Their expression is particularly high in hosts frequently exposed to microorganisms, where AMPs play a key role in innate immune responses. Insects represent one of the richest natural sources of AMPs. Over their long evolutionary history, they have developed a highly efficient immune system with AMPs playing a central role in defense against pathogens, enabling them to colonize various habitats. In recent years, interest in AMPs has significantly increased due to the emergence of antibiotic resistance, positioning these peptides as potential therapeutic alternatives for treating infections caused by multi-resistant pathogens. In this study, we investigated the antimicrobial activity of peptide fractions extracted from the hemolymph of Hermetia illucens larvae (Diptera, Stratiomyidae), an insect known for its high expression of AMPs. Larvae were injected separately with either Escherichia coli (Gram-negative) or Micrococcus flavus (Gram-positive), and hemolymph was collected 24 h post-infection, as well as from uninfected larvae. Antimicrobial activity was assessed through microbiological assays, including both agar diffusion tests and microdilution assays. Results demonstrated significant activity against pathogenic bacterial strains, including antibiotic-resistant ones. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined for each experimental condition. MIC values ranged from 0.023 to 0.375 µg·µL⁻<sup>1</sup>, while MBC values ranged from 0.187 to 0.750 µg·µL⁻<sup>1</sup>, depending on the bacterial strain and the infection treatment group.

This study explored whether probiotic supplementation with Lactobacillus rhamnosus (L. rhamnosus) and/or Lactobacillus plantarum (L. plantarum) could mitigate anxiety- and depressive-like behaviors in H. pylori-infected rats. In addition, specific biochemical mechanisms underlying H. pylori and probiotic effects were investigated. Rats were infected with H. pylori and treated with L. rhamnosus, L. plantarum, or both probiotics via oral gavage. Anxiety- and depression-like behaviors were assessed using open field, elevated plus maze, forced swimming, and marble burying tests. Oxidative stress markers, inflammatory cytokines, brain-derived neurotrophic factor (BDNF), serotonergic function, and corticosterone level were quantified in cortical tissues. Both L. rhamnosus and L. plantarum, particularly when co-administered, potently reversed the anxiogenic and depressogenic effects of H. pylori infection. These behavioral rescues were paralleled by normalization of dysregulated cortical oxidative and inflammatory parameters including suppressed anti-inflammatory cytokine IL-10 and reduced antioxidant defenses. Similarly, H. pylori-induced attenuation of neurotrophic capacity and serotonin availability alongside heightened corticosterone level were all opposed by L. rhamnosus and L. plantarum supplementation. Our integrative methodology provided pivotal evidence that multispecies probiotic intervention with L. plantarum and L. rhamnosus alleviates anxiety/depressive-like symptoms in a preclinical model of gastrointestinal inflammation. We propose that adjunctive probiotic therapy could promote the behavioral resilience by optimizing the redox regulation, suppression of inflammatory response, enhancement of neurotrophic support, and maintenance of serotonergic transmission in brain cortex.

In compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards, a systematic search of the online bibliographic database PubMed from its launch until January 2025 was carried out. There were 267 papers that qualified for inclusion. Traditionally recognized for gut health, Bifidobacterium has also shown potential in modulating skin health and metabolic functions by stimulating GLP-1 secretion. GLP-1 plays a crucial role in regulating blood glucose levels, promoting DNA repair, and exhibiting neuroprotective effects, thereby addressing oxidative stress and cellular senescence. In INS-1 pancreatic beta cells, GLP-1 treatment reduced the oxidative damage caused by tert-butyl hydroperoxide. GLP-1-treated cells showed increased glutathione cellular concentrations and the activity of its related enzymes, including glutathione reductase and peroxidase. The cAMP-mediated PKA/extracellular signal-regulated kinase (ERK) pathway also contributes to the regulation of antioxidant enzymes, which in turn aids in the prevention of skin aging. Recent findings suggest that Bifidobacterium also enhances glucose tolerance and insulin sensitivity, indicating therapeutic potential for diabetes management.

Strain C-1 demonstrated robust tolerance to various adverse environments, maintaining 102.6% viability at pH 6.0 for 3 h and surviving in 10.0% NaCl, although it exhibited poor tolerance to high concentrations of bile salts. The strain showed sensitivity to most antibiotics, possessed strong auto-aggregating, hydrophobic properties and adhesion capacity, besides it can adhere to pathogenic microorganisms and inhibit the growth of pathogenic bacteria.
