Abstract: The subject matter of the present invention relates to a ligand of Axl receptor tyrosine kinase used to induce the differentiation from precursor natural killer cell to mature natural killer cell. In addition, it relates to a process for producing mature natural killer cell comprising treating hematopoietic stem cells with interleukin-7, stem cell factor and Flt3L to differentiate into precursor natural killer cells, and treating the resulting precursor natural killer cells with at least one ligand of Axl receptor tyrosine kinase to produce mature natural killer cells.

Abstract: Live strains of Lactobacillus acidophilus HY2177 and Lactobacillus casei HY2743 maintained in nutritious foods, such as yogurt, imbue them with prophylactic and/or therapeutic properties. Such foods are beneficial in the prevention and/or treatment of gastritis, duodenal and gastric ulcers caused by infection from Helicobacter pylori (also referred to as H. pylori). The properties of these bacteria are boosted by the addition of egg yolk containing antibodies specific to H. pylori antigen derived from “fractionated H. pylori” and may be administered as active strains alone in a food supplement, or the active strains may be combined with H. pylori-antibodies (IgY).
