Lactobacillus plantarum-derived indole-3-lactic acid ameliorates colorectal tumorigenesis via epigenetic regulation of CD8+ T cell immunity

Cell Metabolism, 2023
Previous studies have shown that Lactobacillus species play a role in ameliorating colorectal cancer (CRC) in a mouse model. However, the underlying mechanisms remain largely unknown. Here, we found that administration of a probiotic strain, Lactobacillus plantarum L168 and its metabolite, indole-3-lactic acid, ameliorated intestinal inflammation ...

Indole-3-lactic acid as a tryptophan metabolite produced by Bifidobacterium spp

Applied and Environmental Microbiology, 1979
Fifty-one strains of the genus Bifidobacterium have been found to accumulate indole-3-lactic acid in culture broth. The isolated metabolite was identified through mass and nuclear magnetic resonance spectroscopy. All the microorganisms tested, as resting cells, have been shown to be able to convert L-tryptophan into L-indole-3-lactic acid.

Indole-3-lactic acid is a weak auxin analogue but not an anti-auxin

Journal of Plant Growth Regulation, 1995
Indole-3-lactic acid (ILA) is a naturally occurring indole derivative, preferably detected in soil bacteria and fungi and only in low amounts in plants. T-DNA gene 5 of Agrobacterium tumefaciens was found to be involved in the synthesis of ILA in transformed plant tissues, but the physiologic relevance for ILA production in plants is unclear.

Indole‐3‐Lactic Acid Inhibits Keratinocyte Proliferation Through the Aryl Hydrocarbon Receptor in Psoriasis

The Journal of Dermatology
ABSTRACT Psoriasis is a chronic inflammatory skin disease whose pathogenesis involves dysregulation of the skin microbiota. Multiple studies have revealed alterations in microbial community composition between psoriatic lesions and healthy skin.

Oral administration of indole-3-lactic acid alleviates activity-based anorexia in female mice

Neuropharmacology
Anorexia nervosa (AN) is a severe psychiatric disorder characterized by extreme dietary restriction, pronounced weight loss, and disturbed energy metabolism. In recent years, increasing attention has been given to the role of the gut microbiota and its tryptophan-derived metabolites in modulating host neural function and feeding behavior via the gut ...

Microbiome-derived indole-3-lactic acid reduces amyloidopathy through aryl-hydrocarbon receptor activation

Brain, Behavior, and Immunity
Alzheimer's disease (AD) pathogenesis has been associated with the gut microbiome and its metabolites, though the specific mechanisms have remained unclear. In our study, we used a multi-omics approach to identify specific microbial strains and metabolites that could potentially mitigate amyloidopathy in 5xFAD mice, a widely used model for AD research.
