[Role of Toll-like receptors in etiology of selected diseases of the skin].
Toll-like receptors (TLR) play an important role in anti-infectious defense of organisms. So far in humans 10 receptors have been identified. They were classified into five different subfamilies according to their affinity to characteristic ligands. Every receptor has a similar structure (extracellular part, intramembrane part and cytoplasmic part), irrespective of a type of the ligands with which it reacts. Ligands are present on many cell types, including on those which make up the skin. That is why Toll-like receptors are an important part of the cutaneous, non-specific immunologic response. In the review problems associated with the structure and functions of Toll-like receptors are presented. Moreover, the latest information about the role of TLR in the etiology of some dermatoses (psoriasis, atopic dermatitis, acne vulgaris, rosacea, infections, systemic lupus erythematosus, mycosis fungoides) is discussed. In addition, therapeutic implications are described.
