We explored how Lactobacillus rhamnosus DNA might affect allergic responses linked to Th2 polarization. Using a specific protocol in mice, we administered LR-DNA daily for five days and observed its impact on intestinal cells. The results showed that LR-DNA increased PD-L1 expression in these cells, which then helped trigger the death of Th2 cells.
Importantly, while we found promising effects, the study suggests that just the DNA from the probiotic—not the live bacteria—was effective in reducing allergic responses.

We examined how probiotics, especially Lactobacillus rhamnosus, can improve treatments for food allergies through allergen-specific immunotherapy (FA-AIT). These helpful bacteria promote better immune responses, leading to increased tolerance. Clinical trials revealed that combining Lactobacillus rhamnosus with peanut immunotherapy led to better desensitization rates and positive immune changes.
While FA-AIT remains under study, integrating probiotics into these treatments appears promising for achieving lasting relief from allergies and improving patient well-being.

Lr improves lung inflammation managementLactobacillus rhamnosus Modulates Lung Inflammation and Mitigates Gut Dysbiosis in a Murine Model of Asthma-COPD Overlap Syndrome.
High relevance for ACOS treatment
We sought to understand how Lactobacillus rhamnosus (Lr) influences lung inflammation and gut health in asthma-COPD overlap syndrome (ACOS). In an experimental study with mice, we introduced Lr treatment after inducing ACOS.
Our findings indicated that Lr treatment reduced lung inflammation, bronchial hyperreactivity, and improved gut microbiota diversity. Specifically, Lr lowered the levels of pro-inflammatory cytokines and restored beneficial immune markers. This study reveals that Lr could play a role in managing symptoms of ACOS by modulating both lung inflammation and gut dysbiosis.

We explored the effect of Lactobacillus rhamnosus 76 (LR76) on mice suffering from allergies triggered by ovalbumin.
In our study, LR76 helped reduce signs of airway inflammation and improved mucus secretion by affecting certain pathways involved in immune response.
Mice that received LR76 showed a decrease in multiple inflammatory markers, indicating a potential benefit of this probiotic on allergy-related symptoms. However, while promising, we must note that this study was conducted in animals, and results may differ in humans.

Probiotic reduces allergy symptoms[The results of the use of a combined probiotic ( and spp. ВB-12) in children with gastrointestinal and skin manifestations of food allergy].
Moderately relevant for allergy treatment
We assessed the impact of a combined probiotic, including Lactobacillus rhamnosus, on children with food allergies. In a study involving 92 children aged 4 to 5 years, half received the probiotic for 21 days while the control group did not.
Results showed a significant reduction in skin and gastrointestinal symptoms in those using the probiotic, alongside decreased levels of the allergy marker IgE. Although some symptoms returned over time, the overall severity remained lower than at the start.
Our findings suggest that this probiotic could improve allergy symptoms, supporting its potential as a treatment option for children.
