It is well established that maladaptive innate immune responses to sterile tissue injury represent a fundamental mechanism of disease pathogenesis. In the context of cardiac ischemia reperfusion injury, neutrophils enter inflamed heart tissue, where they play an important role...

Severe asthma (SA) is a significant problem both clinically and economically, given its poor response to corticosteroids (CS). We recently reported a complex type 1-dominated (IFN-γ-dominated) immune response in more than 50% of severe asthmatics despite high-dose CS treatment....

Infusion of in vitro-derived T cell progenitor (proT) therapy with hematopoietic stem cell transplant aids the recovery of the thymus damaged by total body irradiation. To understand the interaction between proTs and the thymic microenvironment, WT mice were lethally...

Nicotinamide metabolism regulates glioblastoma stem cell maintenance.

JCI insight

PMID: 28515364
JCI Insight. 2017 May 18;2(10). doi: 10.1172/jci.insight.90019. eCollection 2017 May 18.

Metabolic dysregulation promotes cancer growth through not only energy production, but also epigenetic reprogramming. Here, we report that a critical node in methyl donor metabolism, nicotinamide N-methyltransferase (NNMT), ranked among the most consistently overexpressed metabolism genes in glioblastoma relative...

Ceramide synthesis regulates T cell activity and GVHD development.

JCI insight

Sofi MH, Heinrichs J, Dany M, Nguyen H, Dai M, Bastian D, Schutt S, Wu Y, Daenthanasanmak A, Gencer S, Zivkovic A, Szulc Z, Stark H, Liu C, Chang YJ, Ogretmen B, Yu XZ.

JCI Insight. 2017 May 18;2(10). doi: 10.1172/jci.insight.91701. eCollection 2017 May 18.

Allogeneic hematopoietic cell transplantation (allo-HCT) is an effective immunotherapy for a variety of hematologic malignances, yet its efficacy is impeded by the development of graft-versus-host disease (GVHD). GVHD is characterized by activation, expansion, cytokine production, and migration of alloreactive...

Experimental lupus is aggravated in mouse strains with impaired induction of neutrophil extracellular traps.

JCI insight

Kienhöfer D, Hahn J, Stoof J, Csepregi JZ, Reinwald C, Urbonaviciute V, Johnsson C, Maueröder C, Podolska MJ, Biermann MH, Leppkes M, Harrer T, Hultqvist M, Olofsson P, Munoz LE, Mocsai A, Herrmann M, Schett G, Holmdahl R, Hoffmann MH.

JCI Insight. 2017 May 18;2(10). doi: 10.1172/jci.insight.92920. eCollection 2017 May 18.

Many effector mechanisms of neutrophils have been implicated in the pathogenesis of systemic lupus erythematosus (SLE). Neutrophil extracellular traps (NETs) have been assigned a particularly detrimental role. Here we investigated the functional impact of neutrophils and NETs on a...

Glioblastoma-infiltrated innate immune cells resemble M0 macrophage phenotype.

JCI insight

Gabrusiewicz K, Rodriguez B, Wei J, Hashimoto Y, Healy LM, Maiti SN, Thomas G, Zhou S, Wang Q, Elakkad A, Liebelt BD, Yaghi NK, Ezhilarasan R, Huang N, Weinberg JS, Prabhu SS, Rao G, Sawaya R, Langford LA, Bruner JM, Fuller GN, Bar-Or A, Li W, Colen RR, Curran MA, Bhat KP, Antel JP, Cooper LJ, Sulman EP, Heimberger AB.

JCI Insight. 2016;1(2). doi: 10.1172/jci.insight.85841. Epub 2016 Feb 25.

Glioblastomas are highly infiltrated by diverse immune cells, including microglia, macrophages, and myeloid-derived suppressor cells (MDSCs). Understanding the mechanisms by which glioblastoma-associated myeloid cells (GAMs) undergo metamorphosis into tumor-supportive cells, characterizing the heterogeneity of immune cell phenotypes within glioblastoma...

Characterization of candidate genes in inflammatory bowel disease-associated risk loci.

JCI insight

Peloquin JM, Goel G, Kong L, Huang H, Haritunians T, Sartor RB, Daly MJ, Newberry RD, McGovern DP, Yajnik V, Lira SA, Xavier RJ.
PMID: 27668286
JCI Insight. 2016 Aug 18;1(13):e87899. doi: 10.1172/jci.insight.87899.

GWAS have linked SNPs to risk of inflammatory bowel disease (IBD), but a systematic characterization of disease-associated genes has been lacking. Prior studies utilized microarrays that did not capture many genes encoded within risk loci or defined expression quantitative...

Enhanced protective antibody to a mutant meningococcal factor H-binding protein with low-factor H binding.

JCI insight

Granoff DM, Giuntini S, Gowans FA, Lujan E, Sharkey K, Beernink PT.

Perforin-2 is a highly conserved pore-forming protein encoded by macrophage expressed gene 1 (MPEG1). A number of studies have shown that Perforin-2-deficient mice are unable to survive following a bacterial challenge that is nonlethal in WT mice. There is...

β-catenin and PI3Kδ inhibition expands precursor Th17 cells with heightened stemness and antitumor activity.

JCI insight

ICOS costimulation generates Th17 cells with durable memory responses to tumor. Herein, we found that ICOS induces PI3K/p110δ/Akt and Wnt/β-catenin pathways in Th17 cells. Coinhibiting PI3Kδ and β-catenin altered the biological fate of Th17 cells. Th17 cells inhibited of...
