This appears to build a consensus in the pharmaceutical and food communities about the role of probiotics in the prevention and treatments of common allergies. Food allergy is one of the common allergies, defined as an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a given food. Improving the digestion of foods and maintaining a healthy gastrointestinal (GI) tract is certainly critical to controlling food allergens. Therefore, the association between a leaky gut or an impaired intestinal permeability and food-allergenic reactions is explained. Gluten has been found to be somehow a justification for protein allergy, and should, therefore, be avoided by people with celiac disease. In several, in vitro models, surface layer (S- layer) proteins of selective paraprobiotics have shown potential in alleviating food allergies and intestinal disorders. Notably, lactobacilli paraprobiotics have proven to be the immediate immunomodulators against common allergies and other diseases, including viral (flu, hepatitis C), bacterial (bronchitis), asthma, chronic fatigue, fibromyalgia, gastrointestinal distress, and autism disorders in humans.展开更多

Oral ingestion of GK-1 was previously reported to help maintain immunity and reduce nasal discomfort. Considering the suggested mechanism of action of activation of regulatory T cells via TLR4 to control Th1/Th2 balancing, GK-1 is also assumed to reduce skin discomfort secondary to immune reactions;however, this has not been validated in humans. Thus, we conducted a randomized, double-blind, placebo-controlled, parallel-group study on 100 healthy Japanese men and women (mean age, 47.6 ± 1.01 years) aged 20–64 years who consumed GK-1 (9 × 109 cells) daily for 8 weeks. Visual analog scale for overall, facial, arm, and leg skin discomfort was assessed before and after ingestion. The cumulative days of skin discomfort during the ingestion period were assessed. Compared with the placebo group, the G. hansenii GK-1 group had a significantly lower visual analog scale for overall and facial skin discomfort after 8 weeks and cumulative days of skin discomfort. Moreover, there were no adverse events attributable to G. hansenii GK-1. This study confirmed that oral ingestion of G. hansenii GK-1 contributed to skin integrity. The study protocol was preregistered at the Clinical Trials Registry System (registration no. UMIN000053005, December 7, 2023).展开更多

With cell fragment technology (CFT?), the structural fragments are isolated and purified from live probiotic cells. While observed to be strain-dependent as in the case of live probiotics, orally administered PCFs demonstrated a broad spectrum of immune modulation functions;anti-allergy;anti-inflammation;anti-bacterial and anti-viral properties;anti-mutagenic;and radioprotective and detoxification abilities in humans and animals. The PCFs mechanisms of action include events of motifs of cell wall peptidoglycans, DNA motifs, nucleotide containing components, lipoteichoic acids (LPAs), surface layer (S-layer) proteins, and cytoplasmic proteins. Different immunological in vivo-in vitro tests have shown that PCFs, essentially, have the ability to stimulate the macrophages, and induce cytokines such as interleukins, tumor necrosis factors (TNFs), interferons (IFNs), and natural killer (NK) cells. PCFs may be used as ingredients for foods and beverages or as nutritional supplements with long term stability and shelf-life up to 5 years. PCFs may also be used as health restorative ingredients in cosmetic products. The outcome of probiotics CFT? stands as an advantage to the food and pharmaceutical industries, regarding the formulation of novel products with unadulterated sensory characteristics of origin. Hence, PCFs are being characterized here as “novel nutraceutical ingredients” for health maintenance in both humans and animals.展开更多
