Description

Clarification of Terminology

  • Lcr35: A probiotic strain used in clinical applications for over 50 years, primarily to restore microbial balance in vaginal, intestinal, and immune systems .

  • Antibody: A protein produced by the immune system to neutralize pathogens. No studies associate Lcr35 with antibody production or monoclonal antibody development.

Immunomodulatory Mechanisms

MechanismEffect ObservedCitation
Cytokine ModulationIncreased IL-8, IL-1β, and HBD-2; reduced SLPI in vaginal epithelial cells
Dendritic Cell ActivationSemi-maturation of DCs, increased TNFα, IL-12, and IL-23; decreased IL-10
T Regulatory Cell InductionIncreased CD4+CD25+Foxp3+ Treg cells in asthma models

Therapeutic Applications

  • Vaginal Health: Inhibits Gardnerella vaginalis by modulating SLPI and enhancing epithelial defenses .

  • Asthma Prevention: Attenuates airway inflammation via Th2 cytokine suppression (IL-4, IL-5, IL-13) and Treg cell induction .

  • Antifungal Activity: Reduces Candida albicans adhesion and biofilm formation via DAF-16/FOXO pathway activation .

Efficacy in Irritable Bowel Syndrome (IBS)

ParameterPlacebo Group (n=25)Lcr35 Group (n=25)P-value
IBS Severity Score-109.4 ± 93.1-56.8 ± 43.9NS
Abdominal Pain-61.0 ± 96.0-27.5 ± 31.6NS
NS = Not significant

Mechanistic Pathways

  • p38 MAPK Signaling: Critical for Lcr35’s anti-Candida effects in C. elegans .

  • NF-κB Inhibition: Mediated via SLPI downregulation in vaginal infections .

  • FOXO3a/DAF-16 Activation: Linked to longevity and antifungal responses .
