Keratohyalin
Keratohyalin ist ein chemisch nicht genau definiertes Eiweiß, das bei der Verhornung in der Körner- (Stratum granulosum) und Stachelzellschicht (Stratum spinosum) von Epithelien in Form kleiner Körnchen (Granula) innerhalb der Zellen angesammelt wird. Keratohyalin enthält keine Sulfhydrylgruppen bzw. Disulfid-Brücken. Im Zuge der weiteren Verhornung wird es in Eleidin und schließlich zu Keratin umgewandelt. Das Keratin wird in das Stratum lucidum befördert, weshalb diese Schicht als sehr dünner Strich erscheint. Es dient dem Schutz gegen Wasserverlust.

Keratohyalin granules are heterogeneous in ridged and non-ridged human skin evidence from anti-filaggrin immunogold labelling of normal skin and skin of autosomal dominant ichthyosis vulgaris patients - G?nzel, Weidenthaler, B, Hausser, Anton-Lamprecht, K
Keratohyalin granules are heterogeneous in ridged and non-ridged human skin: evidence from anti-filaggrin immunogold labelling of normal skin and skin of autosomal dominant ichthyosis vulgaris patients. G?nzel S, Weidenthaler B, Hausser I, Anton-Lamprecht I. Institut f?r Ultrastrukturforschu ng der Haut, Ruprecht-Karls-Unive rsit?t Heidelberg, Federal Republic of Germany. Recent biochemical and morphological investigations have provided evidence for a heterogeneous composition of Keratohyalin in human skin. A major component is filaggrin. In interfollicular epidermis the heterogeneity of Keratohyalin is not directly visible, whereas in normal ridged skin bicomponent Keratohyalin is revealed by electron microscopy. Skin biopsies of ridged and non-ridged skin of normal individuals and patients with autosomal dominant ichthyosis vulgaris (ADI)--characterized by defective Keratohyalin synthesis and lack of filaggrin--were investigated by routine transmission electron microscopy and immunogold postembedding techniques using a commercial monoclonal anti-filaggrin antibody. In normal interfollicular epidermis filaggrin labelling was demonstrated on Keratohyalin granules and in the lowermost cornified cells, whereas in ADI patients crumbly Keratohyalin granules were present that did not show specific labelling for filaggrin. In normal ridged skin only the major (more electron-dense) component reacted with anti-filaggrin, whereas the attached (less electron-dense) component did not react. Ridged skin of ADI patients contained globular Keratohyalin that did not react with anti-filaggrin, thus corresponding to the attached Keratohyalin component in normal ridged skin. Our results provide a visible counterpart to the recent biochemical investigations of Keratohyalin protein heterogeneity and contribute to the understanding of terminal differentiation in human skin and of the defective Keratohyalin synthesis in ADI.
