Cell death mediated by executioner caspases is essential during organ development and for organismal homeostasis. The mechanistic role of activated executioner caspases in antibacterial defense during infections with intracellular bacteria, such as Listeria monocytogenes, remains elusive. Cell death upon intracellular bacterial infections is considered altruistic to deprive the pathogens of their protective niche.

The glycolytic enzyme γ-enolase is a highly specific neuronal marker that is known to replace ubiquitously expressed α-enolase in the brain. Moreover, γ-enolase has been shown to exert neurotrophic activity, which is regulated by cathepsin X, a lysosomal peptidase. This study investigates the role of γ-enolase and its regulation by cathepsin X during the differentiation of oligodendrocytes, which are essential for normal brain function.

Patinopecten yessoensis (Yesso scallop), one of the most important aquaculture molluscs in China, has recently suffered severe Polydora disease, causing economic losses. Cathepsin L (CatL), a cysteine protease, has important functions in immune responses in vertebrates and invertebrates. However, little is known regarding the structure and function of CatL in scallops.

This study analyzed dipeptidyl peptidase-IV (DPP-IV) inhibitory peptides from Tartary buckwheat (Fagopyrum tataricum) protein hydrolysates, known for managing chronic diseases. Simulated gastrointestinal digestion enhanced the inhibitory activity of DPP-IV. Using anion-exchange resin DEAE-52, reverse high-performance liquid chromatography, and LC-MS/MS, eight novel peptides were identified.
