A mouse model of HIES reveals pro and anti-inflammatory functions of STAT3

ABSTRACT: Mutations of STAT3 underlie the autosomal dominant form of hyper-immunoglobulin E syndrome (HIES). STAT3 has critical roles in immune cells and thus, hematopoietic stem cell transplantation (HSCT), might be a reasonable therapeutic strategy in this disease. However, STAT3 also has critical functions in non-hematopoietic cells and dissecting the protean roles of STAT3 is limited by the lethality associated with germline deletion of Stat3. Thus, predicting the efficacy of HSCT for HIES is difficult. To begin to dissect the importance of STAT3 in hematopoietic and non-hematopoietic cells as it relates to HIES, we generated a mouse model of this disease. We found that these transgenic mice recapitulate multiple aspects of HIES, including elevated serum IgE and failure to generate Th17 cells. We found that these mice were susceptible to bacterial infection that was partially corrected by HSCT using wild type bone marrow, emphasizing the role played by the epithelium in the pathophysiology of HIES.

Genome-wide transcriptome analysis in PBMCs of HIES patient A.II.1 compared to healthy sibling A.II.5

Project description:Signal-transducer-and-activator-of-transcription-3 (STAT3) is a central regulator of immune homeostasis. STAT3 levels are strictly controlled and STAT3 impairment contributes to several diseases including the monogenic autosomal-dominant hyper-IgE syndrome (AD-HIES). We investigated patients of four consanguineous families with an autosomal-recessive disorder resembling the phenotype of AD-HIES, with symptoms of immunodeficiency, recurrent infections, skeletal abnormalities, and elevated IgE. Patients presented with reduced STAT3 expression and diminished Th17 cell numbers, in absence of STAT3 mutations. We identified homozygous nonsense mutations in ZNF341, encoding a zinc-finger transcription factor. Wildtype-ZNF341 bound to and activated the STAT3 promoter, whereas the mutant variants showed impaired transcriptional activation, partly due to nuclear translocation failure. In summary, nonsense mutations in ZNF341 account for the STAT3-like phenotype in four autosomal-recessive kindreds. Thus, ZNF341 is a previously unrecognized regulator of immune homeostasis.

Gene expression analysis in endothelial cells derived from patients with Autosomal-dominant hyper-IgE syndrome (AD-HIES)

Project description:Autosomal-dominant hyper-IgE syndrome (AD-HIES, Job’s syndrome) is a primary immunodeficiency caused by loss of function mutations in signal transducer and activator of transcription 3 (STAT3), a critical regulator of diverse cellular processes. In addition to immunological deficits, patients experience severe non-immunological features including skeletal, connective tissue and vascular abnormalities, poor post-infection healing, and subsequent pulmonary failure. The underlying mechanisms of these STAT3-dependent non-immunological features are not understood, preventing the development of targeted treatments. In this study, global gene expression was analysed in the patients umbilical vein endothelial cells in order to identify signaling pathway affected by the disease-causing STAT3 mutations with ultimate goal to better understand the disease mechanism and identify promising therapeutic targets.

A recessive form of hyper-IgE syndrome by disruption of ZNF341-dependent STAT3 transcription and activity

Project description:Heterozygosity for human STAT3 dominant-negative (DN) mutations underlies an autosomal dominant form of hyper-IgE syndrome (HIES). We describe patients with an autosomal recessive form of HIES due to loss-of-function mutations of a previously uncharacterized gene, ZNF341. ZNF341 is a transcription factor that resides in the nucleus, where it binds a specific DNA motif present in various genes, including, most notably the STAT3 promoter. The patients’ cells have low basal levels of STAT3 mRNA and protein. The auto-induction of STAT3 production, activation, and function by STAT3-activating cytokines is particularly strongly impaired. Like patients with STAT3 DN mutations, ZNF341-deficient patients lack Th17 cells, have an excess of Th2 cells, and low memory B cells, due to the tight dependence of STAT3 activity on ZNF341 in lymphocytes. Their milder extra-hematopoietic manifestations and stronger inflammatory responses reflect the lower ZNF341-dependence of STAT3 activity in other cell types. Human ZNF341 is essential for the STAT3 transcription-dependent auto-induction and sustained activity of STAT3.

Next Generation Sequencing Facilitates Quantitative Analysis of mRNA expression of STAT3 deficiency skin

Project description:Dominant-negative mutations of signal transducer and activator of transcription 3 (STAT3) signaling which controls epithelial proliferation in various tissues, leads to atopic dermatitis (AD) in hyper IgE syndrome (HIES).

Single-cell multi-omics sequencing reveals the functional regulatory landscape of STAT3-V637M Hyper-IgE syndrome

Project description:Hyper-IgE syndrome (HIES) is a primary immunodeficiency characterized by, among others, the excessive production of IgE and repetitive bacterial/fungal infections. Although STAT3 is a known causative factor of HIES, the biological consequences of STAT3 mutation are not completely understood, especially at the epigenetic level. Here, we used multi-omic approaches to decipher the multidimensional immune disturbance in a male HIES patient harboring STAT3-V637M. In his peripheral blood mononuclear cell (PBMC) we found significant clonal expansion of CD8 T cells (whose expression of CD8 subunits was increased, resulting in enhanced responsiveness to MHC I molecules), but not CD4 T cells and B cells in his. The lack of T cells-B cells interaction could be responsible for the limited number of his B cells, although they exhibited a higher potential in producing immunoglobulin, elevated SPIC binding might bias this process toward IgE isotype production. Immune checkpoint inhibitors, including CTLA4, LAG3, were overexpressed in his PBMC-CD4 T cells, accompanied by reduced CD28 and IL6ST (gp130) expression. For his CD4 T cells, integrative analyses predicted upstream transcription factors (ETV6, KLF13, and RORA) for LAG3, IL6ST, and CD28, respectively. The down-regulated phagocytic, and nitric oxide synthetic genes in his PBMC-monocytes seem to be the culprit of his disseminated bacterial/fungal infection. In his bronchoalveolar lavage fluid (BALF), we identified two macrophages with anti-bacterial properties, which were characterized by CXCL8/S100A8/S100A9, or SOD2, respectively. Together, this study comprehensively described how the immune cell landscape was disturbed in STAT3-V637M HIES and provided a resource for further studies on STAT3 biology.

STAT3 binding to DNA in wildtype vs B cell specific STAT3 knockout mice

Project description:A mutation in the Signal Transducer and Activator of Transcription 3 (STAT3) has been linked to incidence of Autosomal Dominant Hyper Immunoglobulin E Syndrome (AD-HIES), a disease characterized by elevated serum IgE antibody. However, how this genetic mutation leads to the phenotype has not been fully understood. We investigated the specific role of STAT3 in the germinal center (GC) B cells and plasma cells for IgE class switching. Through the use of STAT3 conditional knockout mice in a Th2-type immunization model, we demonstrated that CD2-Cre driven STAT3 cKO mice showed elevated IgE and decreased IgG1 in the serum, and a reduction in GC formation. Within the GC, IgG1+ GC B cells were decreased while IgE+ GC B cells were more prevalent. Additionally, these mice exhibited reduced IgG1 and elevated IgE populations of antibody-producing plasma cells. Subsequent experiments using a CD19-Cre B-cell specific cKO mouse established this effect to be B-cell intrinsic. Transcription factors critical for GC and plasma cell differentiation, including Bcl-6 and Aicda, were shown to function as downstream signals of STAT3 regulation. Further ChIP-seq analysis revealed that many genes including Bcl3 and Crtc2 were among the direct STAT3 regulated targets. Mice with STAT3 deficiency in B cells also demonstrated an increase in lung inflammation when used in an asthma-like disease model. This model suggests a negative role for STAT3 in regulating class switching of the GC B cells from the IgG1 to the IgE producing state, which may serve as a therapeutic target for treatment of AD-HIES and other immune disorders.
