Bovine PBMCs (105 cells/well) were depleted of (A) monocytes or (B) cd T cells and treated with 20 mg/ml oenothein B or X-VIVO medium alone for 24 hrs. Cells were then washed and treated with 10 ng/ ml rhu IL-18 or medium alone for 18 hrs. After incubation, IFNc levels in the 79983-71-4 biological activity supernatant fluids were measured by ELISA. The data are expressed as mean +/2 SEM of three independent experiments comparing depleted PBMCs to un-depleted controls MedChemExpress SPDB tested concurrently. All samples were tested in duplicate or triplicate. Statistical significance was measured by Two-way ANOVA with Bonferroni post-test. *p,0.05, **p,0.01, ***p,0.001 (TIF)AcknowledgmentsWe would like to thank Dr. Robyn Klein (Department of Plant Sciences and Plant Pathology, Montana State University, Bozeman, MT) for plant identification.

Iron deficiency (ID) is the most common and widespread nutrient deficiency, affecting approximately two billion people worldwide and resulting in over 500 million cases of anaemia [1,2]. In 23727046 sub-Saharan Africa, the prevalence of iron-deficiency anaemia (IDA) is estimated around 60 [1,2], with 40 to 50 of children under five years of age in developing countries being iron deficient [3]. ID has been estimated to cause around 800,000 deaths and 35,057,000 disability adjusted life years lost annually [2], with the greatest toll in South-East Asia and Africa [1,4]. By six months of age there is a physiological depletion of the iron stores that were accumulated by the foetus in the last months of pregnancy. If the infant’s diet does not provide enough iron, there is a significant risk to develop IDA. This physiological iron deficiency is often exacerbated by the early introduction of weaning foods [4], that frequently contain iron absorption inhibitors [5]. Iron deficiency may also be worsened by intestinalchronic blood loss from intestinal parasitic infections [3,6]. All these determinants are frequent in developing countries, leading to a prevalence of ID that may reach more than 30 by 12 months of age [7]. Because IDA tends to develop slowly, adaptation occurs and the disease can go unrecognized for long periods, yet having an i.Romising candidate for therapeutic development to supplement immunotherapies, especially those involving IL-18.measured by multi-color flow cytometry.
