Description
Uterine macrophages are thought to play an important regulatory role at the maternal-fetal interface. We report here a unique gene expression pattern intrinsic of first trimester decidual monocytes/macrophages, but not of their blood counterparts. The micro-array data comprises approximately 14,000 genes. Some of the key findings were confirmed by real time PCR or secreted protein measurements. A large number of regulated genes were found to be functionally related to immunomodulation and tissue remodelling, corroborating polarization patterns of differentiated macrophages of M2 phenotype. These include M2 markers such as CCL-18, CD209, insulin-like growth factor (IGF)-1, mannose receptor c type (MRC)-1 and fibronectin-1. Further, the selective up-regulation of triggering receptor expressed on myeloid cells (TREM)-2, alpha-2-macroglobulin (A2M) and prostaglandin D2 synthase (PGDS) provides new insights into the regulatory function of decidual macrophages in pregnancy. In addition, a large number of regulated genes in the micro-array analysis were related to cell cycle regulation. Taken together, molecular characterization of decidual macrophages presents a unique transcriptional profile replete with important components for fetal immunoprotection.

Description
We report the transcriptome analysis of epidermal CD8 tissue resident memory T (TRM) cells from healthy human skin. Specifically, epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells from healthy human skin were sorted by FACS. Differential gene expression analysis revealed functional dichotomy of epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- TRM cells. Overall design: Analysis of differentially expressed genes between epidermal CD8+CD103+CD49a+ and CD8+CD103+CD49- T cells from healthy human skin, biological replicates (n=7) (healthy skin donors).

Description
We apply RNA-seq to limited populations of Innate Lymphoid Cells type 2 and type 3 (ILC2s and ILC3s, respectively) in human individuals infected with acute HIV in the FRESH study. We measured the whole transcriptome of ILC2s and ILC3s in both untreated (n=2) and ART treated (n=2) individuals over the course of infection, in order to compare these populations at key points during infection, namely: viral detection, peak viremia, and weeks past peak viremia (6-7 weeks post detection). Lacking true biological replicates, HIV- patients in the same study (n=9) were used as replicates to conduct Differential Expression (DE) analysis between time points in both ILC2s and ILC3s on a patient by patient basis. In untreated patients, ILC2s and ILC3s differentially expressed genes associated with apoptosis and cell death between peak viremia and viral detection, while ART treated patients' ILC2s and ILC3s demonstrated a mitigated response. Comparing 6-7 weeks after detection with peak viremia revealed a relative decrease in genes associated in cell death in untreated patients, while ART treated patients showed varied responses where several DE genes were associated with immune response. Overall design: RNA-seq of two Innate Lymphoid Cell populations in 2 HIV+ untreated patients, 2 HIV+ ART treated patients, and 9 HIV- patients (control, replicates).
