Amino acid metabolism provides significant insight into the development and prevention of many viral diseases. Therefore, present study aimed to compare amino profiles hand, foot, mouth disease (HFMD) patients with those healthy individuals further reveal molecular mechanisms HFMD severity. Using UPLC-MS/MS, we determined plasma expression pediatric (mild, n = 42; severe, 43) controls (n 25). Brain tissues from CVA6-infected mice were examined using untargeted metabolomics. Several acids significantly different between three groups. Pathway analysis revealed that arginine, proline, tryptophan are implicated in pathogenesis HFMD. A similar arginine depletion was observed brain mice. Importantly, L-arginine supplementation improved survival rate mice, inhibited virus multiplication, reduced pathological autophagy associated mTOR-autophagy pathway brain. Collectively, as hub metabolite mammalian target rapamycin (mTOR) signaling affecting autophagy, plays an important role severe may serve a potential therapeutic option for critical

Kynurenic acid (KYNA) is an antioxidant degradation product of tryptophan that has been shown to have a variety cytoprotective, neuroprotective and neuronal signalling properties. However, mammalian transporters receptors display micromolar binding constants; these are consistent with its typically tissue concentrations but far above serum/plasma concentration (normally tens nanomolar), suggesting large gaps in our knowledge transport mechanisms action, the main influx characterized date equilibrative, not concentrative. In addition, it substrate known anion efflux pump (ABCC4), whose vivo activity largely unknown. Exogeneous addition L-tryptophan or L-kynurenine leads production KYNA also many other co-metabolites (including some such as 3-hydroxy-L-kynurenine quinolinic may be toxic). With exception chestnut honey, exists at relatively low levels natural foodstuffs. bioavailability reasonable, terminal element irreversible reaction most pathways, might added exogenously without disturbing upstream metabolism significantly. Many examples, which we review, show valuable bioactivity. Given above, review potential utility nutraceutical, finding significantly worthy further study development.

Sirtuin 1 (SIRT1), a NAD+ -dependent histone deacetylase, plays crucial role in mitigating oxidative stress, regulating inflammation, and maintaining mitochondrial function. Reduced SIRT1 activity has been linked to elevated pro-inflammatory cytokines, dysfunction, chronic pain, all of which are observed long COVID pathology. Emerging evidence identifies dysfunction stress as central contributors these symptoms. Increases reactive oxygen species (ROS) such superoxide, nitric oxide, peroxynitrite, leading damage, central/peripheral sensitization. Nutraceuticals, particularly the polyphenolic fraction bergamot (BPF), have demonstrated potent antioxidant, anti-inflammatory, antiviral properties. This study highlights BPF's ability modulate rat model inflammation hyperalgesia. It provides novel nitration within nucleus key event inflammatory pain pathogenesis. BPF administration preserved activity, reduced markers malondialdehyde (MDA) 8-hydroxydeoxyguanosine (8-OHdG), minimized post-translational modifications nuclear proteins, including nitration, acetylation, carbonylation. Additionally, it alleviated hyperalgesia allodynia. These findings underscore therapeutic potential polyphenols like reducing inflammation-driven pain. By activating SIRT1, may provide relief for conditions. Further research on SIRT1-targeted therapies is essential combat preventing conditions enhancing treatment options.
