Various aspects concerning the L-dopa uptake mechanism into human epidermal Langerhans cells (LC) and the energy metabolism of epidermis have been examined. The study is based on the discovery of a new amino acid transport system in human epidermal LC.

We have characterized a stereospecific transport mechanism for L-dopa into human epidermal Langerhans cells (LCs). It is different from any other amino acid transport system. It is highly concentrative, largely pH-independent, and independent of exogenous Na+, glucose and oxygen, and
B Falck et al.
Acta dermato-venereologica, 73(3), 197-199 (1993-06-01)
We recently reported the existence of two kinds of human epidermal Langerhans' cells (LC), one which can take up and accumulate L-dopa and one which cannot. The dopa(+) LC take up L-dopa by carrier-mediated exchange diffusion, that is, the influx
