Gene Co-Expression Networks Analysis Reveal Novel Molecular Endotypes In Alpha-1 Antitrypsin Deficiency, Jen-Hwa Chu, Wenlan Zang
Gene Co-Expression Networks Analysis Reveal Novel Molecular Endotypes In Alpha-1 Antitrypsin Deficiency, Jen-Hwa Chu, Wenlan Zang
Yale Day of Data
Rationale:Alpha-1 antitrypsin deficiency (AATD) is a genetic condition that predisposes to early onset pulmonary emphysema and airways obstruction. The exact mechanism through which AATD leads to lung disease is incompletely understood.
Objectives: To investigate the effect of AAT genotype and augmentation therapy on bronchoalveolar lavage (BAL) and peripheral blood mononuclear cells (PBMC) transcriptome, while examining the link between gene expression profiles, and clinical features of AATD.
Methods: We performed RNA-Seq on RNA extracted from BAL and PBMC on samples obtained from 89 AATD patients enrolled in the Genomic Research in Alpha-1 Antitrypsin Deficiency and Sarcoidosis (GRADS) study. Differential …
Non-Invasive Analysis Of The Sputum Transcriptome Discriminates Clinical Phenotypes Of Asthma, Xiting Yan
Non-Invasive Analysis Of The Sputum Transcriptome Discriminates Clinical Phenotypes Of Asthma, Xiting Yan
Yale Day of Data
Whole transcriptome wide gene expression profiles in the sputum and circulation from 100 asthma patients were measured using the Affymetrix HuGene 1.0ST arrays. Unsupervised clustering analysis based on pathways from KEGG were used to identify TEA clusters of patients from the sputum gene expression profiles. The identified TEA clusters have significantly different pre-bronchodilator FEV1, bronchodilator responsiveness, exhaled nitric oxide levels, history of hospitalization for asthma and history of intubation. Evaluation of TEA clusters in children from Asthma BRIDGE cohort confirmed the identified differences in intubation and hospitalization. Furthermore, evaluation of the TH2 gene signatures suggested a much lower prevalence of …

This poster illustrates the differences between the IPF disease-specific variety of lung macrophages and the two varieties of macrophages known to reside in the normal human lung.

Discovering The Immune Cell Landscape In Ipf By Whole Lung Single Cell Transcriptomics, Jonas C. Schupp, Taylor Adams
Yale Day of Data
Single cell transcriptomes of 27 IPF, 13 COPD and 14 control lungs were established. Cells were clustered into major cell types, then the immune cells consisting of 116,057 myeloid, 4,742 B-, and 19,165 T-& NK-cells were analyzed and subclustered. Subclustering revealed IPF-associated unique gene expression profiles subpopulations that were specific to the IPF lung. For example, we could identify an IPF-specific macrophage subpopulation which showed a pro-fibrotic profile characterized by SPP1, CHIT1, CCL18, SPARC, LGMN, CTSK, and MMP9 gene expression. Antagonistically, NK- and cytotoxic T-cells revealed a significantly increased expression of the protease inhibitors A2M and PZP in the IPF …
