The human fetal placenta promotes tolerance against the semiallogeneic fetus by inducing regulatory T cells and homeostatic M2 macrophages.

J Immunol 2015 Feb 5;194(4):1534-44. Epub 2015 Jan 5.

Clinical Immunology, Department of Clinical and Experimental Medicine, Linköping University, 581 85 Linköping, Sweden; Department of Clinical Immunology and Transfusion Medicine, Linköping University, 581 85 Linköping, Sweden.

A successful pregnancy requires that the maternal immune system is instructed to a state of tolerance to avoid rejection of the semiallogeneic fetal-placental unit. Although increasing evidence supports that decidual (uterine) macrophages and regulatory T cells (Tregs) are key regulators of fetal tolerance, it is not known how these tolerogenic leukocytes are induced. In this article, we show that the human fetal placenta itself, mainly through trophoblast cells, is able to induce homeostatic M2 macrophages and Tregs. Read More

Indoleamine 2,3-dioxygenase-1 (IDO1) in human endometrial stromal cells induces macrophage tolerance through interleukin-33 in the progression of endometriosis.

Int J Clin Exp Pathol 2014 15;7(6):2743-57. Epub 2014 May 15.

Laboratory for Reproductive Immunology, Hospital and Institute of Obstetrics and Gynecology, Shanghai Medical School, Fudan University Shanghai, 200011, China ; Shanghai Key Laboratory of Female Reproductive Endocrine Related Diseases Shanghai, 200011, China.

In the peritoneal fluid, macrophages and their secretory cytokines are essential for endometriosis, but the factors that favor their involvement in the endometriosis-associated inflammatory response are still elusive. Given the anomalous expression of indoleamine 2,3-dioxygenase-1 (IDO1) in endometrial stromal cells (ESCs) and its potentially important roles in immune modulation, we aimed to determine the effects of IDO1 in ESCs on macrophages and the mechanism of those effects. Normal ESCs and ectopic ESCs transfected with the SD11-IDO1 shRNA (short hairpin RNA) or vector-only plasmid SD11 were subsequently co-cultured with peripheral blood (PB)-derived monocytes (PBMC)-driven macrophages directly and indirectly.

Interleukin-1β triggers the differentiation of macrophages with enhanced capacity to present mycobacterial antigen to T cells.

Immunology 2014 Feb;141(2):174-80

Division of Dermatology, Department of Medicine, David Geffen School of Medicine, University of California, Los Angeles, CA, USA.

The rapid differentiation of monocytes into macrophages (MΦ) and dendritic cells is a pivotal aspect of the innate immune response. Differentiation is triggered following recognition of microbial ligands that activate pattern recognition receptors or directly by pro-inflammatory cytokines. We demonstrate that interleukin-1β (IL-1β) induces the rapid differentiation of monocytes into CD209(+) MΦ, similar to activation via Toll-like receptor 2/1, but with distinct phenotypic and functional characteristics.
