Affymetrix Human Genome U133A Array (hgu133a)
Description
Lysosome-related organelles have versatile functions including protein and lipid degradation, signal transduction, and protein secretion. The molecular elucidation of rare congenital diseases affecting endosomal/lysosomal biogenesis has given insights into physiological functions of the innate and adaptive immune system.. Here, we describe a novel human primary immunodeficiency disorder and provide evidence that the endosomal adaptor protein p14, previously characterized as confining mitogen-activated-protein-kinase (MAPK) signaling to late endosomes, is critical for the function of neutrophils, B-cells, cytotoxic T-cells and melanocytes. Combining genetic linkage studies and transcriptional profiling analysis, we identified a homozygous point mutation in the 3 UTR of p14 (also known as MAPBPIP), resulting in decreased protein expression. In p14-deficient cells, the distribution of late endosomes was severely perturbed, suggesting a novel role for p14 in endosomal biogenesis. These findings have implications for understanding endosomal membrane dynamics, compartmentalization of cell signal cascades, and their role in immunity.

Hyper IgE Recurrent Infection Syndrome (HIES or Jobs syndrome), is a rare disorder of immunity and connective tissue, typically manifest with boils, cyst-forming pneumonias, and extremely elevated serum IgE as well as retained primary dentition and bone abnormalities. Inheritance can be autosomal dominant.

- Affymetrix Human Gene 2.0 ST Array (hugene20st)
Description
Ascertain the effects of disease-causing gene mutations on the differentiation status of human nave CD4+ T cells in the setting of primary immunodeficiencies. Thus, do CD4+ T cells isolated according to a nave surface phenotype (ie CD4+CD45RA+CCR7+) from healthy donors exhibit a similar gene expression profile as phenotpyically-matched cells isolated from individuals with defined primary immunodeficiencies caused by specific monogenic mutations.
Publication Title
Unique and shared signaling pathways cooperate to regulate the differentiation of human CD4+ T cells into distinct effector subsets.

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.

Description
This analysis represents the first comprehensive sampling of germ cells in the developing testis over time, at high-resolution, single-cell depth. From these analyses, we have not only revealed novel genetic regulatory signatures of murine germ cells over time, but have also demonstrated that cell types positive for a single marker gene have the capacity to change dramatically during testis maturation, and therefore cells of a particular “identity” may differ significantly from postnatal to adult life. Overall design: Single-cell suspensions of mammalian testes ranging from PND6 to adult were processed for single-cell RNAseq (10x Genomics Chromium) and libraries were sequenced on a NextSeq500 (Illumina).

Description
Neonates are intrinsically defective at creating memory CD8+ T cells in response to infection with intracellular pathogens. Here we investigated differential of small RNAs, transcription factors, and chemokine receptors regulation in neonates as compared to adults before and during infection. We found that prior to infection, na誰ve cells have a different expression profile for many microRNAs, and gene targets of these microRNAs show widespread expression differences. These targets and other changes in gene expression in na誰ve cells result in neonatal cells that get activated more easily, express chemokine receptors that home to sites of infection, and are less protected from apoptosis during contraction. As a result, changes in neonatal na誰ve cells drive effector cell terminal differentiation at the expense of creating long-lived memory cells. Overall design: total RNAs were sequenced from adult and neonatal CD8+ T cells before and during infection

Description
Here, we characterized the transcriptome of MCs under steady state, immunoglobulin E (IgE)-sensitized and anti-IgE-treated conditions. Overall design: MCs were left untreated or sensitized overnight with myeloma-IgE (0.5 µg/ml) and treated with anti-IgE (1 µg/ml) for 2h. RNA was isolated with Trizol and RNeasy columns and RNA-seq was performed.

Description
Stroke is a leading cause of adult disability and death. Inflammation plays an important role in stroke pathology, but the factors which promote brain inflammation in this setting remain to be fully defined. Here we investigate the meninges, the membranes that envelop the brain, for a potential role in modulating immune cell trafficking to the brain. We also investigate the potential of mast cells (MCs) to modulate this response as MCs are often considered as 'first responders' playing a critical role in the initiation and development of inflammation in many disease settings. We find that stroke increases expression of inflammatory and immune response genes in the meninges in mice consistent with a potential role in modulating immune cell trafficking. Moreover, genetic and cell transfer approaches identify MCs as important modulators of this response.
