

Here, we (1) determine whether oral gavage of LPS, as a model of gut-derived endotoxemia, affects anxiety-like and/or repetitive behaviors; (2) test whether these changes depend on TLR4 signaling; and (3) test the extent to which gut-derived endotoxin and TLR4 antagonism affects males and females differently.
