This study defines a new clinically relevant concept of T-cell senescence-mediated inflammatory responses in the pathophysiology of abnormal glucose homeostasis. We also found that T-cell senescence is associated with systemic inflammation and alters hepatic glucose homeostasis. The rational modulation of T-cell senescence would be a promising avenue for the treatment or prevention of diabetes.

This study examined the levels of neuroinflammatory proteins in the spinal cord of JGT-treated hSOD1 G93A transgenic mice to determine the effect of Jaeumganghwa-Tang (JGT) on neuroinflammation. Twelve 8-week-old male experimental mice were randomly allocated to three groups: a non-transgenic group, a hSOD1G93A transgenic group, and a hSOD1G93A transgenic group that received JGT 1 mg/g orally once daily for 6 weeks. After 6 weeks, the spinal cord tissues were analyzed for inflammatory proteins (Iba-1, toll-like receptor 4, and tumor necrosis factor-α) and oxidative stress-related proteins (transferrin, ferriti...

DiscussionAs this SNP is known to modify the detoxifying activity of paraxonase 1 with respect to different substrates as well as other activities of the protein, we hypothesize that the identified association might reflect specific motor neuron vulnerability to certain exogenous toxic substances metabolized less efficiently by the 192R alloenzyme, or to detrimental endogenous pathophysiological processes such as oxidative stress. Further exploration of this possible metabolic susceptibility could deepen our knowledge of ALS pathomechanisms.

In recent years researchers have investigated changes in alternative splicing in the context of aging and age-related disease. It is thought to be important in cellular senescence, for example, but that is just one line item in the bigger picture. A given gene can code for multiple different proteins, and alternative splicing is the name given to the processes by which those different proteins are produced. A gene contains discrete DNA sequences called exons and introns, the former passed into the protein production process, and the latter removed during RNA splicing. The canonical protein produced from this genetic bluepr...

Publication date: Available online 21 March 2019Source: Journal of Molecular BiologyAuthor(s): Sei-Kyoung Park, Sangeun Park, Susan W. LiebmanAbstractThe trans-activating response DNA-binding protein 43 (TDP-43) is a transcriptional repressor and splicing factor. TDP-43 is normally mostly in the nucleus, although it shuttles to the cytoplasm. Mutations in TDP-43 are one cause of familial amyotrophic lateral sclerosis (ALS). In neurons of these patients, TDP-43 forms cytoplasmic aggregates. In addition, wild-type TDP-43 is also frequently found in neuronal cytoplasmic aggregates in patients with neurodegenerative diseases n...
