Lactococcus lactis shows promise for T1DMOral administration of Lactococcus lactis-expressing heat shock protein 65 and tandemly repeated IA2P2 prevents type 1 diabetes in NOD mice.
High relevance for autoimmune research
We investigated the potential of Lactococcus lactis, a safe bacterial strain, to deliver protective proteins for preventing type 1 diabetes (T1DM) in NOD mice. Our study used two specially engineered strains that expressed a specific protein.
We found that oral administration of these Lactococcus lactis strains helped stop high blood sugar, enhanced glucose tolerance, and reduced inflammation in the pancreas. This occurred by suppressing certain auto-reactive T cells and encouraging healthy immune responses. Our results suggest that this method could effectively help prevent T1DM in these mice.

We examined how a special probiotic mix, known as IRT5, affects autoimmune diabetes in non-obese diabetic (NOD) mice. Administered frequently over 36 weeks, this combination not only reduced diabetes incidence but also lowered insulitis scores and increased insulin-producing β-cell mass.
Additionally, IRT5 improved gut health and changed the makeup of immune cells in the pancreas and intestines. While some immune responses stayed the same, the shift towards more gut-focused regulatory T cells suggests it could be a promising treatment for type 1 diabetes.

Synbiotics improve rheumatoid arthritis symptomsSynbiotic supplementation and the effects on clinical and metabolic responses in patients with rheumatoid arthritis: a randomised, double-blind, placebo-controlled trial.
High relevance; significant findings
We investigated how synbiotic supplementation affects patients with rheumatoid arthritis (RA). In an 8-week, randomized, double-blind trial involving 54 participants, we compared the outcomes of those taking synbiotic capsules with a placebo group.
After the trial, those who received synbiotics showed a significant drop in inflammation markers and pain levels. Additionally, improvements were observed in insulin resistance and overall metabolic responses.
These findings suggest that synbiotics might benefit individuals managing RA by reducing inflammation and enhancing metabolic health.

We explored how specific Lactobacillus acidophilus strains can impact autoimmune disorders by reducing leptin production in mice. In our study, we compared the effects of CBA4P and other lactobacilli on adipocytes from mice sensitive to Th1 immune diseases.
Results showed that CBA4P significantly lowered leptin levels and inhibited the activation of immune lymphocytes in the SJL mouse strain. This suggests that CBA4P might help manage Th1-related inflammatory conditions, representing a potentially valuable probiotic option for autoimmune control.

Bifidobacterium longum aids thyroid functionProbiotic Bifidobacterium longum supplied with methimazole improved the thyroid function of Graves' disease patients through the gut-thyroid axis.
High relevance due to findings
Our study investigated how Bifidobacterium longum, paired with methimazole, affects thyroid function in Graves' disease patients. Over six months, we divided participants into distinct treatment groups.
While methimazole alone improved thyroid health markers, it didn’t significantly lower the thyrotropin receptor antibody, an important indicator of potential disease recurrence. On the other hand, those receiving Bifidobacterium longum along with methimazole showed notable improvements, with TRAb levels returning to normal.
This suggests that probiotics might positively influence thyroid function by altering gut microbiota and metabolites, linking the gut and thyroid effectively.
