Cobalt nanoparticles induce mitochondrial damage and β-amyloid toxicity via the generation of reactive oxygen species.

Exposure to cobalt nanoparticles (CoNPs) has been associated with neurodegenerative disorders, while the mitochondrial-associated mechanisms that mediate their neurotoxicity have yet to be fully characterized. In this study, we reported that CoNPs exposure reduced the survival and lifespan in the nematodes, Caenorhabditis elegans (C. elegans).

JNK‑IN‑8 treatment alleviates lipopolysaccharide‑induced acute lung injury via suppression of inflammation and oxidative stress regulated by JNK/NF‑κB signaling.

JNK serves critical roles in numerous types of inflammation‑ and oxidative stress‑induced disease, including acute lung injury (ALI). JNK‑IN‑8 is the first irreversible JNK inhibitor that has been described. However, whether JNK‑IN‑8 can prevent lipopolysaccharide (LPS)‑induced ALI by inhibiting JNK activation and its downstream signaling is poorly understood.

Pretreatment with AM1241 Enhances the Analgesic Effect of Intrathecally Administrated Mesenchymal Stem Cells.

Mesenchymal stem cells have cannabinoid (CB) receptors type 1 and type 2 and can alleviate a variety of neuropathic pains, including chronic constriction injury (CCI). A selective CB2 receptor agonist is AM1241. In the present study, it was found that mice with CCI displayed a longer duration of mechanical and thermal analgesia when intrathecally (i.
