Cingulum bundle stimulation reduces anxiety during awake neurosurgical proceduresCertain neurosurgeries must be performed on alert patients in order to continuously monitor motor, sensory, and language function. Understandably, many patients undergoing awake craniotomy experience anxiety that can make the procedure intolerable. In this issue of the JCI, Kelly Bijanki et al. describe a noteworthy observation that occurred during diagnostic intracranial electroencephalography (iEEG): low-intensity stimulation of the anterior cingulum bundle instantly improved the patient’s mood and reduced anxiety, and this stimulation was subsequently used to alleviate anxiety during her awake craniotomy for epilepsy. The cingulum bundle connects the limbic regions with prefrontal, parietal, and temporal lobes and contributes to cognitive and emotional responses. After the initial patient’s responses to the stimulation were noted, similar responses were documented in two additional patients undergoing iEEG. In an accompanying Commentary, Kelly Mills suggests that the stimulation’s anxiolytic and mood-enhancing effects, which occurred without changes in cognitive state or sedation, may make it a useful alternative to anxiolytic medications to manage patients’ tolerance of awake neurosurgical procedures. This issue’s cover depicts the position of the implanted electrode along the cingulum bundle, which is highlighted in pink. In the background, a man’s changing facial expressions represent one objective measurement of the stimulation’s effects. Image credit: Bona Kim, MA, CMI, Emory University Brain Health Center.

TP53 hot spot mutations are immunogenic targets for tumor-infiltrating T cells
neuroscience
Cellular immunotherapies utilizing adoptive transfer of tumor-infiltrating T cells have elicited successful clinical responses against a number of cancers. However, transferred T cells often target tumor neoantigens that are unique to an individual patient, making these cellular therapies time-consuming to develop. To identify a more broadly applicable target for cellular immunotherapies, Parisa Malekzadeh and colleagues sequenced and then screened for common immunogenic mutations in TP53, the most frequently mutated gene among all cancer types. They demonstrated that patient-derived tumor-infiltrating T cells were capable of targeting autologous TP53 “hot spot” mutations at commonly mutated positions. Further, they identified shared T cell receptors from mutation-responsive CD4+ and CD8+ T cells. Enrico Lugli, Pia Kvistborg, and Giovanni Galletti’s accompanying Commentary supports this study’s suggestion that cellular immunotherapies could be engineered to target neoantigens that are common in cancer.

Apolipoprotein E receptor interacts with Alzheimer’s risk allele in amyloid-β pathologyAmyloid-β accumulation in the brain precedes the development of amyloid plaques that are a diagnostic feature of Alzheimer’s disease (AD). The ε4 allele of the gene encoding apolipoprotein E (APOE4) is associated with increased AD risk, likely through an effect on amyloid-β metabolism. Masaya Tachibana, Marie-Louise Holm, and colleagues investigated the interaction of the apolipoprotein E receptor LRP1 with APOE4’s effects on amyloid pathology. In postmortem AD brains, the APOE4 allele was linked to elevated levels of insoluble amyloid-β as well as increased LRP1 expression relative to the ε3 allele (APOE3). In a mouse model of AD, APOE4-expressing mice displayed similar increases in amyloid-β deposition relative to APOE3-expressing mice; however, loss of neuronal LRP1 mitigated this increase (see the associated image). An accompanying Commentary by Michael Strickland and David Holtzman discusses these insights into mechanisms by which apolipoprotein E isoforms may differen-tially affect amyloid-β metabolism and AD risk.

Monoclonal antibody targets pathogenic IFN source in cutaneous lupus lesions
A primary antibody deficiency linked to loss of ARHGEF1Primary antibody deficiency (PAD) syndromes are characterized by failure to produce sufficient antibody responses to prevent infection. PAD is often linked to defects in B cell development, differentiation, or function, although the molecular mechanisms involved are often unclear. Amine Bouafia and colleagues identified two heterozygous loss-of-function mutations in the hematopoietic guanine nucleotide exchange factor ARHGEF1 in two siblings diagnosed with PAD. Both patients were deficient in marginal zone and memory B cells, but displayed abnormally high levels of transitional B cells and immature myeloid cells in blood. Impaired actin polymerization, prolonged AKT activation, and inefficient migration in the patients’ lymphocytes resembled the phenotype of Arhgef1-deficient mice. In the accompanying Commentary, Divij Mathew, Kimberly Kremer, and Raul Torres discuss how these findings provide insights into ARHGEF1’s role in the adaptive immune response in addition to identifying a novel cause of PAD.

immunology
Systemic lupus erythematosus (SLE) is character-ized by autoantibody production, chronic inflamma-tion, and pathologic activation of multiple proinflam-matory pathways, notably the type I IFN pathway. Plasmacytoid dendritic cells (pDCs), which produce large amounts of type I IFN, are considered a promising therapeutic target. Richard Furie and colleagues evaluated the safety and tolerability of a pDC-targeting monoclonal antibody (BIIB059) in 54 healthy volunteers and 12 SLE patients. BIIB059 was designed to bind to the pDC receptor BDCA2 and thereby limit type I IFN production. BIIB059 administration was well tolerated and resulted in favorable pharmacokinetic and pharmacodynamic profiles in healthy and SLE subjects. In SLE patients, a single dose of BIIB059 decreased expression of blood IFN response genes, normalized IFN activity, reduced inflammatory infiltrates in skin lesions, and decreased skin disease activity. Yashaar Chaichian,
Daniel J. Wallace, and Michael Weisman’s accompa-nying Commentary supports further study of BIIB059 as an intervention in SLE.

CD33 targeting suppresses mast cell–mediated anaphylaxis during antigen presentation
Platelet delivery of miR-223 regulates proliferative phase of arterial repair
immunology
Anaphylaxis is a severe allergic response that is initiated when allergen-specific IgE binds to its receptor on mast cells, triggering degranulation. Allergen immunotherapy can desensitize mast cell activation by exposing the patient to escalating doses of allergen; however, because of intolerable side effects, many patients discontinue treatment before reaching the therapeutic dose. Shiteng Duan and colleagues identified the mast cell receptor CD33 as a potential target for suppressing anaphylactic responses to antigen presentation. They show that antigen- presenting liposomes also bearing the high-affinity CD33 ligand CD33L suppressed allergen-induced mast cell activation. In a mouse model of anaphylaxis, the CD33L-bearing liposomes similarly inhibited mast cell activation and produced allergen-specific desensitization that lasted for several days. Finally, activating CD33 in human mast cells prevented IgE-mediated broncho-constriction in human lung tissue. In an accompanying Commentary, Stephen Galli outlines the evidence supporting CD33-mediated mast cell suppression as a potential strategy for treating severe allergic disease.
Arterial injury induces a multistage reparative process during which vascular smooth muscle cells (VSMCs) dedifferentiate, repopulate the damaged area, and finally return to a quiescent state. Prolonged VSMC proliferation can lead to intimal hyperplasia and restenosis, which are observed more frequently in diabetic individuals. While activated platelets are known to influence VSMC dedifferentiation via release of PDGF and cytokines, a study by Zhi Zeng and colleagues highlights their contribution to the timely resolution of the proliferative phase. In coculture experiments and in vivo lineage-tracing studies, they observed that the return to quiescence required VSMCs to internalize activated platelets (see the associated image). Horizontal transfer of miR-223 from internalized platelets inhibited PDGFRβ expression in VSMCs, inducing the latter’s switch to a quiescent phenotype. Noting an observation that uncontrolled glucose levels depress miR-223 expres-
sion, Elena Dolmatova and Kathy Griendling’s accompanying Commen-tary speculates on potentially targetable mechanisms underlying increased risk of restenosis in patients with diabetes.

Clashing perspectives on the future of precision medicine
Examining the autoimmune mechanisms contributing to encephalitis disorders and epilepsyRecent insights into the autoimmune basis of several encephalitis disorders have increased interest in potential autoimmune mechanisms underlying seizures and epilepsy. Several seizure-linked disorders, including Rasmussen’s encephalitis, are linked to immune responses to neuronal antibodies (see the accompanying image), and a number of drug-resistant epilepsies are accompanied by elevated levels of cytotoxic T cells and inflammatory molecules in the CNS. However, a review by Christian Geis, Jesus Planagumà, Mar Carreño, Francesc Graus, and Josep Dalmau urges prudence in differentiating between autoimmune epilepsy and the occurrence of seizures linked to autoimmune disease: while patients with autoimmune encephalitis disorders may experience a seizure, many do not go on to develop true epilepsy. This Review outlines a range of mechanisms by which CNS inflammation, neuronal hyperexcitability, and long-term synaptic dysfunction act in combination or independently to contribute to epileptogenesis.

Tissue-targeting strategies propel synthetic nucleic acid drug discoveryRecent FDA approvals of RNA-targeting treatments for Duchenne’s muscular dystrophy, spinal muscular atrophy, and other diseases highlight the potential of antisense oligonucleotides (ASOs) as therapeutic strategies. Successful development of ASO-based therapies for other diseases will be enhanced, in part, by ongoing advances in the ability to selectively deliver these drugs to specific tissues. Tissue targeting provides an opportunity to increase treatment potency, improve pharmacokinetic profile, and reduce toxicity of an ASO-based therapy. In this Review, Punit Seth, Michael Tanowitz, and Frank Bennett describe a variety of strategies that facilitate ASO delivery, including chemical modifications, conjugation to tissue-specific receptors or ligands, and encapsulation in lipid nanoparticles. Advances in tissue-specific targeting may also facilitate noninvasive ASO delivery to the CNS and other protected tissues.

Two Viewpoints in this issue address the achievements and future of precision medicine. The article by Michael Joyner and Nigel Paneth reflects on the aims of the Human Genome Project, which promised to deliver insights that would improve genetic disease, diagnostics, pharmacogenomics, preventive medicine, and gene therapy within our lifetimes. They argue that our current awareness of the limitations of precision medicine should inspire the medical community to reprioritize its investments in projects that may better meet our nation’s health needs. On the other hand, Antony Rosen and Scott Zeger take the view that precision medicine methods provide an opportunity to enhance clinical decision-making by integrating improvements in biological measurements, computational power, and connectivity. Their article reimagines precision medicine beyond “big data” and “deep learning,” describing the need to develop infrastructure and health systems that can optimize its clinical potential.

Quetiapine activates intestinal PXR signaling to increase hyperlipidemia in mice
Quetiapine is an atypical antipsychotic that is com-monly prescribed to treat several psychiatric conditions, including bipolar disorders, schizophrenia, major depres-sive disorder, and general anxiety disorder. Quetiapine is efficacious as a long-term treatment for these disorders and has a reduced risk of drug-induced movement disorders
compared with other antipsychotic drugs. Unfortunately, long-term users of que-tiapine are at increased risk of cardiovascular disease (CVD) as a consequence of hyperlipidemia; however, it is not clear how this drug promotes lipid dysfunc-tion. In this issue, Zhaojie Meng and colleagues investigate the role of pregnane X receptor (PXR), which is an important regulator of lipid homeostasis, in que-tiapine-induced dyslipidemia. The authors show that quetiapine activates PXP in the intestine, as mice lacking intestinal PXR were protected from quetiapine-induced dyslipidemia. Quetiapine-induced PXR activation was shown to stimu-late the intestinal expression of cholesterol transporter NPC1L1 and microsomal triglyceride transfer protein (MTP), leading to increased intestinal lipid absorp-tion. Moreover, treatment of murine enteroids and human intestinal cells with quetiapine promoted PXR-associated gene expression and cholesterol uptake. Together, the results reveal that adverse effects of quetiapine are mediated by PXR activation. The cover image shows the accumulation of lipid droplets in an H&E-stained intestine section from a quetiapine-treated mouse.

Obesity-associated mutation linked to aberrant neurodevelopment
Omega-3 fatty acids ameliorate Fusobacterium nucleatum–induced placental inflammation
metabolism
microbiology
Intronic polymorphisms in α-ketoglutarate–dependent dioxygenase (FTO) are linked to obesity and alter regulation of the nearby ciliary gene RPGRIP1L. In mice, global Rpgrip1l deletion is embryonic lethal; however, POMC neuron–specific Rpgrip1l deletion increases food intake, leading to obesity. Liheng Wang and colleagues have now shown that RPGRIP1L depletion–associated obesity and hyperphagia phenotypes are due to neurode-velopmental defects, including a reduced ratio of POMC to NPY neurons and increased arcuate nucleus (ARH) axonal projections to the paraven-
tricular nucleus. Moreover, neurons derived from human induced pluripotent stem cells (iPSCs) with reduced RPGRIP1L had reduced ciliogenesis (see the accompanying image) and decreased responsive-ness to neurospecification signals. ARH-like neurons derived from FTO obesity risk allele–harboring embryonic stem cells had decreased RPGRIP1L expression and reduced numbers of POMC neurons. In contrast, RPGRIP1L overexpression increased POMC neuron number. These results demonstrate that RPGRIP1L is required for appropriate development of ARH neurons.

Intrauterine infection, particularly with the oral anaerobe Fusobacterium nucleatum, during pregnancy is a prevalent cause of adverse outcomes, including preterm birth and neonatal sepsis. Jeewon Garcia-So and colleagues determined that F. nucleatum activates TLR4 on maternal endothelial cells, thereby triggering placental inflammation. Placental inflammation led to a coordinated inflammatory response, characterized by initiation of NF-κB signaling in maternal endothelial cells, followed by NF-κB signaling in the surrounding cells, leading to proinflammatory effector expression. Administration of omega-3 fatty acids to pregnant mice prior to F. nucleatum infection markedly reduced placental inflammation, decreased
bacterial burden, and improved fetal outcomes. This study suggests that omega-3 fatty acid supplementation should be further explored for improving adverse pregnancy outcomes.

Isoquercetin reduces coagulation markers in patients at risk of thrombosisThe release of protein disulfide isomerase (PDI) from cells during disease or in response to injury has been shown to exacerbate pathological processes, including thromboembolism and, as such, is currently being explored as a therapeutic target. Jeffrey Zwicker and colleagues report on the results of a multicenter phase II trial of the PDI-targeting flavonoid isoquercetin in cancer patients at high risk of thrombosis. One cohort received 500 mg isoquercetin per day, while a second cohort was given a daily 1000-mg dose. Thromboem-bolism and major hemorrhagic events did not occur in either cohort. Isoquercetin inhibited PDI activity in plasma and decreased platelet-dependent thrombin generation in a dose-dependent manner. At the higher dose, isoquercetin reduced levels of D-dimer and P selectin in circulation. The noted reduction in coagulation markers supports further evaluation of isoquercetin in patients at risk of thrombosis.

Baseline immunotypes predict type 1 diabetes progression and treatment responseβ Cell function declines at variable rates among individuals newly diagnosed with type 1 diabetes (T1D), though factors that determine this heterogeneity are poorly defined. Matthew Dufort and colleagues analyzed β cell function and performed RNA-Seq on individuals with new-onset T1D and identified age-depen-dent immunotypes associated with disease progression. Young patients with high B cell and low neutrophil levels at diagnosis lost insulin secretion at a rapid rate, while those with high neutrophil levels at diagnosis exhibited slow progression. In a second study, Peter Linsley and colleagues identified the same immunotypes in an evaluation of the response of patients newly diagnosed with T1D to abatacept. At baseline, both abatacept- and placebo-treated groups exhibited similar immunotypes as those identified by Dufort and colleagues, and exhibited an age-related link between baseline immunotype and disease progression. Moreover, patients who were resistant to abatacept expressed a unique

Identification of intratumor heterogeneity of immune response pathway expressionHeterogeneity within tumors has been linked to the variable responses of a variety of cancers to immunotherapy. A better understanding of the effects of this heterogeneity on outcome and treatment response will be essential to improve cancer treatment. Ke-Yue Ma and colleagues used single-cell RNA-Seq data from lung adenocarcinoma patients and cell lines to evaluate the intratumoral heterogeneity of the immune response. IFN-γ pathway genes in particular were expressed variably in single cancer cells, and downregulation of IFN-γ–mediated genes in cell lines was associated with acquisition of resistance. Moreover, expression of tumor-restricted antigens was variable between cells. Together, these results reveal a high level of intratumor heterogeneity and indicate that multifactorial approaches will be essential to prevent tumor escape and treatment resistance.

Metabolic switch to ketone body utilization is protective in heart failure
Adrenergic stimulation after Kawasaki disease vasculitis induces myocardial fibrosis
cardiology
Kawasaki disease (KD) is an acute illness that primarily affects children, and is characterized by systemic vascular inflammation and fever; it can progress to coronary artery abnormalities, aneurysms, myocarditis, and myocardial dysfunction. KD is also known to lead to long-term cardiac remodeling that can persist into adulthood, increasing the risk of cardiovascular complica-tions, including myocardial fibrosis. Using a murine model of KD, Harry Matundan, Jon Sin, and colleagues determined that adrenergic stimulation after establishment of KD vasculitis increases cardiac hypertrophy and myocardial fibrosis (see the accompanying image) and reduces ejection fraction. These findings were linked to IL-1β signaling and reduced endothelial CD31 expression, a marker of capillary rarefication. This study identifies a link between adrenergic stimulation after KD and the development of myocardial fibrosis. Additional longitudinal studies are needed to study the relevance of these experimental observations to KD patients.

Energy utilization in the heart is optimized for specific developmental time points and is flexible to accommodate variability in fuel source. Recent metabolic profiling of hypertrophied and failing hearts indicates a shift toward ketone body oxidation in response to a reduced capacity for fatty acid oxidation; however, it is not clear whether this metabolic shift is adaptive or destructive. Julie Horton and colleagues generated mice that are unable to oxidize the ketone body 3-hydroxybutyrate (3OHB) in the heart and determined that these mice develop exacerbated heart failure compared with WT animals. Moreover, delivery of exogenous 3OHB reduced cardiac dysfunction and ameliorated pathological remodeling in a canine model of progressive heart failure. Lastly, 3OHB induced enhance-
ment of mitochondrial thermodynamics under fatty acid–limiting conditions. Together, these results indicate that the 3OHB utilization is a protective metabolic response that should be further explored for limiting damage in heart failure.
