A 140-amino-acid presynaptic protein whose misfolding into insoluble fibrils and their deposition in Lewy bodies is the defining neuropathological hallmark of parkinsons disease and the broader family of synucleinopathies (including Lewy body dementia and multiple syste…
The most abundant mineral in the human body, with ~99% stored in bones and teeth. Calcium's biological significance extends far beyond structural support -- it is the universal second messenger in cell signaling, controlling neurotransmitter release, muscle contraction,…

Fibromyalgia (FM) is a chronic pain syndrome affecting 2-4% of the global population Heidari et al. 2017, characterized by widespread musculoskeletal pain, fatigue, cognitive dysfunction ("fibro fog"), and sleep disturbances. Conventionally attributed to central sensiti…

The community of trillions of microorganisms — bacteria, archaea, fungi (mycobiome), viruses, and bacteriophages — inhabiting the human gastrointestinal tract, with the highest density in the colon (~10¹¹ cells/g). The gut microbiome encodes 100–150 times more genes tha…
Bidirectional communication between the gut microbiota and the central nervous system, mediated by neural (vagus nerve, enteric nervous system), immune (cytokines, microglia), endocrine (HPA axis), and metabolic (SCFAs, neurotransmitter precursors, tryptophan metabolite…
Chronic nickel exposure can damage the central nervous system, causing behavioral and cognitive deficits through oxidative stress in the hippocampus and disruption of multiple neurotransmitter systems.
Phenylalanine is an essential aromatic amino acid that sits at a metabolic crossroads: it is the precursor to tyrosine (and through it to dopamine, norepinephrine, and epinephrine), a substrate for microbial conversion to cardiovascular risk metabolites, and a participa…

Tryptophan (Trp) is an essential amino acid that the human body cannot synthesize and must obtain from diet. It occupies a uniquely important position at the intersection of neuroscience, immunology, and microbial ecology because it is the sole precursor to serotonin, a…
