Late #WeekendRead: We describe a novel reporter to visualize endogenous #inflammasome assembly. Suitable for cell lines, primary cells, and tissues as well as quantification by #microscopy and #flowcytometry. Happy to share. biorxiv.org/content/10.110…

How could we identify key genes involved in any biological process and cell type? Please read on about Nuclear In-Situ Sequencing (NIS-Seq) nature.com/articles/s4158…

@IpbsToulouse @MariaMMota2 @LennonLab This was truly a lot of fun - excellent talks at @IpbsToulouse (and was also spoiled with good food). Thanks to all the students and staff members for organizing this!

and so it begins.....science needs to start getting serious about how how to deal with this type of attacks, sowing distrust.

Epic effort from Flo & first author Lisa Schiffelers of @FISchmidtLab . Antagonistic camelid #nanobodies are small enough to traverse early #GSDMD pores to inhibit further #pore #formation. Monomers target the membrane, suggesting #monomer to #oligomer transition on #membrane.

In parellel work, @anja_kopp @Geyer_lab solved the structure of two of our #nanobodies bound to #GSDMD. nature.com/articles/s4146…. The Feng Shao lab also used #AAV to express one of our #GSDMD #nanobodies to prevent loss of the #BBB during sepsis. nature.com/articles/s4158…

We think the antagonistic GSDMD #nanobodies enter cells when the first #GSDMD pores form. They prevent any further pore formation and thus -in combination with cellular repair mechanism- prevent cell death by pyroptosis. We are looking forward to test this concept in vivo ...

As #nanobodies enter pyroptotic cells (left), Lisa also tested if recombinant #nanobodies prevent pyroptosis when added to the medium during #inflammasome activation (right). They do!

We learn: 1. The plasma membrane is the first #GSDMD target membrane, 2. Cleavage of #GSDMD is sufficient to allow membrane insertion (no prepore required), and 3. #GSDMD pores are rapidly removed as soon as pores form.

As cells no longer die by #pyroptosis, stabilized, endogenous #GSDMD in the plasma membrane can even stained with antibodies for cleaved GSDMD.
