The invention discloses an efficient CIK amplifying method, in particular to a method for cell populations, namely cytokine-induced killer cells utilizing in-vitro cell factors for efficiently inducing mononuclear cell expressions CD3 and CD56 of peripheral blood, wherein the cell populations have killing functions. The cultivation method for the CIK efficiently expressing CD3+CD56 comprises the following steps that the peripheral blood of a healthy person or a patient is collected in a sterile mode, after the peripheral blood is diluted through a saline solution with the same volume, a Ficoll lymphocyte separating medium is used for separating mononuclear cells, in the CIK cell inducing process, CD3 monoclonal antibodies (CD3mAb), CD28 monoclonal antibodies (CD28mAb), interferon-gamma (IFN-gamma), interleukin-2(IL-2) and interleukin 1alpha (IL-1alpha) are added, cultivation is carried out for 13-16 days to obtain cells, a CIK cell preparation is prepared, and flow cytometry detection and microorganism detection are carried out. According to the CIK cultivation method, the CIK number can be increased to be 6*10<9> or over 6*10<9> in two weeks, the cell survival rate can be increased to be 99% or over 99%, and the double-positive proportion of the CD3+CD56+cells reaches 30% or over 30%.

A mechanism of macrophage-induced T cell suppression is the selective elimination of tryptophan and/or increase in one or more tryptophan metabolites within the local macrophage microenvironment Studies demonstrate that expression of IDO can serve as a marker of suppression of T cell activation, and may play a significant role in allogeneic pregnancy and therefore other types of transplantation, and that inhibitors of IDO can be used to activate T cells and therefore enhance T cell activation when the T cells are suppressed by pregnancy, malignancy or a virus such as HIV. Inhibiting tryptophan degradation (and thereby increasing tryptophan concentration while decreasing tryptophan metabolite concentration), or supplementing tryptophan concentration, can therefore be used in addition to, or in place of, inhibitors of IDO. Similarly, increasing tryptophan degradation (thereby , decreasing tryptophan concentration and increasing tryptophan metabolite concentration), for example, by increasing IDO concentration or IDO activity, can suppress T cells. Although described particularly with reference to IDO regulation, one can instead manipulate local tryptophan concentrations, and/or modulate the activity of the high affinity tryptophan transporter, and/or administer other tryptophan degrading enzymes. Regulation can be further manipulated using cytokines such as macrophage colony stimulating factor, interferon gamma, alone or in combination with antigen or other cytokines.

The invention provides a pig IFN (interferon) gamma-Fc fusion protein optimized according to a silkworm reaction system and a coding gene of the pig IFNgamma-Fc fusion protein and a method of expressing pig IFNgamma-Fc fusion protein by using a silkworm bioreactor, and belongs to the field of a biological genetic engineering. The pig interferon gamma serving as a non-special broad spectrum antiviral biological agent has a wide medicinal prospect in a veterinary drug field; but like most of genetic engineering veterinary drugs, the pig interferon gamma also has the problems such as insufficient output, expensive price, irregular quality, short acting time and the like. A target protein with a high expression efficiency and strong activity is obtained by expressing the pig IFNgamma-Fc fusion protein optimized by using a silkworm expression system. In addition, the acting time of the pig interferon gamma is prolonged by addition of an Fc segment, so that the overall immune regulation effect is enhanced, and purification at a later stage is facilitated, thus a pig IFNgamma-Fc fusion protein preparation produced by using a genetic engineering method is possible, and a condition is also created for developing a novel feed containing the fusion protein.

The invention discloses an identification and preparation method and application CD106-positive mesenchymal stem cells. The method comprises the following steps: identifying and isolating CD106-positive cells from mononuclear cells isolated from bone marrow, placenta or other tissues through an immunological method, carrying out adherent culture, and collecting adherent CD106-positive cells; or carrying out adherent culture of mononuclear cells isolated from bone marrow, placenta or other tissues, collecting adherent mesenchymal cells, and isolating the CD106-positive mesenchymal stem cells when the count of the obtained cells is large enough. The CD106-positive cells are mesenchymal stem cells with adherent growth, express mesenchymal stem cell-related immunological phenotype, and have osteogenesis, adipogenesis and other differentiation potencies. Compared with CD106-negative mesenchymal stem cells, the CD106-positive cells have higher immunosuppression capacity, can better inhibit proliferation of IFN-gamma (interferon-gamma) secretion of lymphocytes, and can be used for treating graft versus host disease (GVHD) and autoimmune diseases.
