Journal ArticleDOI
Autophagy-based unconventional secretory pathway for extracellular delivery of IL-1β
Nicolas Dupont,Shanya Jiang,Manohar Pilli,Wojciech Ornatowski,Dhruva Bhattacharya,Vojo Deretic +5 more
TL;DR: This work shows that in mammalian cells, autophagy has a hitherto unappreciated positive contribution to the biogenesis and secretion of the proinflammatory cytokine IL‐1β via an export pathway that depends on Atg5, inflammasome, at least one of the two mammalian Golgi reassembly stacking protein (GRASP) paralogues, GRASP55 (GORASP2) and Rab8a.
Journal ArticleDOI
TBK-1 Promotes Autophagy-Mediated Antimicrobial Defense by Controlling Autophagosome Maturation
Manohar Pilli,John Arko-Mensah,Marisa Ponpuak,Marisa Ponpuak,Esteban A. Roberts,Sharon Master,Michael A. Mandell,Nicolas Dupont,Wojciech Ornatowski,Shanya Jiang,Steven B. Bradfute,Jack-Ansgar Bruun,Tom Egil Hansen,Terje Johansen,Vojo Deretic +14 more
TL;DR: TBK-1 is a key regulator of immunological autophagy and is responsible for the maturation of autophagosomes into lytic bactericidal organelles.
Journal ArticleDOI
Autophagy protects against active tuberculosis by suppressing bacterial burden and inflammation
Eliseo F. Castillo,Alexander Dekonenko,John Arko-Mensah,Michael A. Mandell,Nicolas Dupont,Shanya Jiang,Monica Delgado-Vargas,Graham S. Timmins,Dhruva Bhattacharya,Hongliang Yang,Julie A. Hutt,C. Rick Lyons,Karen M. Dobos,Vojo Deretic +13 more
TL;DR: It is shown that autophagy plays a dual role against tuberculosis: antibacterial and anti-inflammatory, suppressing both M. tuberculosis growth and damaging inflammation.
Journal ArticleDOI
Dedicated SNAREs and specialized TRIM cargo receptors mediate secretory autophagy.
Tomonori Kimura,Jingyue Jia,Suresh Kumar,Seong Won Choi,Yuexi Gu,Michal H. Mudd,Nicolas Dupont,Shanya Jiang,Ryan Peters,Farzin Farzam,Ashish Jain,Keith A. Lidke,Christopher M. Adams,Terje Johansen,Vojo Deretic +14 more
TL;DR: It is shown that in response to lysosomal damage, the prototypical cytosolic secretory autophagy cargo IL‐1β is recognized by specialized secretoryautosolic cargo receptor TRIM16 and that this receptor interacts with the R‐SNARE Sec22b to recruit cargo to the LC3‐II+ sequestration membranes.
Journal ArticleDOI
Neutral lipid stores and lipase PNPLA5 contribute to autophagosome biogenesis
Nicolas Dupont,Nicolas Dupont,Santosh Chauhan,John Arko-Mensah,Eliseo F. Castillo,Andrius Masedunskas,Roberto Weigert,Horst Robenek,Tassula Proikas-Cezanne,Vojo Deretic +9 more
TL;DR: It is shown that lipid droplets as cellular stores of neutral lipids including triglycerides contribute to autophagic initiation in a process dependent on PNPLA5, which was needed for optimal initiation of autophagy.
