Objective: This study aimed to investigate the immunomodulatory capacity of goat kefir on pulmonary fibrosis rat model. Material and Methods: Twenty-five male rats were randomly divided into five groups: one group only received induction with bleomycin (0.3 mg/rat) to induce pulmonary fibrosis; three groups were treated with different doses (2.5, 3.5, and 4.5 mL/200 g BW) of goat kefir, following the induction with bleomycin, for 30 days; and one group served as negative control, did not receive bleomycin induction as well as kefir. On day 30, all the animals were sacrificed. Plasma levels of TGF-β, IL-4, and IFN-y were measured using the ELISA method, and the expression of α-SMA in myofibroblast cells was examined with the help of immunohistochemistry assay. Results: Induction with bleomycin significantly elevated the expressions of TGF-β, IL-4, and IFN-y in comparison to the control group. Following the administration of kefir (3.5 and 4.5 mL/200 g BW), the concentration of TGF-β was significantly decreased (p\<0.05); whereas, the concentration of IFN-y increased slightly (p\<0.05) only in the group that received the 4.5 mL/200 g BW dose of kefir. In contrast, IL-4 exhibited increasing levels with higher doses of kefir (p\<0.05). The expression of α-SMA in myofibroblasts showed a tendency to decline following the administration of kefir, although this decline was not statistically significant. Conclusions: Goat kefir caused a reduction in the TGF-β levels in fibrosis conditions; however, the kefir elicited an immunosuppressive effect during the progression of the pulmonary fibrosis.

Aim: The aim of the present study was to evaluate immune modulatory effect of fractions of D. stramonium L. leaves on human peripheral blood mononuclear cells (PBMC) followed by assessment of cytotoxic abilities of immunomodulated PBMC toward cancer cells. Material and methods: Bioassay (PBMC proliferation) guided fractionation of methanolic leaf extract of D. stramonium was performed to get active fraction and LC-MS was performed to identify the phytocompounds present in the bioactive fraction. The immunomodulatory potential of D. stramonium active fraction was assessed by i) MTT microcytotoxicity assay using A549 (lung carcinomas) and MCF-7 (breast cancer) cell lines and ii) analyzing the production of IL-2 and IFN-\γ by human PBMC in the presence of active fraction. Results: Chromatographic fractionation guided by PBMC proliferation assay of D. stramonium extract resulted in bioactive fraction (fraction-10) exhibiting significant immunostimulatory activity [EC50=19.1\±1.5 (\μg/ml)] on human blood lymphocytes. Fraction-10 pretreated PBMC displayed enhanced cytotoxicity towards A549 and MCF-7 (59\%\±2.1\% and 62\%\±2.3\% at 1:20 effector:target ratio respectively). Moreover, fraction-10 also enhanced the secretion of IL-2 (8 fold) and IFN-\γ (10 fold) by human PBMC. The preliminary phytochemical analysis of fraction-10 from D. stramonium showed the presence of terpenoids and steroids. LC-MS analysis depicted presence of four major phytoconstituents in fraction-10 as daturaolone, daturadiol, stigmasterol and sitosterol with corresponding mass spectrum (m/z) of 440, 442, 412 and 414 respectively. Conclusion: The present report concluded that active fraction-10 of D. stramonium possesses potential immunostimulators that are capable of enhancing anticancer responses of human blood lymphocytes.
