Vesicular MASS transmission of Virus

subject: Phosphatidylserine Vesicles Enable Efficient En Bloc Transmission of Enteroviruses
object_opposite: Release of viral particles one at a time, Old paradigm:A central paradigm within virology is that each viral particle largely behaves as an independent infectious unit. Here, we demonstrate that clusters of enteroviral particles are packaged within phosphatidylserine (PS) lipid-enriched vesicles that are non-lytically released from cells and provide greater infection efficiency than free single viral particles. We show that vesicular PS lipids are co-factors to the relevant enterovirus receptors in mediating subsequent infectivity and transmission, in particular to primary human macrophages. We demonstrate that clustered packaging of viral particles within vesicles enables multiple viral RNA genomes to be collectively transferred into single cells.

    Synopsis

    In addition to immune signaling pathways, glycolysis genes were strongly upregulated in terms of histone modification profiling, and this was validated by RNA sequencing of cells from β-glucan–treated mice. The biochemical characterizations of the β-glucan–trained monocytes revealed elevated aerobic glycolysis with reduced basal respiration rate, increased glucose consumption and lactate production, and higher intracellular ratio of nicotinamide adenine dinucleotide (NAD+) to its reduced form (NADH). The dectin-1–Akt–mTOR–HIF-1α pathway (mTOR, mammalian target of rapamycin; HIF-1α, hypoxia-inducible factor–1α) was responsible for the metabolic shift induced by β-glucan. Trained immunity was completely abrogated in monocytes from dectin-1–deficient patients. Blocking of the mTOR–HIF-1α pathway by chemical inhibitors inhibited trained immunity. Mice receiving metformin, an adenosine monophosphate–activated protein kinase (AMPK) activator that subsequently inhibits mTOR, lost the trained immunity–induced protection against lethal C. albicans infection. The role of the mTOR–HIF-1α pathway for β-glucan–induced innate immune memory was further validated in myeloid-specific HIF-1α knockout (mHIF-1α KO) mice that, unlike wild-type mice, were not protected against Staphylococcus aureus sepsis.

    Glycolytic yet sometimes nonmetabolic function of enzymes

    In my search for all of the possible connections with known metabolic activity and the cytokine cycle, I am always surprised at new connections. Here is an article citing not only transcription but apoptosis and cell motility to Glycolytic Enzymes. GAPD is
