IroB is a C-glycosyltransferase encoded in the iroA cluster. C-Glucosylation of the bacterial siderophore enterobactin by IroB is a strategy some pathogenic bacteria use to evade the host's innate immunity mediated by lipocalin 2 (Lcn2). Without this modification, enterobactin can be tightly bound by host Lcn2, rendering it ineffective as a siderophore. Therefore, IroB inhibitors could be poten...

A growing body of evidence indicates that the kidneys contribute substantially to immune defense against pathogens in the urinary tract. In this issue, Paragas et al. report that α-intercalated cells (A-ICs) within the nephron collecting duct sense infecting Gram-negative bacteria, resulting in simultaneously secretion of the iron chelating protein lipocalin 2 (LCN2) and protons, which acidify ...

Endometriosis is an estrogen-dependent gynecologic disease, which characterized by the elevated ratio of ERβ/ERα expression. Retrograde menstruation leads to ectopic erythrocytes deposition and iron overload at pelvic cavity in endometriosis. Lipocalin 2 (LCN2) a secretory protein that plays important role during transport metabolism. To date, relationship estrogen homeostasis not well studied ...

PURPOSE Autoimmune uveitis is a sight-threatening disease in which autoreactive T cells cross the blood-retinal barrier. Molecular mechanisms contributing to the loss of eye immune privilege in this autoimmune disease are not well understood. In this study, the authors investigated the changes in the matrix metalloproteinase network in spontaneous uveitis. METHODS Matrix metalloproteinase (MM...

Obesity is a worldwide public health concern, and prevalence in the United States continuously increasing. Treatment of obesity ranges from dietary approaches to gastric surgery; there no one-size-fits-all approach. In recent years, ketogenic diet (KD) has become popular approach for weight loss metabolic promotion. The main mechanism caused by this promote body use fat as its primary form ener...
