Association of Soluble ST2 With Functional Outcome, Perihematomal Edema, and Immune Response After Intraparenchymal Hemorrhage
This manuscript builds on the Kimberly Lab’s work that highlights the role of the interleukin-33/ST2 pathway and its link to post-stroke inflammation and brain edema. The lab had previously shown that this inflammatory signaling cascade is associated with brain edema and activation of innate immunity after ischemic stroke and subarachnoid hemorrhage. This paper extends previous work to show a similarly damaging activation after intracerebral hemorrhage. Collectively, this work highlights that modulation of the IL-33/ST2 pathway is a candidate target to reduce the severity of edema and inflammation after all major forms of acute brain injury.

Uridine and RNA as energy
To identify genes and pathways that cells can use to survive when glucose — an important source of energy and carbon — is limited, Vamsi Mootha, and colleagues performed genome-wide genetic screens and a PRISM growth assay. They found that cells ranging from healthy immune cells to cancer cells can use uridine, a component of RNA, as an energy source when glucose is unavailable. Targeting the biochemical pathway that cells use to break down uridine-derived sugar could help treat cancers and metabolic disorders and tune the immune response.

Clonal haematopoiesis and risk of chronic liver disease.
Through advances in population-based genomic sequencing an analysis, the Natarajan lab and others showed that ‘clonal hematopoiesis of indeterminate potential’ (CHIP) is a surprisingly common feature as we age. They also showed that CHIP plays a role in coronary artery disease, the leading contributor to death in the US and now globally. As inflammation appeared to be a principal driver, the Natarajan lab has since then attempted to understand whether CHIP plays a role in other conditions where inflammation has been invoked as a key driver. This study focused on chronic liver disease because, which has become increasingly common with the rising prevalence of obesity and metabolic syndrome. However, therapeutic options for chronic liver disease have remained limited for decades except for hepatitis C. Fatty liver disease is increasingly recognized but the reasons by inflammation and downstream liver disease occur remain limited. They therefore hypothesized that CHIP could play a role. It was found that CHIP offered to confer a relatively large risk for chronic liver disease, sometimes larger than currently recognized risk factors. And causal inference approaches, such as Mendelian randomization, supported a potential causal relationship. Liver MRIs and liver biopsies were consistent with greater steatohepatitis and not greater steatosis. Murine models similarly showed greater steatohepatitis without greater steatosis, and also greater fibrosis when followed for longer periods of time. Genetic deficiency of the NLRP3 inflammasome appeared to ameliorate this phenotype in the mice. This inflammatory pathway has also been invoked in CHIP-associated coronary artery disease. The relationship between CHIP and liver disease was previously unknown. These observations highlight a new potential precision medicine paradigm for chronic liver disease prevention. The findings support the scientific premise that, particularly for TET2 CHIP, inhibition of the NLRP3 inflammasome may reduce the risk of chronic liver disease.

Nucleosides Associated With Incident Ischemic Stroke in the REGARDS and JHS Cohorts
This manuscript is the first to show a link between specific nucleoside metabolites and the risk of future stroke, independent of traditional stroke risk factors. In this study, CGM Investigator Taylor Kimberly and colleagues also sought to determine whether these candidates were a reflection of genes or environment through GWA studies. Their findings suggest that the top metabolites were related to environmental or behavioral patterns, ultimately leading our group to focus on potential links between diet, the gut microbiome, and stroke risk.

Brain-specific deletion of GIT1 impairs cognition and alters phosphorylation of synaptic protein networks implicated in schizophrenia susceptibility
The molecular and cellular basis of cognitive deficits in schizophrenia remains poorly understood. Recent progress in elucidating the genetic architecture of schizophrenia has highlighted the association of multiple loci and rare variants that may impact susceptibility. A critical next step is to delineate specifically how such genetic variation impacts synaptic plasticity and to determine if and how the encoded proteins interact biochemically. Towards this goal, CGM Investigator Steve Haggarty and colleagues studied the roles of GPCR-kinase interacting protein 1 (GIT1), a synaptic scaffolding protein with damaging coding variants found in schizophrenia patients, as well as copy number variants found in patients with neurodevelopmental disorders. Profiling GIT1 knockout mice revealed memory deficits and reduced cortical dendritic spine density. Using global quantitative phospho-proteomics, we revealed that GIT1 deletion perturbs specific networks of synaptic proteins, suggesting that GIT1 regulates the phosphorylation of critical regulators of neuroplasticity.

Distinct effects of interleukin-6 and interferon-γ on differentiating human cortical neurons
The Karmacharya lab interrogated neurodevelopmental effects of exposure to interleukin-6 (IL-6) and interferon-γ (IFN-γ) in differentiating human cortical neurons. Transcriptomic analyses showed IL-6 exposure affected genes regulating extracellular matrix, actin cytoskeleton and TGF-β signaling while IFN-γ exposure impacted genes regulating antigen processing, major histocompatibility complex and endoplasmic reticulum biology. IL-6 altered mitochondrial respiration in the differentiated neurons while IFN-γ induced reduction in dendritic spine density. Pretreatment with folic acid ameliorated IL-6 effects on mitochondrial respiration and IFN-γ effects on dendritic spine density. These findings suggest cellular processes that mediate maternal immune activation in developing brains and how folic acid mitigates such risk.

Our research seeks to understand the drivers of both mental illness and mental wellbeing across the lifespan. Much of our work has focused on the social and biological underpinnings of depression and anxiety among women, children, adolescents, and other vulnerable populations, including racial/ethnic minorities and people of low socioeconomic status.
We study a range of biological factors and processes contributing to mental health—including the role of genetic variation and epigenetic mechanisms—as well as biological markers of future risk, such as markers captured in children’s primary (or baby) teeth.
We study multiple social factors, including the role of early life environmental exposures and stressors such as childhood adversity, on mental health.
