RHOA Deletion Downregulates CD19 and Promotes Dysfunctional Immune Microenvironments in CAR-T Resistant Large B-cell Lymphomas
Abstract. CD19-directed chimeric antigen receptor (CAR)-T cells are breakthrough therapies for large B-cell lymphomas, but fewer than half of patients achieve durable responses. We previously showed R...

BLUETORIAL 6) Read our paper for the fascinating mechanisms of how this all works. Incredible work by our first and many contributing authors over the past several years!

Jonathan Schatz @drjonschatzmd.bsky.social · 03/02/2025
BLUETORIAL 5) We find, however, that a combination of BTK inhibitor, in particular the potent non-covalent compound pirtobrutinib, and venetoclax overcomes resistance. BTK therefore maintains a role in driving resistance even when CBM is activated downstream by BCL10 mutations.
000
Jonathan Schatz @drjonschatzmd.bsky.social · 03/02/2025
BLUETORIAL 4) BCL10 mutations cluster in BN2/C1 DLBCL cases, which are known to be resistant to BTK inhibitors. We find that BCL10 mutations, in addition to driving BTK inhibitor resistance, drive resistance to multiple other classes of drug, including the BCL2 inhibitor venetoclax
000
Jonathan Schatz @drjonschatzmd.bsky.social · 03/02/2025
BLUETORIAL 3) Our work now elaborates on the signaling and therapeutic consequences of these activating mechanisms. Detailed gene-expression and mechanistic work shows how mutant-BCL10 mediated CBM activation establishes a cytokine-reinforced positive-feedback loop of lymphomagenesis
000
Jonathan Schatz @drjonschatzmd.bsky.social · 03/02/2025
BLUETORIAL 2) Amazing work by the Ari Melnick lab demonstrated both these classes of mutation activate the protein's role in signaling by way of the BCL10-CARD11-MALT1 (CBM) complex. R58Q stablizes signaling, the truncations remove an inhibitory domain allowing spontaneous complex activation.
000
Jonathan Schatz @drjonschatzmd.bsky.social · 03/02/2025
Bluetorial 1) BCL10 is recurrently mutated in DLBCL cases with a fascinating pattern: The N-terminal CARD domain has a hotspot missense mutation (R58Q) consistent with gain of function, while the C-terminal is recurrently truncated consistent with loss of function.

It’s an open secret among medical professionals: Many drugs maintain their ability to combat ailments well after their expiration date. One pharmacist says he sometimes takes home expired OTC medicine so he and his family can use it. (Published 2017, but there's no expiration date for this story)

The Myth of Drug Expiration Dates
Hospitals and pharmacies are required to toss expired drugs, no matter how expensive or vital. Meanwhile the FDA has long known that many remain safe and potent for years longer.
