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.

View SamplesThe R47H variant of TREM2 is associated with higher risk of Alzheimer's disease. We generated mice expressing the common variant or R47H variant of human TREM2
Humanized TREM2 mice reveal microglia-intrinsic and -extrinsic effects of R47H polymorphism.

View SamplesILC3 contain 3 well-defined subsets, CCR6+ ILC3, NKp46+ ILC3, and CCR6NKp46 DN ILC3. These subsets had not previously been transcriptionally compared and the extent to which they had shared or unique transcriptional profiles remained unclear.
IL-15 sustains IL-7R-independent ILC2 and ILC3 development.

TREM2 sustains microglial expansion during aging and response to demyelination.

View SamplesMurine GVH-SSc dorsal scapular skin samples were analyzed to determine the effect of IFNAR-1 inhibition on gene expression at day 14 and day 28. Gene expression in GVH-SSc skin from mice treated with a neutralizing IFNAR-1 antibody was compared to that in GVH-SSc skin from mice treated with isotype IgG, with skin from syngeneic graft controls as reference.

View SamplesLymphocytes are adversely affected during sepsis. Some CD4+ splenocytes undergo apoptosis while others become Th2 polarized. The molecular determinants of these phenotypic changes are not known. Here we compare the transcriptional response of septic CD4 splenocytes to CD4 splenocytes from sham-manipulated animals 6h after sepsis and identify an early transcriptional component to the septic CD4+ splenocyte phenotype.
Splenic CD4+ T cells have a distinct transcriptional response six hours after the onset of sepsis.

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.
