The study of sperm cellular components at molecular level is crucial for the diagnosis of male unexplained infertility. The aim of the study was to compare the molecular profile of steroid receptors and aromatase in spermatozoa obtained from two normozoospermic groups of patients issued from couples treated for infertility. We investigated 46 male patients from unexplained infertility couples and from men, 38 where female partners presented with tubal infertility. Sperm ERs (estrogen receptors: alpha and beta), GPER (G protein-coupled estrogen receptor), AR (androgen receptor) and aromatase mRNA expression levels by TaqMan qPCR were analyzed. AR transcript level was significantly lower in sperm of men from unexplained infertility couples vs. men from couples with tubal factor infertility (P = 0.04). Although the AR mRNA expression level did not had any effect on embryo development and its implantation, a significant correlation between AR mRNA levels and clinical pregnancy in unexplained infertility patients was observed. Taken together, AR transcript presence in ejaculated spermatozoa could be a potential marker for unexplained infertility.

Noncanonical intercellular communication in immune response

引用

World Journal of Immunology 2016年第1期6卷 67-74页

作者： Malgorzata Kloc jacek z.kubiak Xian C Li Rafik M Ghobrial Department of Surgery Methodist Hospital Houston Methodist Research Institute Centre National de la Recherche Scientifique Unités Mixtes de Recherche 6290 Institute of Genetics and Development of RennesCell Cycle GroupFaculty of Medic-ineUniversity of Rennes Faculty of Medicine University of Rennes 1 Sherrie and Alan Conover Center for Liver Disease and Transplantation

The classical view of signaling between cells of immune system includes two major routes of intercellular communication:Through the release of extracellular molecules or a direct interaction between membrane bound receptor and its membrane bound ligand,which initiate a cascade of signaling in target ***,recent studies indicate that besides these canonical modes of signaling there are also noncanonical routs of intercellular communications through membrane stripping/membrane exchange/trogocytosis,extracellular traps,exosomes and ectososmes/*** this review we discuss what are the components of noncanonical pathways of signaling and what role they play in immune cells interactions.
