AbstractThe need for new immunomodulatory drugs is due to the side effects associated with the prolonged use of the currently used immunomodulatory drugs. In this context, the present work aimed to investigate the immunomodulatory effect of an ethanolic concentrated extract from Physalis angulata. The cytotoxicity of samples was determined using peritoneal macrophages though the Alamar Blue assay. The immunomodulatory activity of the ethanolic extract from P. angulata on activated macrophages was determined by measurement of nitrite and cytokine production. The immunosuppressive effects of the ethanolic extract from P. angulata was evaluated on lymphocyte proliferation and cytokine production. The effects of the extract on cell cycle progression and cell death on lymphocytes were evaluated by flow cytometry. Lastly, the ethanolic extract from P. angulata was tested in vivo in toxicological tests and in models of peritonitis and delayed-type hypersensitivity response. The ethanolic extract from P. angulata decreased nitrite, interleukin-6, interleukin-12, and TNF-α production by activated macrophages without affecting the cell viability. In addition, the ethanolic extract from P. angulata inhibited lymphoproliferation and the secretion of interleukin-2, interleukin-6, and IFN-γ, and increased interleukin-4 secretion by activated splenocytes. Flow cytometry analysis in lymphocyte cultures showed that treatment with the ethanolic extract from P. angulata induces cell cycle arrest in the G1 phase followed by cell death by apoptosis. Moreover, mice treated with the extract from P. angulata at 100 or 200 mg/kg did not show signs of toxicity or alterations in serum components. Finally, the ethanolic extract from P. angulata significantly reduced neutrophil migration and reduced paw edema in bovine serum albumin-induced the delayed-type hypersensitivity response model. Our results demonstrate the potential of the ethanolic extract of P. angulata as an alternative for the treatment of immune-inflammatory diseases.

Chlorophytum borivilianumSantapau & Fernandes (Liliaceae) is a very popular herb in traditional Indian medicine and constitute a group of herbs used as ‘Rasayan’ or adaptogen. Ethanolic extract of the roots and its sapogenin were evaluated for their immunomodulatory activity. Effect of azathioprine-induced myelosuppresion and administration of extracts on hematological and serological parameters was determined. Administration of extracts greatly improved survival againstCandida albicansinfection. An increase in delayed-type hypersensitivity response (DTH), % neutrophil adhesion andin vivophagocytosis by carbon clearance method was observed after treatment with extracts. Immunostimulant activity of ethanolic extract was more pronounced as compared to sapogenins. The results, thus justifies the traditional use ofC. borivilianumas a rasayana drug.

Objective: The present study was intended to evaluate the in vivo immunomodulatory activity of aqueous and ethanolic extract of dried fruits of Capparis moonii Wight. Methods: The effect of both the extracts was evaluated by carbon clearance assay in mice, and they showed a significant increase in the phagocytic index at 50, 100, and 200 mg/kg dose. The effect of the extracts on delayed-type hypersensitivity (DTH) and antibody titer assay was evaluated in ovalbumin immunized mice. Results: Both extracts showed a significant effect on DTH response and stimulation of antibody titer at 200 mg/kg dose. The effects of the extracts in cyclophosphamide-induced myelosuppression mice were also statistically significant. Conclusion: The studies demonstrated specific and non-specific immunostimulating properties of both the ethanol and aqueous extract of C. moonii fruits in various in vivo experimental methods suggesting its therapeutic usefulness in immunocompromised conditions.

Abstract. Yuandani, Nugraha SE, Laila L, Silaban SD, Ramadhani F. 2020. Short Communication: Stimulatory effect of Curcuma mangga on immune response against Staphylococcus aureus. Nusantara Bioscience 12: 109-113. Recently, the ethanol extract of Curcuma mangga Val. rhizomes were found to have immunomodulatory activity by enhancing phagocytic ability. This study was carried out to evaluate the effect of C. mangga rhizomes on antibody titer and delayed-type hypersensitivity response in normal and doxorubicin-induced rats against Staphylococcus aureus. The extract was administered orally at doses of 100, 200, and 400 mg/kg body weight (bw) to rats for 72 hours prior to sensitization of Staphylococcus aureus, then continued for 14 days. Doxorubicin (4.67 mg/kg bw) was administered on days 8 and 11 to suppress the immune system. The antibody titer of normal and immune-suppressed rats after the treatment with C. mangga ethanolic extract was significantly higher than the rats with negative control (P<0.05). Ethanol extract of C. mangga also demonstrated stimulation on delayed-type hypersensitivity response which was indicated by the increase of paw volume. The extract at dose of 400 mg/kg bw showed higher immunostimulatory activity than Levamisole as a positive control. The results indicated that the ethanol extract of C. mangga shows immunostimulatory activity, confirming its potential to be developed as a therapeutic agent.

Delayed Type Hypersensitivity Response

An IFN-gamma-inducible protein, IP-10, has previously been described to belong to a gene family of chemotactic and mitogenic proteins, associated with inflammation and proliferation. Biochemical characterization of this predicted protein has been pursued through the development of polyclonal monospecific antisera to recombinant protein and synthetic peptides. These reagents establish that the IP-10 protein is secreted from a variety of cells (endothelial, monocyte, fibroblast, and keratinocyte) in response to IFN-gamma. Posttranslational processing occurs in the biosynthesis of this protein, resulting in a 6-7-kD species, which may reflect COOH-terminal cleavage. Pulse-chase studies indicate that this processing is a rapid event in the primary cell lines studied, completed in the 30-min labeling period. A model is presented for the processing and secondary structure of this protein. In an accompanying study, Kaplan, et al. using these antisera, demonstrate that the IP-10 protein is associated, in vivo, with a delayed-type hypersensitivity response.

Immunomodulator is a compound that can increaase the imuno system. One of the plants that have immunomodulator’s activity is Waru Leaf (Hibiscus tiliaceus). the purpose of this research was to test the effect of immunomodulator by extract of Waru Leaf ethanol on rat male. The activity of immunomodulator was determined by using digital pletysmometer by measuring the differences between the last leg swelling’s volume and the first leg swelling’s volume. The treatment group were divided into 5 groups. Each group consistof 5 rats CMC-Na 0,5% (negative control), Stimuno®  32,5 mg/kgBW (positive control), dose of EEDW 50, 100 and 200 mg/kgBW, and bacteria E.coli as antigen. The results slowed that distribution of EEDW dose 200 mg/kgBW can give the effect of immunostimulant by swelling enthancement compared by CMC-Na 0,5 %. EEDW 200 mg/kgBW that have activity comparable with Stimuno®  32,5 mg/kgBW. Thus, it is concluded that of Waru Leaf extract has immunomodulator effects on delayed-type hypersensitivity response of rat male.
