We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Transcriptional Control of Tissue-Resident Memory T Cell Generation
Transcriptional control of tissue-resident memory T cell generation Filip Cvetkovski Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2019 © 2019 Filip Cvetkovski All rights reserved ABSTRACT Transcriptional control of tissue-resident memory T cell generation Filip Cvetkovski Tissue-resident memory T cells (TRM) are a non-circulating subset of memory that are maintained at sites of pathogen entry and mediate optimal protection against reinfection. Lung TRM can be generated in response to respiratory infection or vaccination, however, the molecular pathways involved in CD4+TRM establishment have not been defined. Here, we performed transcriptional profiling of influenza-specific lung CD4+TRM following influenza infection to identify pathways implicated in CD4+TRM generation and homeostasis. Lung CD4+TRM displayed a unique transcriptional profile distinct from spleen memory, including up-regulation of a gene network induced by the transcription factor IRF4, a known regulator of effector T cell differentiation. In addition, the gene expression profile of lung CD4+TRM was enriched in gene sets previously described in tissue-resident regulatory T cells. Up-regulation of immunomodulatory molecules such as CTLA-4, PD-1, and ICOS, suggested a potential regulatory role for CD4+TRM in tissues. Using loss-of-function genetic experiments in mice, we demonstrate that IRF4 is required for the generation of lung-localized pathogen-specific effector CD4+T cells during acute influenza infection. Influenza-specific IRF4−/− T cells failed to fully express CD44, and maintained high levels of CD62L compared to wild type, suggesting a defect in complete differentiation into lung-tropic effector T cells. -

Non-coding Functional SNPs within the Arthritis-associated TRAF1-C5 Locus Darren Jianjhih Chiu A Thesis Submitted to the Faculty of The Harvard Medical School in Partial Fulfillment of the Requirements for the Degree of Master of Medical Sciences in Immunology Harvard University Boston, Massachusetts. May, 2018 Thesis Advisor: Dr. Peter Nigrovic Darren Jianjhih Chiu! Non-coding functional SNPs within the arthritis-associated TRAF1-C5 locus Abstract The TRAF1-C5 locus is associated by genome-wide association studies (GWAS) with susceptibility to rheumatoid arthritis and juvenile idiopathic arthritis. Monocytes from healthy individuals with the arthritis-associated risk variant rs3761847 express lower intracellular TRAF1 protein in response to LPS and have greater LPS-induced production of IL-6 and TNF, consistent with a role in inflammatory disease. However, the functional interpretation of this finding remains challenging. Tagging SNPs identified by GWAS are often not causal themselves, but rather simply reside in close association with true functional variants. -

Summary The TGFb family member NODAL, primarily known for its role during embryonic development, has also been associated with tumor progression in a number of cancers. Some of the evidence supporting its involvement in melanoma has appeared contradictory, suggesting that NODAL in this context might rely on a non-canonical mode of signaling. To investigate this possibility we studied how a deletion of NODAL affected cell behavior in a metastatic melanoma cell line. The mutation does prevent melanoma cells from acquiring an invasive behavior. -

In the current study, a fortuitous observation in transgenic mice globally overexpressing heparanase (hep-tg) was the discovery of improved glucose homeostasis. We examined the mechanisms that contribute towards this improved glucose metabolism. Heparanase overexpression was associated with enhanced GSIS and hyperglucagonemia, in addition to changes in islet composition and structure.
