Ceramides are synthesized during epidermal differentiation
and accumulate within the interstices of the stratum corneum, where
they represent critical components of the epidermal permeability
barrier. Excess cellular ceramide can trigger antimitogenic signals
and induce apoptosis, and the ceramide metabolites sphingosine and
sphingosine-1-phosphate (S1P) are important bioregulatory
molecules. Ceramide hydrolysis in the nucleated cell layers
regulates keratinocyte proliferation and apoptosis in response to
external stress. Ceramide hydrolysis also occurs at the stratum
corneum, releasing free sphingoid base that functions as an
endogenous antimicrobial agent. ACER1 is highly expressed in
epidermis and catalyzes the hydrolysis of very long chain ceramides
to generate sphingosine (Houben et al., 2006 [PubMed 16477081]; Sun
et al., 2008 [PubMed 17713573]).1) Sun, W., et al. J. Invest. Dermatol. 128(2):389-397(2008)
