Nicotinic acid – From vitamin B3 to precision metabolism

Nicotinic acid – From vitamin B3 to precision metabolism

Nicotinic acid has evolved from a pellagra-curing vitamin to a context‑dependent metabolic modulator, linking vitamin B₃ biology with NAD⁺ metabolism, lipid regulation, immunity, and host–microbiome interactions. Its history and mechanisms exemplify how nutritional discoveries have shaped modern precision approaches to cardiometabolic and inflammatory disease.

cAMP – a currency of cell signaling

cAMP – a currency of cell signaling

Cyclic adenosine monophosphate (cAMP) is a universal second messenger which translates extracellular cues into cellular responses regulating metabolism, gene expression, neurobiology, and immunity. Dysregulated cAMP signaling contributes to cancer, inflammation, and neurological disorders, making it a key target in precision medicine.
