Journal ArticleDOI
Monocyte and bone marrow macrophage transcriptional phenotypes in systemic juvenile idiopathic arthritis reveal TRIM8 as a mediator of IFN-γ hyper-responsiveness and risk for macrophage activation syndrome
Grant S. Schulert,Grant S. Schulert,Alex V. Pickering,Thuy Do,Sanjeev Dhakal,Ndate Fall,Daniel Schnell,Mario Medvedovic,Nathan Salomonis,Nathan Salomonis,Sherry Thornton,Sherry Thornton,Alexei A. Grom,Alexei A. Grom +13 more
TL;DR: TRIM8 is also upregulated in SJIA monocytes, and augments macrophage IFN-γ response in vitro, providing both a candidate molecular mechanism and potential therapeutic target for monocyte hyper-responsiveness to IFNγ in cytokine storms including MAS.
Journal ArticleDOI
Proceedings from the 2 nd Next Gen Therapies for Systemic Juvenile Idiopathic Arthritis and Macrophage Activation Syndrome symposium held on October 3-4, 2019.

TL;DR: A meeting to integrate clinical and research findings in MAS and SJIA-LD brought together scientists, clinicians, parents and FDA representatives with the objectives to develop a shared understanding of this seemingly new pulmonary complication of SJIA.
Journal ArticleDOI
Distinct gene expression signatures characterize strong clinical responders vs non‐responders to Canakinumab in children with sJIA
Emely L Verweyen,Alex V. Pickering,Alexei A. Grom,Alexei A. Grom,Grant S. Schulert,Grant S. Schulert +5 more
TL;DR: In this paper, a secondary analysis of whole-blood gene expression microarrays using blood samples obtained from healthy controls and systemic juvenile idiopathic arthritis (JIA) patients at baseline and on day 3 after canakinumab treatment (GEO accession no. GSE80060).
Proceedings ArticleDOI
Cross-modal representation alignment of molecular structure and perturbation-induced transcriptional profiles.
TL;DR: This work proposes a new cross-modal small molecule retrieval task, designed to force a model to learn to associate the structure of a small molecule with the transcriptional change it induces, developed formally as multi-view alignment problem, and presents a coordinated deep learning approach.

Approaching Small Molecule Prioritization as a Cross-Modal Information Retrieval Task through Coordinated Representation Learning.
Samuel G. Finlayson,Matthew B. A. McDermott,Alex V. Pickering,Scott Lipnick,William Yuan,Isaac S. Kohane +5 more
TL;DR: A novel deep learning architecture is utilized to jointly train coordinated embeddings of chemical structures and transcriptional signatures by training neural networks in a coordinated manner such that learned chemical representations correlate most highly with the encodings of the transcriptional patterns they induce.
