<\/p>\ngene codifies exonuclease that was related to the maintenance of genomic stability, and certain repairmen mechanisms such as DNA degradation. On previous studies, the research group saw that this protein made a presence specifically on the skin. Moreover, the study of deficient mice phenotype for this protein shows that the loss of<\/p>\n
<\/span>TREX2<\/em><\/p>\ncreates a higher susceptibility to UV-induced skin carcinogenesis.<\/span><\/p>\n
To go further in the TREX2<\/p>\n<\/em>role in homeostasis and skin pathogenesis, the researchers wanted to see the role of this nuclease on psoriasis. At the beginning, they analyzed different biopsies of patients and people without the disease. Later, using different mice models of psoriasis, they compared the evolution of the disease on normal and deficient mice by<\/p>\n
TREX2<\/p>\n<\/em>to infer the function of this molecule. \u201cThe results show that<\/p>\n
TREX2<\/em><\/p>\nwould have a relevant role in the DNA degradation on psoriasis epidermis, provoking the characteristic inflammatory response of this disease\u201d, says Concepci\u00f3 Soler, responsible of the study and professor at the Department of Pathology and Experimental Therapeutics of the University of Barcelona. The study shows that skin with psoriasis has a high increase of the<\/p>\n<\/span>TREX2<\/em><\/p>\nexpression that focuses on the cell nucleus of keratinocyte \u2013the most abundant cells on the skin- which are spreading, dying and differentiating in a strange way. Therefore, the results suggest an important role of the processing DNA gene. \u201cIn our study, we highlight the essential role of<\/p>\n
<\/span>TREX2<\/em><\/p>\npromoting DNA degradation and its consequent cell death of keratinocyte, influencing the skin immune response. The release of several signals by skin cells that are dying contributes to the creation and spreading of the chronic immune response and hyper-proliferation and irregular differentiation of epidermis\u201d, says Joan Manils, first author of the study and member of the mentioned department and post-doctorate researcher at the Trinity Biomedical Sciences Institute (Ireland).<\/span> The results show<\/span><\/p>\nTREX2<\/p>\n
<\/em>as a potential therapeutic target to tackle this disease with a different and more focused strategy. \u201cMost of the current treatments are aimed at blocking the action of the immune system and if they have good results, these treatments are chronic and involve the immune response of the sick person\u201d, says Francisco Ciruela, co-author of the study, Professor at the Department of Pathology and Experimental Therapeutics of the UB and Head of the Research Group on Neuropharmacology and Pain at IDIBELL.<\/span> The next objective of the researchers is to decode the action mechanism of<\/p>\n<\/span>TREX2<\/p>\n<\/em>in the development and maintenance of psoriasis, so as to design new therapeutic strategies for the treatment of this disease.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"A study published in Journal of Investigative Dermatology has identified a potential therapeutic target for the treatment of psoriasis, a chronic inflammatory disease of the skin that affects up to a 2% of the population and which has still no cure.
