- Estrogen receptor alpha (ER alpha) is an important regulator of the estrous cycle and mice with global ER alpha deletion, as well as some conditional knockout mouse lines, have an interruption in the estrous cycle. In this study we observed that conditional ERa knockout mice where the Cre gene is regulated by the rat insulin promoter (RIP), RIP-Cre/ER alpha(KO) mice, have a 3.7-fold increase in serum 17 beta-estradiol levels, blocked estrous cycle, and develop a fluid-filled uterus (hydrometra). Using a proteomics approach, we identified three proteins, lactoferrin, complement C3 and chitinase 3-like protein 1 (CHI3L1), as highly expressed proteins in hydrometra fluid. The mRNA levels of the corresponding genes were more than 50-fold higher in RIP-Cre/ER alpha(KO) uterus compared to controls. High expression of CHI3L1 in the uterine fluid was not reflected as elevated levels in the serum. The high expression of lactoferrin, complement C3 and CHI3L1 in the uterine fluid, in association with elevated estrogen levels, prompted us to address if the expression of these genes is related to reproduction. However, gonadotropin treatment of mice reduced the uterine expression of these genes in a model of in vitro fertilization. Our findings identify lactoferrin, complement C3 and CHI3L1 as highly expressed proteins in hydrometra fluid in association with chronically elevated serum estradiol levels. (C) 2015 Elsevier Inc.

- IL-10 is a prototypical anti-inflammatory cytokine, which is fundamental to the maintenance of immune homeostasis, especially in the intestine. There is an assumption that cells producing IL-10 have an immunoregulatory function. However, here we report that IL-10-producing CD4+ T cells are phenotypically and functionally heterogeneous. By combining single cell transcriptome and functional analyses, we identified a subpopulation of IL-10-producing Foxp3neg CD4+ T cells that displays regulatory activity unlike other IL-10-producing CD4+ T cells, which are unexpectedly pro-inflammatory. The combinatorial expression of co-inhibitory receptors is sufficient to discriminate IL-10-producing CD4+ T cells with regulatory function from others and to identify them across different tissues and disease models in mice and humans. These regulatory IL-10-producing Foxp3neg CD4+ T cells have a unique transcriptional program, which goes beyond the regulation of IL-10 expression. Finally, we found that patients with Inflammatory Bowel Disease demonstrate a deficiency in this specific regulatory T-cell subpopulation.
