Congratulations to Bobby and Humayun for their recent Nature paper, "DPP9 sequesters the C terminus of NLRP1 to repress inflammasome activation"
"Nucleotide-binding domain and leucine-rich repeat pyrin-domain containing protein 1 (NLRP1) is an infammasome sensor that mediates the activation of caspase-1 to induce cytokine maturation and pyroptosis . Gain-of-function mutations of NLRP1 cause severe infammatory diseases of the skin. NLRP1 contains a function-to-fnd domain that auto-proteolyses into noncovalently associated subdomains, and proteasomal degradation of the repressive N-terminal fragment of NLRP1 releases its infammatory C-terminal fragment (NLRP1 CT)."

Congratulations to Venkat and Roberto for their recent Science paper, "HDAC6 mediates an aggresome-like mechanism for NLRP3 and pyrin inflammasome activation"
"Inflammasomes are supramolecular complexes that play key roles in immune surveillance. This is accomplished by the activation of inflammatory caspases, which leads to the proteolytic maturation of interleukin 1β (IL-1β) and pyroptosis. Here, we show that nucleotide-binding domain, leucine-rich repeat, and pyrin domain-containg protein 3 (NLRP3)- and pyrin-mediated inflammasome assembly, caspase activation, and IL-1β conversion occur at the microtuble-organizing center (MTOC)."

Congratulations to Jacob and Shiyu for their recent Nature Immunology paper, "FDA-approved disulfiram inhibits pyroptosis by blocking gasdermin D pore formation"
"Inflammation is the alarm system by which cells first respond to potential danger, but in excess, inflammation can be fatal. In COVID-19, for example, overactive inflammation has led to severe complications and even death for many hospitalized patients. Research in mice led by Harvard Medical School and Boston Children’s Hospital now reveals that the FDA-approved drug disulfiram, commonly used for treating alcoholism, blocks a key gatekeeper protein involved in inflammation."

Congratulations to Humayun, Li, and Weili for their recent Nature paper, "Structural mechanism for NEK7-licensed activation of NLRP3 inflammasome"
June 2019 | PDF | Nature News & Views Feature Article
"The NLRP3 inflammasome can be activated by stimuli that include nigericin, uric acid crystals, amyloid-β fibrils and extracellular ATP. The mitotic kinase NEK7 licenses the assembly and activation of the NLRP3 inflammasome in interphase. Here we report a cryo-electron microscopy structure of inactive human NLRP3 in complex with NEK7, at a resolution of 3.8 Å. The earring-shaped NLRP3 consists of curved leucine-rich-repeat and globular NACHT domains..." Continue reading
