Acne and Stress: Impact of Catecholamines on Cutibacterium acnes

Cutibacterium acnes (former Propionibacterium acnes), is a bacterium characterized by high genomic variability with four subtypes and six major ribotypes. Skin is the largest neuroendocrine organ of the human body and many cutaneous hormones and neurohormones can modulate bacterial physiology. In the present study, we investigated the effect of catecholamines, i.e. epinephrine (Epi) and norepinephrine (Nepi), on two representative strains of C....
