ABSTRACT
New molecular methods of research have greatly expanded the knowledge about the role of cytokines in several diseases, including psoriasis. The work orchestrated by these peptides is essential for the communication between resident inflammatory cells (keratinocytes and endothelial cells) and infiltrating cells (neutrophils, lymphocytes, Langerhans cells). This is a complex network due to redundancy, synergism and, sometimes, the antagonism of cytokines, which prevents full understanding of the pathogenesis of the disease. Currently, it seems premature to try to establish a main actor, but TNFalpha participates in all stages of psoriatic plaque development, as we shall see.
RESUMO
A introdução de novos métodos moleculares de investigação ampliou muito o conhecimento sobre o papel das citocinas em diversas doenças, entre elas a psoríase. O trabalho orquestrado desses polipeptídeos é fundamental na comunicação entre as células inflamatórias residentes (queratinócitos e células endoteliais) e infiltrantes (neutrófilos, linfócitos, células de Langerhans). Trata-se de uma rede complexa devido à redundância, ao sinergismo e, por vezes, ao antagonismo das citocinas, o que dificulta a compreensão da fisiopatogenia da doença a partir de um mecanismo linear. No momento atual, parece precoce tentar estabelecer um regente, mas o TNF-alfa se destaca em todos os passos do desenvolvimento da placa psoriásica, como veremos a seguir.
