Immune cell profiling from pleural fluid offers prognostic value and potential targets in lung cancer: doi.org/10.1172/jci.insight.…
This issue’s Cover features work by Khatri et al., reporting that macrophage reprogramming is associated with poor survival outcomes for patients with metastasis of #LungCancer to the pleural space. The cover image shows tumor-associated macrophages (CD163, red) surrounding an invading lung cancer metastatic lesion (pan-cytokeratin, green). Credit: Aaditya Khatri.

Research Spotlight💫: A promising targeted therapy approach to overcome OXPHOS-dependent resistance in acute myeloid leukemia (AML): doi.org/10.1172/jci.insight.…
Goutham Narla @gouthamnarla & team @UMich report on a new PP2A-B56α-based strategy that overcomes treatment resistance in preclinical AML models by targeting cell metabolism. Mechanistically, stabilization of the PP2A-B56α complex overcomes venetoclax-azacitidine resistance by impairing OXPHOS.

Halloween Highlight💫 : The ghoulish figure in this full spectrum flow cytometry and mass cytometry plot embodies how fibrosis-associated endothelial cells turn nasty during #LiverDisease: doi.org/10.1172/jci.insight.…
Mapping vascular plasticity during fibrogenesis identifies fibrosis-associated endothelial cells in early-stage liver disease by Gkantsinikoudi et al.:
The plot was generated by overlaying the different treatment groups with the 4 different clusters of expanded fibrosis associated endothelial cells (FAEC).
Dufton and colleagues spotted another eerie connection in their work. They named this image A Scarry Night after its resemblance to a Starry Night by Van Gogh as well as its nexus with scar tissue. It shows the stages of endothelial-to-mesenchymal transition (EndMT) of healthy liver EC (blue) as they express increasing amounts of TAGLN (red) going counterclockwise.
The first mouse safety study of #Ebola vaccine in pregnancy finds it largely safe, but early vaccination can increase fetal loss via interferon signaling: doi.org/10.1172/jci.insight.…
Sandra M. Blois @Blois_Lab & team established a pregnant mouse model for investigating the effects of VSV-EBOV vaccination on pregnancy outcomes and fetal development. Vaccination at various gestation revealed early timepoints raised pregnancy loss.

Dorina Avram @dorina_avram & team @MoffittNews initially observed reduced levels of the E3 ubiquitin ligase HECTD3 in colon samples from patients with ulcerative colitis: doi.org/10.1172/jci.insight.…
Using a murine colitis model, the researchers reveal how HECTD3 controls immune colonic inflammation and protects against colitis by restricting MyD88 activation and signaling.

A new, orally bioavailable DYRK1A inhibitor Leucettinib-92 LCTB-92 as a first-in-class therapy for treating myocardial infarction in a preclinical animal model: doi.org/10.1172/jci.insight.…
Matthew J. Wolf @MattWolfMDPhD & team @UVA find Inhibition of DYRK1A using LCTB-92 induces cardiomyocyte proliferation and improves heart function in a mouse model of ischemic/reperfusion injury. The team developed a computational network model to predict experimental outcomes then validated the predictions using selective DYRK1A inhibitors.
The images show circled regions with GFP+ cardiomyocytes, indicating cell cycle re-entry after ischemia/reperfusion myocardial infarction.

But please check our our paper - there's a lot more in there for helping Castleman Disease patients to be diagnosed in a more timely way and to help others who share our passion for the overlooked roles of lymph node stromal cells in human disease! insight.jci.org/articles/vie…

Wanted to share our years-long effort to understand the role of lymph node stromal cells in Castleman!
One of the biggest repositories of human lymph node stromal cell data.

More future physician-scientists are applying for their first NIH grant, and fewer are getting awarded. Our national survey of 256 trainees found what holds them back and what helps

What if Mycobacterium tuberculosis couldn’t evade macrophage defenses? Campos et al. @UTSWMedCenter identify SMURF2 as a conserved negative regulator of selective autophagy that suppresses macrophage control of M. tuberculosis: doi.org/10.1172/jci.insight.…
The figure shows increased phagosomal association in human macrophages exposed to the SMURF2 inhibitor Heclin.

We show that stabilizing PP2A-B56α can overcome venetoclax–azacitidine resistance in acute myeloid leukemia by targeting mitochondrial metabolism.
Sunday Read💫: A novel axis that can fine-tune the immune response to glomerular and tubule cell damage: doi.org/10.1172/jci.insight.…
Jamie R. Privratsky @JamiePrivratsky & team @DukeKidney @Duke_Anesthesia identify a novel myeloid cell-endothelial cell immunoregulatory axis, supporting a model whereby myeloid IL-1R1 activity constrains ER stress–mediated EBI3/IL27 secretion, thereby attenuating type I IFN expression in kidney endothelial cells and ameliorating
autoimmune nephritis.
The figure shows anti-IFNAR1 therapy abrogates kidney injury after NTS nephritis in mice lacking IL-1R1 specifically in myeloid cells (bottom); littermate controls (top).

Saturday Highlight💫: Full-length macrophage TREM2 protects against atherosclerosis: doi.org/10.1172/jci.insight.…
Tang et al. unravel the links between #Prediabetes, #CardiovascularDisease, and #HepaticSeatosis, identifying increased levels of soluble TREM2 in human subjects and preclinical models of prediabetes. Soluble, macrophage-derived TREM2 associated with plasma apolipoprotein C3, which in turn reduces clearance of triglyceride-rich lipoproteins and increases heart disease risk. Importantly, preservation of full length TREM2 in prediabetic, steatotic mice reduced dyslipidemia and atherosclerosis.
This study links faulty DNA repair to abnormal immune responses: doi.org/10.1172/jci.insight.…
