Spinal astrocyte-derived interleukin-17A promotes pain hypersensitivity in bone cancer mice.

Spinal microglia and astrocytes are both involved in neuropathic and inflammatory pain, which may display sexual dimorphism. Here, we demonstrate that the sustained activation of spinal astrocytes and astrocyte-derived interleukin (IL)-17A promotes the progression of mouse bone cancer pain without sex differences. Chemogenetic or pharmacological inhibition of spinal astrocytes effectively ameliorates bone cancer-induced pain-like behaviors.

JMJD8 regulates neuropathic pain by affecting spinal cord astrocyte differentiation.

The demethylase JmjC structural domain-containing protein 8 (JMJD8) has been demonstrated to be involved in cellular inflammatory responses. Neuropathic pain (NP) is a chronic pain, and it is unclear whether JMJD8 is involved in the regulation of NP. Using a chronic constriction injury (CCI) mouse model of NP, we investigated the expression levels of JMJD8 during NP and the influences of JMJD8 on regulating pain sensitivity.

Global Landscape of Native Protein Complexes in Synechocystis sp. PCC 6803.

Synechocystis sp. PCC 6803 (hereafter: Synechocystis) is a model organism for studying photosynthesis, energy metabolism, and environmental stress. Although known as the first fully sequenced phototrophic organism, Synechocystis still has almost half of its proteome without functional annotations.

Dynamic expression of intra- and extra-cellular proteome and the influence of epiphytic bacteria for Nostoc flagelliforme in response to rehydration.

Nostoc flagelliforme is well known for its strong ecological adaptability in inhabiting desert biological soil crusts. However, the mechanism of its recovery from quiescent to active state after prolonged dormancy remains poorly characterized. Especially how exoproteome be related to the adaptive strategies and participate in the microalgae-bacteria interaction.
