Characterization and heterologous expression of plasmalogen synthase MeHAD from Megasphaera elsdenii
Biochim Biophys Acta Mol Cell Biol Lipids. 2023 Jun 20:159358. doi: 10.1016/j.bbalip.2023.159358. Online ahead of print.ABSTRACTPlasmalogens (Pls) are vinyl-ether bond-containing glycerophospholipids or glycosyl diradyl glycerols, and are of great importance in the physiological functions and stability of cell membrane. Here, we identified and characterized that the plasmalogen synthase MeHAD from anaerobic Megasphaera elsdenii was responsible for vinyl-ether bond formation. Different from the 2-hydroxyacyl-CoA dehydratase (HAD) family plasmalogen synthase PlsA-PlsR which are encoded by two genes in Clostridium perfringens...

Phagocyte extracellular traps formation contributes to host defense against Clostridium perfringens infection
Cytokine. 2023 Jun 18;169:156276. doi: 10.1016/j.cyto.2023.156276. Online ahead of print.ABSTRACTClostridium perfringens (C. perfringens) is an important Gram-positive anaerobic spore-forming pathogen that provokes life-threatening gas gangrene and acute enterotoxaemia, although it colonizes as a component of the symbiotic bacteria in humans and animals. However, the mechanisms by which C. perfringens is cleared from the host remains poorly understood, thereby impeding the development of novel strategies for control this infection. Here, we uncover a beneficial effect of extracellular traps (ETs) formation on bacterial kil...
