probiotic-research
Plant probiotic research investigates beneficial microorganisms—such as certain bacteria and fungi—that colonize roots, leaves, or seeds and form mutually beneficial relationships with their host plants. These microbes can enhance nutrient uptake, boost resistance to pathogens and environmental stress, and promote overall growth, offering a natural alternative to synthetic fertilizers and pesticides. Understanding these plant-microbe interactions is increasingly vital for developing sustainable agricultural practices that improve crop resilience and yield.

A probiotic yeast called Saccharomyces boulardii reduced brain inflammation and protected memory-related neurons in rats exposed to a toxin that mimics Alzheimer's disease conditions. It did this by dampening inflammatory signals in the hippocampus, likely through the gut-brain axis rather than by blocking the initial inflammation trigger.
Saccharomyces boulardii pre-treatment significantly reduced NF-κB and IL-1β protein levels in the hippocampus of LPS-treated rats
Probiotic treatment protected neurons in the hippocampal CA1 region from LPS-induced cell death, confirmed by Nissl staining
Sb partially improved spatial learning deficits but acted downstream of the TLR4 receptor, not by blocking TLR4 directly
