The described invention provides a pharmaceutical composition comprising a therapeutic amount of an educated mononuclear cell product, a process for preparing the educated mononuclear cell product, and a method for treating a disease characterized by lymphocyte autoreactivity. Mononuclear cells from a diseased subject are co-cultured with a viable population of adherent umbilical cord blood stem cells at at least 80% confluence to form an educated mononuclear cell product. A therapeutic amount of the educated mononuclear cell product is returned by infusion intravascularly to the subject. The therapeutic amount is effective to modulate autoreactivity in a T cell compartment of the subject and to reduce symptoms of the disease characterized by lymphocyte autoreactivity.

The present application relates to probiotic compositions, e.g., comprising at least one bacterial strain selected from: Streptococcus thermophilus, Bifidobacterium longum, Bifidobacterium breve, Bifidobacterium infantis, Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus paracasei, KE99, and Lactobacillus bulgaricus, optionally wherein the at least one bacterial strain is either alive or sonicated.

Provided is a method for preparing and using cell ghosts with active factors as a synergist of a lymphocyte in vitro culture. The method for preparing cell ghosts comprises: washing a cell to obtain a washed cell; and cleaving the washed cell to obtain cell ghosts, wherein the cell has cytokines capable of promoting the proliferation and differentiation of lymphocytes on their surface.

The present invention provides a formulation and method for preparing specific T cells, and a method for fabricating the formulation is also disclosed. The formulation can induce specific T cell responses, and comprises at least a cell population of dendritic killer cells presenting specific antigens. In addition, the method mentioned above for preparing specific T cells comprises following steps. A T cell population is provided, and then a formulation of preparing specific T cells is mixing with the T cell population. After cultivating, the specific T cells are harvested. Furthermore, the method for fabricating the above formulation comprises the following steps. First, a cell population of dendritic killer cells is provided. A target sample is then provided, and a step of making the cell population of the dendritic killer cells is co-cultivated with the target sample. After co-cultivating, a cell population of dendritic killer cells presenting specific antigens is harvested.
