Distinct Gene Regulatory Pathways for Human Innate versus Adaptive Lymphoid Cells.
Specimen part
View SamplesInnate lymphoid cells (ILCs) serve as sentinels in mucosal tissues, sensing release of soluble inflammatory mediators, rapidly communicating danger via cytokine secretion, and functioning as guardians of tissue homeostasis. Although ILCs have been studied extensively in model organisms, little is known about these first responders in humans, especially their lineage and functional kinships to cytokine-secreting T helper cell (Th) counterparts. Here, we report gene regulatory circuitries for four human ILCTh counterparts derived from mucosal environments, revealing that each ILC subset diverges as a distinct lineage from Th and circulating natural killer cells, but shares circuitry devoted to functional polarization with their Th counterparts. Super-enhancers demarcate cohorts of cell identity genes in each lineage, uncovering new modes of regulation for signature cytokines, novel molecules that likely impart important functions to ILCs, and potential mechanisms for autoimmune disease SNP associations within ILCTh subsets.

SMAD4 impedes the conversion of NK cells into ILC1-like cells by curtailing non-canonical TGF-β signaling.
Specimen part
View SamplesAmong the features that distinguish type 1 innate lymphoid cells (ILC1s) from NK cells is a gene signature indicative of TGFb-family cytokine imprinting. To assess the impact of TGFb family cytokines on ILC1 differentation, we examined SMAD4- a transcription factor that facilitates the signaling pathway common to all TGFb family cytokines-was specifically ablated in ILCs and NK cells. While SMAD4 deficiency did not affect ILC1 differentation, NK cells paradoxically aquired an ILC1-like gene signature and were incapable of controlling tumor metastasis and viral infection.

View SamplesSenescent human fibroblasts were compared to young proliferating fibroblasts. Five different cell lines were compared. Illumina sequencing (HiSeq2000) was applied to generate 50bp single-end reads. Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de) Overall design: 48 samples: 3 biological replicates for each group: young proliferating and senescent BJ cells; young proliferating and senescent Wi-38 cells; young proliferating and senescent IMR-90 cells; 5 population doubling from young proliferating to senescent cell for HFF and MRC-5 cells
