This could be due to the fact that all gram-positive leucnostoc are likely to use the same or similar intracellular signal transduction mechanisms to induce cytokine gene expression.
Lactobacilli from human gastrointestinal mucosa are strong stimulators of IL production. In this study we have systematically analysed the ability of potentially probiotic bacterial strains from six different genera; StreptococcusLactobacillusBifidobacteriumLactococcusLeuconotoc and Propionibacteriumto induce cytokine expression in vitro in human PBMC.
Journal List World J Gastroenterol v. Bergey’s Manual of Determinative Bacteriology9th ed. Activation of human peripheral blood mononuclear cells by nonpathogenic bacteria in vitro: Holm SE, Falsen E. Therefore, in vitro bacteria-host cell studies aid in selecting novel probiotic strains for clinical trials.
Cytokine specific ELISA Cell culture supernatants obtained from individual donors were analyzed for cytokine levels by using enzyme-linked immunosorbent assay ELISA essentially as previously described[ 8 ]. Some end products of note are mannitol, acetate, and lactate, but other pathways exist.
Probiotics and prebiotic galacto-oligosaccharides in the prevention of allergic diseases: On the contrary, E. IL was induced by Bifidobacterium and Propionibacterium strains, whereas IL production induced by StreptococcusLactobacillusLactococcus and Leuconostoc strains remained at a low level. Ceemoris RNA analysis cells from different donors were pooled. Probiotics reduce the prevalence of oral candida in the elderly–a randomized controlled trial. J Nutr Health Aging.

In the present study we have analysed the cytokine production of eleven different potentially probiotic strains from six bacterial genera alone or in combinations in human peripheral blood mononuclear cells in order to indentify potential enhancing or synergistic effects. Bacteria-induced stress produces inflammatory cytokines promoting the activation of antimicrobial immune responses. The anti-inflammatory actions of IL could be helpful in the treatment of inflammatory conditions or diseases.
Differential cytokine response from dendritic cells to commensal and pathogenic bacteria in different lymphoid compartments in humans.
Identification of strong interleukin inducing lactic acid bacteria which down-regulate T helper type 2 cytokines. To control equal loading, ethidium bromide staining was used. Next the kinetics of cytokine production in PBMC using a Ethidium bromide staining of gels was used to verify equal loading of RNA. They are a facultative anaerobe and are a member of the lactic acid bacteria family, which includes Oenococcus oeniwhich are also closely related to the Lactobacillaceae also a LABwhich split off from the Streptococcaceae Marakova et al.

Interestingly, no additive or synergistic induction of cytokine production was seen even when gram-positive probiotic bacterial strains were combined with a gram-negative bacteria, E. Bergey’s Manual of Systemic BacteriologyVol.
All strains of Lactobacillus were weak inducers of IL and Th1 type cytokines. Stedman’s Medical Dictionary25th ed. Understanding of the immunological properties of probiotic bacteria is needed in the development of probiotic bacteria for targeted treatment of different disease conditions. Bacterial doses and incubation times are as indicated for each experiment.
This results in the break down of glucose and other sugars into D-lactate, ethanol, and CO2 Demoss et al ; Garvie ; Gottschalk The bacteria is also a nonsporogenous and non-motile species.
