Sympathoadrenergic mechanisms may play a role in multiple sclerosis (MS). We examined
catecholamine (CA) levels and production and tyrosine hydroxylase (TH) expression in …

Although it is now established that immunocompetent cells produce catecholamines (CA),
which in turn may act as autocrine/paracrine mediators, little is known about the …

Circumstantial evidence suggests the involvement of sympathoadrenergic mechanisms in
the progress of multiple sclerosis (MS). We studied peripheral blood lymphocytes from MS …

Using immunocytochemistry coupled to fluorescence and electron microscopy, we
investigated the expression and ultrastructural localization of tyrosine hydroxylase (TH, EC …

Catecholamines usually are found in neurons and chromaffin cells of mammals. In this
study, surprisingly high levels of the epinephrine synthesizing enzyme phenylethanolamine …
