  • Lipid receptor fosters infection of the uterus in bitches

    Foamy epithelial cells of the uterus aggregate lipids via a receptor and support pregnancy in bitches. The receptor equally attracts bacteria, which may cause an infection (green: foamy cells). Cordula Gabriel/Vetmeduni Vienna

    In the female dog, cells of the uterus can accumulate lipid droplets to form so-called foamy epithelial cells during late metoestrus. These cells produce a hormone that is involved in the implantation of the embryo in the uterus. A team of researchers from the Institute of Anatomy, Histology and Embryology at Vetmeduni Vienna has now shown for the first time that the factor assisting the cells in lipid accumulation also facilitates the binding of bacteria to the epithelial cells, resulting in serious infections of the uterus in female dogs. Two studies on this subject were published in the journals Anatomia, Histologia, Embryologia and Theriogenology.
