Moreover, blocking sphingomyelinase activation with drugs [e.g., amitriptyline for ASM, or GW4869 for neutral sphingomyelinase (nSMase)] or siRNA (e.g., NSM2/SMPD3 siRNA)prevented CD150 from reaching the surface, which significantly reduced measles entry (22)
The hypodermis is also limited.9,11,14,16 The nail is a special site in terms of melanocyte distribution.7,11,14,16,18 The normal number of melanocytes in the nail apparatus is almost 6 times lower than observed in other sites: 200/mm2 compared with 1150/mm2 in normal skin.7,9,11,14,20 Melanocytes are scarce in the eponychium and nail bed (0 to 50/mm2), are in a quiescent state, and are mainly found in the basal layers of the epithelium.7,11,14,16,18 In the matrix, the melanocyte density is somewhat higher (100 to 200/mm2) and the melanocytes may be found in the suprabasal layers, although this is not considered a pathologic finding, particularly in the proximal matrix.7,15,16,18,20 The melanocytes in the proximal matrix are also in a quiescent state and hardly produce any melanin, whereas those in the distal matrix are more active (approximately 50% produce melanin).7,11,16 For this reason, most pigmented melanocytic lesions of the nail apparatus arise in the matrix, and particularly in the distal part (up to 85%)
