Local tetrahydrobiopterin administration augments cutaneous vasoconstriction in aged humans

Reflex vasoconstriction (VC) is attenuated in aged skin resulting in greater skin blood flow and heat loss during cold exposure. We hypothesized that adrenergic function is compromised due to depletion of tetrahydrobiopterin (BH(4)), an essential cofactor required for catecholamine synthesis, and th...
