    For those asking, the plots were made by the inordinately talented Kevin Bi in the lab using the viridis R package for the magma color palette, and standard stat_density_2d() in ggplot2 for underlaying point density in projection space.

    So, bottom line: 1) ADAR1 is an inhibitory checkpoint that prevents the sensing of dsRNA. Creating enough inflammation in tumors that are sensitized to interferon may bypass the need for CD8+ T cells and overcome immunotherapy resistance from loss of ag presentation...

    But the rather cherry-like finding on the experimental icing was that Adar null tumors are so IFN sensitive and so poised for inflammation, that even when we deleted B2m and made tumors invisible to CD8+ T cell immunity...checkpoint is still effective…

    (I hear you say: is this why we have SINEs? To make an IFN-inducible positive feedback loop and amplify IFN's effects? If it’s what you say, I love it). This IFN sensitivity also makes Adar null tumors exquisitely radio-sensitive (just for you, )

    Why? Seems that the SINEs that make dsRNA that are usually inhibited by ADAR are *themselves* IFN inducible.

    But what’s really interesting is that the sensitivity of Adar null tumors to immunotherapy is entirely dependent on IFN signaling (epistasis experiments nailed that one, thank you Collins and friends).

    In the tumor, if you lose Adar1, dsRNA can now triggers sensing by MDA5 (causing inflammation) and PKR (causing growth arrest). It’s a checkpoint, if you will, that limits dsRNA sensing.

    Now we’re clearly not the first people to figure out how Adar1 works ...it’s a deaminase that limits dsRNA sensing of SINEs and other endogenous retroelements. Lots of lovely work by Chris Walkley and the Rice lab has shown that.

    ...and did so with boat-loads of inflammation in the tumor microenvironment and lots of interferons produced (we're rather fond of Galaxy plots for our scRNA-seq data cc )

    So one of the interesting classes of genes that, when deleted, sensitized tumors to immunotherapy were genes that alter RNA sensing -- like Adar1. Huh. Why would a tumor care about RNA sensing? A lot as it turns out. Loss of Adar1 *really* sensitized tumors to immunotherapy…

    A while back we developed a nifty in vivo pooled CRISPR screen to find genes that sensitize tumors to checkpoint blockade. You didn’t see it? This one:

    Teachers! Parents! It is legal and perfectly welcome to email scientists asking for a PDF of their paper. Until all papers are free, please RT to make this more widely known. And fyi, scientists don't get the $$ from sales of papers so all it costs us is 1 minute of time!

ಲೋಡಿಂಗ್ ಸಮಯ ಸ್ವಲ್ಪ ತೆಗೆದುಕೊಳ್ಳುತ್ತಿರುವಂತೆನಿಸುತ್ತದೆ.

Twitter ಸಾಮರ್ಥ್ಯ ಮೀರಿರಬಹುದು ಅಥವಾ ಕ್ಷಣಿಕವಾದ ತೊಂದರೆಯನ್ನು ಅನುಭವಿಸುತ್ತಿರಬಹುದು. ಮತ್ತೆ ಪ್ರಯತ್ನಿಸಿ ಅಥವಾ ಹೆಚ್ಚಿನ ಮಾಹಿತಿಗೆ Twitter ಸ್ಥಿತಿಗೆ ಭೇಟಿ ನೀಡಿ.

    ಇದನ್ನೂ ಸಹ ನೀವು ಇಷ್ಟಪಡಬಹುದು
