The dysregulation of astrocytic function can also impair the uptake of neurotransmitters such as glutamate, leading to excitotoxicity and neuronal damage (Kamal et al

The L in L-Glutathione is pointed at a particular chemical configuration of the amino acids, which is known to make up glutathione

therefore, they present clinically with longitudinal melanonychia.7,16 However, up to 25% of subungual melanocytes originate in the nail bed and, in view of the limited melanin synthesis by these melanocytes, they are often amelanotic.2,7,11,14,21 Given their low density and quiescent state, it may be difficult to visualize nail melanocytes with hematoxylin-eosin staining, and an immunohistochemical technique is needed.7,18,20,22 Cytoplasmic staining with melan-A and HMB45 is less precise and may even stain keratinocytes in lesions with a very active pigment synthesis.7,20,23,24 Nuclear stains, such as MiTF and SOX10, are cleaner and can more exactly determine melanocyte density and site in the epithelial layers.7,20,23,24 Nail melanocytes do not stain well with S100 and so its use should be limited.7,9,11,13,16,20 Nail Biopsy Techniques One of the main reasons, if not the main reason, for performing a biopsy of the nail apparatus is to rule out subungual melanoma.7,16,19,25 There are many different techniques and to select the most appropriate we should bear in mind both the need to obtain a usable specimen for study and the technical difficulty and risk of permanent nail dystrophy.2,11,14,16,25 Taking into account that most melanocytic lesions lie in the nail matrix, this structure should be included in almost all cases
