title: Which T cells cause psoriasis?
abstract: Today, T cells appear to be the main protagonists in the pathogenesis of psoriasis vulgaris. This article summarizes how T cells might contribute to the generation of psoriatic skin lesions. It discusses the preferential T cell receptor usage and the putative mode of T cell activation in psoriatic skin lesions, and how streptococcal throat infections could be involved in disease manifestations. The results are integrated into a pathogenetic concept which considers psoriasis as a T-cell mediated autoimmune disorder.
