Association of mesangial IgM with IgM deposits in the macula densa: an indication of non-specific macromolecule transport rather than immune reactant?
These results confirm the association of IgM deposits in the macula densa with mesangial IgM, and suggest that mesangial IgM deposits may be a reflection of non-specific macromolecule transport rather than an immune reactant.
Neither L-DOPA nor its radiolabeled analog fluoroDOPA is metabolized or accumulates specifically in dopaminergic or even catecholaminergic neurons. Substantial dopamine production within serotonin and norepinephrine neurons may play a role in either therapeutic effects or adverse effects of therapy with L-DOPA.
