The skin, the body's largest organ, is strategically located at the
interface with the external environment where it detects,
integrates and responds to a diverse range of stressors, including
solar radiation. It has already been established that the skin is
an important peripheral neuroendocrine-immune organ that is closely
networked with central regulatory systems. These capabilities
contribute to the maintenance of peripheral homeostasis.
Specifically, epidermal and dermal cells produce and respond to
classical stress neurotransmitters, neuropeptides and hormones,
production which is stimulated by ultraviolet radiation (UVR),
biological factors (infectious and non-infectious) and other
physical and chemical agents. Examples of local biologically active
products are cytokines, biogenic amines (catecholamines, histamine,
serotonin and N-acetyl-serotonin), melatonin, acetylocholine,
neuropeptides including pituitary (proopiomelanocortin-derived
ACTH, b-endorphin or MSH peptides, thyroid stimulating hormone) and
hypothalamic (corticotropin-releasing factor and related
urocortins, thyroid-releasing hormone) hormones, as well as
enkephalins and dynorphins, thyroid hormones, steroids
(glucocorticoids, mineralocorticoids, sex hormones, 7- steroids),
secosteroids, opioids and endocannabinoids. The production of these
molecules is hierarchical, organized along the algorithms of
classical neuroendocrine axes such as the hypothalamic pituitary
adrenal axis (HPA), hypothalamic-thyroid axis (HPT),
serotoninergic, melatoninergic, catecholaminergic, cholinergic,
steroid/secosteroidogenic, opioid and endocannabinoid systems.
Disruptions of these axes or of communication between them may lead
to skin and/or systemic diseases. These local neuroendocrine
networks also serve to limit the effect of noxious environmental
agents to preserve local and consequently global homeostasis.
Moreover, the skin-derived factors/systems can also activate
cutaneous nerve endings to alert the brain to changes in the
epidermal or dermal environments, or alternatively to activate
other coordinating centers by direct (spinal cord)
neurotransmission without brain involvement. Furthermore, rapid and
reciprocal communications between epidermal and dermal and adnexal
compartments are also mediated by neurotransmission including
antidromic modes of conduction. Lastly, skin cells and the skin as
an organ coordinate and/or regulate not only peripheral but also
global homeostasis.
