pyro ZBP1 promotes fungi-induced inflammasome activation and pyroptosis, apoptosis, and necroptosis (PANoptosis) [Microbiology] By www.jbc.org Published On :: 2020-12-25T00:06:31-08:00 Candida albicans and Aspergillus fumigatus are dangerous fungal pathogens with high morbidity and mortality, particularly in immunocompromised patients. Innate immune-mediated programmed cell death (pyroptosis, apoptosis, necroptosis) is an integral part of host defense against pathogens. Inflammasomes, which are canonically formed upstream of pyroptosis, have been characterized as key mediators of fungal sensing and drivers of proinflammatory responses. However, the specific cell death pathways and key upstream sensors activated in the context of Candida and Aspergillus infections are unknown. Here, we report that C. albicans and A. fumigatus infection induced inflammatory programmed cell death in the form of pyroptosis, apoptosis, and necroptosis (PANoptosis). Further, we identified the innate immune sensor Z-DNA binding protein 1 (ZBP1) as the apical sensor of fungal infection responsible for activating the inflammasome/pyroptosis, apoptosis, and necroptosis. The Zα2 domain of ZBP1 was required to promote this inflammasome activation and PANoptosis. Overall, our results demonstrate that C. albicans and A. fumigatus induce PANoptosis and that ZBP1 plays a vital role in inflammasome activation and PANoptosis in response to fungal pathogens.

pyro Spyro Reignited Trilogy Headed to Xbox Game Pass Tomorrow, November 12 By www.vgchartz.com Published On :: Mon, 11 Nov 2024 16:26:38 GMT Following a tease, Microsoft and Activision Blizzard have announced Spyro Reignited Trilogy will release for Xbox Game Pass tomorrow, November 12. VGChartz staff gave Spyro Reignited Trilogy an 8 out of 10 and stated, "it was wise to steer away from marketing the collection as a remaster because that label undercuts the developers’ level of dedication and investment in revitalizing these games." Read details on the trilogy below: Remade from the ground up, the Spyro Reignited Trilogy features all three of the original games that started it all – Spyro the Dragon, Spyro 2: Ripto’s Rage, and Spyro: Year of the Dragon, amazing for the original fans and new players alike. Spyro the Dragon Our new favorite little purple dragon starts on a quest to rescue his dragon friends who have been turned into crystal by the villain Gnasty Gnorc (what an unfortunate and yet apt name!). Spyro explores vibrant Dragon Realms, collects gems, and flambés his enemies, all while learning to how breathe fire and glide. Spyro 2: Ripto’s Rage! Spyro finds himself in the magical land of Avalar where he is trying to save the realm from the evil sorcerer Ripto and his minions. Along the way, he befriends new entirely new allies, overcomes challenges, complete tasks, and unlocks even more powers to take down Ripto and restore peace. Spyro: Year of the Dragon In Spyro: Year of the Dragon, Spyro finds out that the Dragon Eggs have been stolen by the devious Sorceress, sending him on a new mission to recover the eggs and save the dragon population. Our favorite purple dragon meets new friends, learns new abilities, all while exploring more vibrant realms with challenges (and treasures!). Xbox players have been able to explore the Dragon Realms with Spyro since 2018 with the release of the Reignited Trilogy, and now we’re excited to invite our community to jump into these incredible adventures once again and relive the fun and nostalgia that only Spyro can bring. Available on Game Pass Standard, Game Pass Ultimate, and PC Game Pass, for cloud, console and PC, it’s sure to ignite some serious fun. Let’s go save the Dragon Realms! A life-long and avid gamer, William D'Angelo was first introduced to VGChartz in 2007. After years of supporting the site, he was brought on in 2010 as a junior analyst, working his way up to lead analyst in 2012 and taking over the hardware estimates in 2017.

pyro Mechanical pyrolysis in a shear retort By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT Mechanical visbreaking and pyrolysis between counter-rotating coaxial centrifugal impellers in a continuous radial counterflow process minimizes wastewater discharges. In one example, a cataclastic shear retort comminutes, shear thins, and shear heats an axial feed, such as tar sand, oil shale, coal tailings, distillation bottoms, or lignite. Pyrolyzing the feedstock in this shear retort yields a product stream of gases, naphthas, and oils which first mixes with the feedstock and then is axially extracted, while spent solids are simultaneously extruded from the periphery as coked devolatilized residue, such as char sand for upgrading soil to terra preta. Recirculation of shear-heated solids in long residence time within the shear retort brings heat from the spent solids at the periphery to the feedstock without an external heated sand loop. CO2 emissions from combustion to heat water for oil extraction are eliminated. Full Article

pyro Bubbling bed catalytic hydropyrolysis process utilizing larger catalyst particles and smaller biomass particles featuring an anti-slugging reactor By www.freepatentsonline.com Published On :: Tue, 23 Sep 2014 08:00:00 EDT This invention relates to a process for thermochemically transforming biomass or other oxygenated feedstocks into high quality liquid hydrocarbon fuels. In particular, a catalytic hydropyrolysis reactor, containing a deep bed of fluidized catalyst particles is utilized to accept particles of biomass or other oxygenated feedstocks that are significantly smaller than the particles of catalyst in the fluidized bed. The reactor features an insert or other structure disposed within the reactor vessel that inhibits slugging of the bed and thereby minimizes attrition of the catalyst. Within the bed, the biomass feedstock is converted into a vapor-phase product, containing hydrocarbon molecules and other process vapors, and an entrained solid char product, which is separated from the vapor stream after the vapor stream has been exhausted from the top of the reactor. When the product vapor stream is cooled to ambient temperatures, a significant proportion of the hydrocarbons in the product vapor stream can be recovered as a liquid stream of hydrophobic hydrocarbons, with properties consistent with those of gasoline, kerosene, and diesel fuel. Separate streams of gasoline, kerosene, and diesel fuel may also be obtained, either via selective condensation of each type of fuel, or via later distillation of the combined hydrocarbon liquid.

pyro [Cell Biology] Recent Insights on Inflammasomes, Gasdermin Pores, and Pyroptosis By cshperspectives.cshlp.org Published On :: 2020-05-01T06:30:17-07:00 Inflammasomes assemble in the cytosol of myeloid and epithelial cells on sensing of cellular stress and pathogen-associated molecular patterns and serve as scaffolds for recruitment and activation of inflammatory caspases. Inflammasomes play beneficial roles in host and immune responses against diverse pathogens but may also promote inflammatory tissue damage if uncontrolled. Gasdermin D (GSDMD) is a recently identified substrate of murine caspase-1 and caspase-11, and human caspases-1, -4, and -5 that mediates a regulated lytic cell death mode termed pyroptosis. Recent studies have identified pyroptosis as a critical inflammasome effector mechanism that controls inflammasome-dependent cytokine secretion and contributes to antimicrobial defense and inflammasome-mediated autoinflammatory diseases. Here, we review recent developments on inflammasome-associated effector functions with an emphasis on the emerging roles of gasdermin pores and pyroptosis. Full Article
