This study was performed to evaluate the immunoregulatory effects of Gungchihwadam-Jeon(궁치화담전, GCHDJ) and Cheongsinhwadam-Jeon(청신화담전, CSHDJ) was administered(p.o.) once a day for 14 days to mice. By the treatment of GCHDJ or CSHDJ was increased the cell viability of cultured mice splenocytes, thymocytes and mesenteric lymph node cells. Administration of GCHDJ or CSHDJ was increased the splenic T lymphocyte, especially the Tc cell subpopulation was increased by the GCHDJ, on the while the TH cell was increased by the CSHDJ. The administration of GCHDJ or CSHDJ was significantly increased the apoptosis of transplanted-L1210 leukemia cells to mice peritoneal cavity. These results suggest that GCHDJ and CSHDJ have an immunoregulatory action

The purpose of this research was to investigate the immunoregulatory effect, apoptosis of L 1210 leukemia cells of Comus officinalis Sieb.et Zucc. The proliferation of cultured splenocytes and thymocytes were enhanced by the addition of SSY. Splenic, thymic and mesenteric lymph node-T lymphocytes, especially TH cells was significantly increased in SSY-administered (p.o. for 7 days) mice. SSY treatment induced the apoptosis of L1210 mouse leukemia cells. In addition, SSY accelerated the phagocytic activity and nitric oxide production in peritoneal macrophages. These results suggest that SSY have an immuno-regulatory property and anti-cancer effect.

There are several data in the literature indicating a great variety of pharmacological activities of Polypodium genus, which exhibit antiinflammatory and immunomodulatory activities. Since one of our main interests is to obtain natural immunoregulatory agents devoid of pharmacological adverse effects, we used flow cytometry analysis to highlight relative contributions of a water-soluble fraction of different concentrations of Polypodium rhizome extracts on lymphocyte subpopulations, NK and LAK activity. To measure their potential immunoregulatory activity a T cell proliferation assay in response to phytohemaglutinin (PHA) and mixed lymphocyte reactions were chosen. As a confirmatory bioassay we studied the effect of our extracts on CD45RO and CD95 antigen expressions. The results indicate that CD95 expression dramatically increases after peripheral blood lymphocyte activation and treatment with Polypodium leucotomus, cambricum and vulgare extracts, suggesting a powerful intrinsic pro-apoptotic effect.

Various beneficial effects have been described for fermented papaya preparation (FPP: SAIDO-PS501) based on its anti-oxidative and anti-inflammatory functions. The present study was designed to determine the effects of FPP on carcinogenesis in vivo, and immunomodulatory function in vitro. Mice were injected with RL male 1 cells subcutaneously or 3-methylcholantherene (MCA) intravenously to induce cancer and orally or intraperitoneally treated with FPP solution. Human peripheral blood mononuclear cells (PBMC) were obtained from healthy volunteers and patients with atopic dermatitis, treated with FPP, and subjected to measurement of cytokine production and changes in Foxp3-expressing regulatory T cell (Treg) stimulated with phytohemagglutinin (PHA). Administration of FPP suppressed tumor size and the incidence of malignancy. In vitro, treatment of PBMC with FPP induced IL-$1{\beta}$, $TNF{\alpha}$ and $IFN{\gamma}$ production. Moreover, FPP suppressed proliferation of PHA-stimulated Foxp3-expressing Treg. These results suggest that FPP has chemotherapeutic properties.

Polysaccharides fractions from the leaves of Artemisia selengensis$(ASP_1)$ and Artemisia iwayomogi$(ASP_1)$ were extracted and purified by Sephadex gel filtration and DEAE-Sephadex ion exchange chromatographies. Both $ASP_1$ and $AIP_1$ fractions were tested for their effects on the spleen cell culture in vitro. Both $ASP_1$ and $AIP_1$ fractions allow growth of spleen cells up to 3 months in culture, suggesting the immunoregulatory activities of those polysaccharide fractions. The molecular weights of $ASP_1$ and $ASI_1$ fractions were found to be about 2,500 daltons by Sephadex gel filtration chromatography using standard dextrans. Both $ASP_1$ and $AIP_1$ fractions were composed of glucose, xylose and galactose.

Current immunosuppressants have nonspecific immuosuppressive effects, and are not helpful for tolerance induction. Consequently, transplant patients cannot discontinue using them, and their nonspecific immunosuppressive effects result in many side effects, including infection and malignancy. However, most of cellular immunotherapy can have donor antigen-specific immunsuppressive effects. Therefore, cell therapy could be an alternative or adjunctive to nonspecific immunosuppressants. Polyclonal or antigen-specific Foxp3+ regulatory T cells have been actively tried for prevention of acute rejection, treatment of chronic rejection, or tolerance induction in clinical trials. Regulatory macrophages are also under clinical trials for kidney transplant patients. IL-10-secreting type 1 regulatory T cells and donor- or recipient-derived tolerogenic dendritic cells will also be used for immunoregulation in clinical trials of kidney transplantation. These cells have antigen-specific immunoregulatory effects. Mesenchymal stromal cells (MSCs) have good proliferative capacity and immunosuppressive actions independently of major histocompatibility complex; therefore, even third-party MSCs can be stored and used for many patients. Cell therapy using various immunoregulatory cells is now promising for not only reducing side effects of nonspecific immunosuppressants but also induction of immune tolerance, and is expected to contribute to better outcomes in transplant patients.
