Intrinsic Cardiac Adrenergic Cells Contribute to LPS-Induced Myocardial Dysfunction

Researchers showed that norepinephrine secretion from intrinsic cardiac adrenergic cells was increased through activation of Toll-like receptor 4 to aggravate myocardial TNF-α production and dysfunction by lipopolysaccharide (LPS).

Chemokine CCL18 Promotes Phagocytosis Through Its Receptor CCR8 Rather than PITPNM3 in Human Microglial Cells

Investigators showed that CCL18 did not change the expression of the inflammatory factors, interleukin (IL)-1β, IL-6, tumor necrosis factor alpha, or inducible nitric oxide synthase, but significantly induced expression of the macrophage markers, MRC-1 and ARG-1 M2, in a human microglial clone 3 cell line

Inhalation of Dimethyl Fumarate-Encapsulated Solid Lipid Nanoparticles Attenuate Clinical Signs of Experimental Autoimmune Encephalomyelitis and Pulmonary Inflammatory Dysfunction in Mice

Scientists investigated the potential effects of solid lipid nanoparticles containing dimethyl fumarate, administered by inhalation on the clinical signs, central nervous system inflammatory response, and lung function changes in mice with experimental autoimmune encephalomyelitis.

LncRNA MEG3 Ameliorates NiO Nanoparticles-Induced Pulmonary Inflammatory Damage via Suppressing the p38 Mitogen Activated Protein Kinases Pathway

Wistar rats were treated with nickel oxide nanoparticles (NiO NPs) suspensions by intratracheal instillation twice-weekly for nine weeks. A549 cells were treated with NiO NPs suspensions for 24 hour.

Polygonatum sibiricum Polysaccharides (PSP) Improve the Palmitic Acid (PA)-Induced Inhibition of Survival, Inflammation, and Glucose Uptake in Skeletal Muscle Cells

The underlying molecular mechanisms of PSP in improving insulin resistance (IR) in skeletal muscle remain unclear. PA induced an IR model in L6 myotubes. After treatment, cell proliferation was measured using the CCK8.
