Over the same period, compared to placebo, analysis of bacterial flora on the scalp shows a statistical trend in total Malassezia count and in species more specifically associated with dandruff conditions such as Malassezia globosa and Malassezia restricta.

All together, these results suggest that ST11-mediated protection against colitis seems to be mediated by in vivo immunomodulatory properties of ST11 rather than gut barrier function modulation. To get more insights into how ST11 mediates its protective effect against colitis, further analyses were made on colonic samples. Transferred cells also express gut-homing classical markers CD103 and β7 integrin (Figures 4(b) and 4(c)). Sensitive skin is common in conditions such as atopic dermatitis, contact dermatitis, psoriasis, rosacea, and urticaria. To this purpose, Lactobacillus paracasei NCC 2461 (ST11) was selected because of its specific beneficial skin properties discovered in in vitro studies, i.e. All Activity; Home; Facebook; Twitter; Instagram; Youtube; DEVGRU / SEAL Team Eleven.


These results correlated with a significant improvement in facial skin roughness (. • Subject with moderate to severe dandruff with scoring equal to or above 3 (scale of 0-4) for dandruff over at least two quadrants of the head. Hence, we and others never observed adverse events in ST11-fed mice or human. or any other healthcare professional. inclusion criteria • Male healthy subject aged 18-60 years.

Barrier dysfunction leads to increased penetration of irritating substances and transepidermal water loss (TEWL). This reduction in favour of ST11 appeared to be a trend at day 29 (p=0.0883). …

Rag2-/- recipient mice were fed with ST11 (109 CFU/day)a month prior toinduce colitis by adoptive transfer of naive T cells. All animal displaying signs of pain or >10% weight loss have to be prematurely killed. ST11-, LPS-, and LTA-activated BM-DC produced at least similar levels of IL-1β and IL-6, whereas IL23 was hardly detectable in all conditions in our hands. Sensitive skin is also characterized by impaired recovery of skin barrier function. • Sachet of powder. In order to test whether ST11-fed mice harbor better gut barrier condition, expression of mRNA for specific antibacterial peptides and tight junction proteins were quantified.

The studies made so far underline the need to further study and understand IBD in order to optimize the potential nutritional solution to ameliorate IBD.

The World Health Organization defines probiotics as living microorganisms which, when consumed in adequate amounts, confer a health effect on the host.

Proteins from colon samples were prepared in RIPA buffer (Sigma) and protein measured with bicinchoninic acid assay kit (Thermo scientific). ST11 enhanced restoring the scalp microbiota after 56 days of supplementation when compared to the placebo. This study builds on prior investigations led by two of the authors (Gueniche and Philippe) at their respective positions in the research laboratories of L’Oreal in France and Nestle in Switzerland.

Self-assessments paralleled these findings.

C57BL/6 bone marrow-derived dendritic cells (BM-DCs) were differentiated in vitro using previously described protocol [23]. Gene-expression levels for cytokines, antimicrobial peptides and tight junction proteins were determined by real time quantitative PCR for each sample and normalized to the level of house-keeping GAPDH gene expression. Surprisingly, in clear contrast to LPS or LTA, ST11-activated BM-DCs were low Th1 inducers in TGFβ-free cocultures (Figure 2(b)) and very poor Th17 inducers in TGFβ-containing cocultures (Figure 2(c)) compared to LPS or LTA. All antibodies were purchased from eBiosciences.

We also observed that daily intake of ST11 tends to interfere with Helicobacter pylori colonization in healthy infants and adults [21, 22]. We conclude that the optimised chromatographic method is quick, robust and sensitive for quantifying nucleotides and NSs. The same effects are perceived by subjects during self-assessment. We conclude that probiotics such as Lactobacillus paracasei harbor worthwhile in vivo immunomodulatory properties to prevent intestinal inflammation by nutritional approaches. We showed that ST11 can strongly decrease colitis development in a preventive protocol. 1) and up until the end of the study. diminution of neurogenic inflammation and promotion of the recovery of skin barrier function. However, as ST11 feeding did not influence those gut barrier gene expression, we ruled out this hypothesis. results 1.1 clinical assessment Dandruff, Erythema: At each visit, dandruff status (free and adherent dandruff) and erythema were scored by the investigator on a scale from 0-4 on each quadrant of the head The total head quadrant scores for free, adherent dandruff and erythema were calculated (scores could therefore be between 0-16). M. Oliveira and N. Bosco contributed equally to this work.

results 1.1 clinical assessment Dandruff, Erythema: At each visit, dandruff status (free and adherent dandruff) and erythema were scored by the investigator on a scale from 0-4 on each quadrant of the head The total head quadrant scores for free, adherent dandruff and erythema were calculated (scores could therefore be between 0-16). Their results reinforce the concept of an inside-out, outside-in approach to the treatment of common skin disorders such as atopic dermatitis, psoriasis, and acne. All together, our results demonstrate that oral administration of ST11 was safe and had a significant preventive effect on colitis. -tests for unpaired data when said or nonparametric Wilcoxon tests with the software SAS 9.1 when appropriate. In our protocol, ST11 efficiently colonize GIT (data not shown) as previously described in mouse and human [18, 20] and displayed interesting in vitro immunomodulatory properties (above results), therefore we tested whether ST11 could be a potent anti-inflammatory strain in vivo allowing protection against intestinal damages associated with IBD. Farage MA, Katsarou A, Maibach HI. 3 Gueniche had demonstrated that a medium conditioned with ST11 significantly reduced substance P–induced vasodilation, edema, mast-cell degranulation, and tumor necrosis factor release, and also promoted recovery and maintenance of skin barrier function… In order to provide comprehensive care to patients with sensitive skin, probiotic strains should be selected with proven benefit for these conditions and ideally prescribed at proven-effective dosages. At the end of the study, we observed a 70% reduction in the free dandruff score for subjects treated with ST11 and a 23% reduction for subjects treated with placebo. Herein, we show that ST11 probiotic strain harbors immune modulating properties in vitro and in vivo which reduce colitis. Thus, by introducing TGFβ into coculture, we restore in vitro Th17 differentiation (about 60%) and reduce Th1 differentiation (<2%) (Figure 2(a), right panel). Female mice were used around 7 weeks of age and ST11-fed for the next 8 weeks (4 weeks pre- and postcolitis induction) as described below. By Betsy Bartlett, nutraMetrix Research Coordinator. These results are in line with those of the self-assessments of dandruff and with clinical score assessments combining dandruff and erythema score.

We did not observe a significant reduction in effector T cells in ST11-fed compared to PBS-fed colitic mice, despite a weak Th1/Th17 generation potential in vitro. His father was a dermatologist, and this inspired Traub to undertake extra study in this subject and become the leading expert in dermatology in the naturopathic profession.

It is appealing to design probiotic-based preventive diet in order to maintain GIT homeostasis or prevent development of chronic inflammation. Dandruff is a common persistent, relapsing inflammatory condition affecting the scalp. The cDNA was stored at −20°C until use. There is a growing body of … Panduru M, Panduru NM, Salvastru CM, Tiplica GS. Thus, we believe that ST11 exerts a pivotal immunomodulatory role on innate cells which initially dampens global inflammatory responses per se thereby limiting subsequently intestinal tissue damages. After colitis induction, ST11 feeding continues during 4 weeks posttransfer. As LPS and LTA, ST11 induced clear CD40, CD80, CD86 costimulatory molecules upregulation (Figure 1(a)). primary outcome Clinical assessment of dandruff on the scalp (free and adherent dandruff) secondary outcomes-Clinical assessment of erythema and seborrhoea on the scalp-Self-assessment of dandruff, pruritus, greasiness, irritations, redness, stretching sensation and overall perception of the scalp-Typing of Malassezia yeasts.-Assessment of overall clinical efficacy at the end of treatment-Assessment of residual effect after 7 days on all criteria materials and methOds A comparative, controlled, randomised, double-blind and parallel group study of 30 subjects: one group using the trial product and one group using the placebo.

Guidelines for transepidermal water loss (TEWL) measurement. 1International Journal of Women’s Dermatology; Volume 1, Issue 2, June 2015, Pages 85-89, 2 Immune modulation property of Lactobacillus paracasei NCC2461 (ST11) strain and impact on skin defenses Beneficial Microbes: 5 (2) – Pages: 129 – 136.
Results were compared to immature BM-DCs cultured in medium alone or exposed to LPS (0.1 μg/mL) or LTA (1 μg/mL) as positive control. Mounting instructions … challenge is to interrelate different levels of information, from the genome to the transcriptome, the proteome and the metabolome, and experimental data from widely used high-throughput techniques to recreate a given phenotype and ultimately to make predictions about network and cellular behaviour. We detected a significant reduction of colonic MPO level in ST11-fed compared to PBS-fed colitic mice (119.9 ± 9.8 versus 212.6 ± 37.3 ng/mg of total proteins); whereas in healthy mice, MPO levels measured were very low (29.9 ± 3.3 ng/mg of total proteins) (Figure 3(b)). ST11 is a go-to probiotic for regulation of a person’s intestinal immune system – over 70% of your immune system by cell count is found in your gut. It 1) and up until the end of the study. However, little is known about its capacity to alleviate inflammatory symptoms in vivo In this context, the main objective of this study was to investigate the role of ST11 on intestinal inflammation using the adoptive transfer mouse model of experimental colitis. In rodents, different probiotic cocktails (some are already commercially available) were effective in preventing or reducing gut inflammation when administrated before inducing intestinal injury.
