Diseases of autoimmune connective tissues occur in such a way by a preclinical asymptomatic self-immunity. Type I interferons have a crucial role in the progression of established autoimmune diseases. The cellular source and regulation of disease initiation of these cytokines are unclear, but dendritic cells of plasmacytoids have been thought to contribute to the production of excessive interferon type I. Here, we show that in Preclinical autoimmunity and systemic systemic erythematosus established, the dendritic cells of plasmacytoids are not efficient cells, have lost the capacity of the production of cytokine to toll mediation and do not induce the activation of the T cell, independent of The activity of the disease and blood interferon signature. In addition, the dendritic cells of plasmacytoids have an indicative transcriptional signature of cell stress and senescence accompanied by an increase in telomere erosion.
In preclinical self-immunity, we show a marked enrichment of an interferon signature in the skin without infiltrating immune cells, but with interferon-κ production by keratinocytes. In conclusion, non-hematopoietic cellular sources, rather than dendritic cells of plasmacytoids, are responsible for interferon production before clinical self-immunity. The immune system is responsible for identifying malignant cells to eliminate or prevent the propagation of cancer. This involves a complex orchestration of many types of immune cells that together recognize different aspects of the transformation and growth of the tumor. In response, tumors have developed mechanisms to circumvent the immune attack. Type I interferons (IFN-IS) are a class of preflammatory cytokines produced in response to viruses and other environmental stressors.
The IFN-is also emerge as essential pilots of antitumor immunity, stimulating the immune cell capacity for the elimination of tumor cells. However, a more complex role for IFN-is produced, as prolonged stimulation can promote information feedback mechanisms that contribute to immune depletion and other deleterious effects that directly or indirectly or indirectly the cancer cells. to escape immune clearance. We examine the fundamental and opposing functions of the IFN – can modulate the growth of the tumor and the impact of immune function and finally the way these functions can be exploited for the design of new cancer treatments.
The key roles of interferon lambda in human molecular defense against respiratory viral infections
Interferons (IFN) are crucial for the innate immune response. A little over two decades two decades ago, a new type of IFN has been discovered: IFN Lambda (IFN type III). As the other IFN, the IFN type III displays the antiviral activity against a wide variety of infections, they induce the expression of antiviral genes and stimulated by interferon (MX1, OAS, IFITM1) and have activities immunodolory makers that shape adaptive immune responses.
Unlike the other IFN, the IFN type III signal through distinct receptors is limited to a few types of cells, mainly mucous epithelial cells. As a result of their larger and more sustainable production in the nasal and respiratory tissues, they can determine the result of respiratory infections. This examination focuses on the role of IFN-λ in the pathogenesis of respiratory viral infections, with the flu as a great example. The influenza virus is a major public health problem, causing up half a million fatal infections each year. In addition, the virus was the cause of four pandemics in the last century.
Although IFN-λ is increasingly tested in antiviral therapy, they can have a negative influence on the recovery of epithelial tissues and increase the risk of secondary bacterial infections. Therefore, the expression IFN-λ deserves increased monitoring as a key factor in the immune response of the host to infection.
Functionally impaired plasmacytoid dendritic cells and non-haematopoietic sources of type I interferon characterize human autoimmunity
An observational study of the real world of drug use and clinical outcomes of antivirals of direct action and interferon therapy for the treatment of hepatitis C in Taiwan
Objective: In this study, we have studied the use of direct action antivirals (DAAS), medical expenses and clinical outcomes since the initiation of national health insurance coverage in Taiwan.
Methods: It was a retrospective observation study. We have obtained the National Database on Taiwan Health Insurance database in 2017. Patients diagnosed with hepatitis C with at least two visits to physicians or hospitalization were included in the study. Cases have been divided into three groups based on the type of treatment: Traditional treatment (interferon, inf), new drug treatment (DAA) and INF-Experienced (INF followed by DAAS). We compared the distributions of various cases based on individual demographic variables, hospital types and comorbidities. Trends in medical expenses by type of treatment have been estimated. We also analyzed clinical outcomes, including rehospitalization and hepatic function disorders, using a survival analysis method.
Results: Among patients with hepatitis C, the DAA Group had a significantly higher proportion of women, a more meaningful average age and a greater seriousness of the disease than Group INF. The growth rate of medical expenses was significantly lower than the DAA group. In addition, compared to the INF Group, the DAA Group and the infented group have had significantly lower rehospitalization rates and that the DAA group had a significantly lower risk of liver function disorders. In addition, plus a patient received a form of treatment, the lowest was their chance of rehospitalization and hepatic function disorders.

CONCLUSIONS: In conclusion, our results have confirmed that DAAS insurance coverage has led to better clinical results than INF, which can reduce the increases in medical expenses and the risk of rehospital and functional disorders hepatic. What we know about this subject, interferon for hepatitis C has a low efficiency with serious side effects, while the effectiveness of new oral drugs (direct action antivirals, DAAS) is high. DAAs have been approved for a Taiwan registration in December 2013 and have been covered by national health insurance since January 2017. Little things are known about the proofs of the real world related to the DAA following the coverage of DAA In Taiwan, including the use of drugs, expenses and expenses. security.
