SummaryMultiple sclerosis (MS) is a demyelinating inflammatory disorder of the central nervous system (CNS), which involves autoimmune responses to myelin antigens. Studies in experimental autoimmune encephalomyelitis (EAE), an animal model for MS, have provided convincing evidence that T cells specific for self-antigens mediate pathology in these diseases.

Summary
The immunopathology of type 1 diabetes (T1D) has proved difficult to study in man because of the limited availability of appropriate samples, but we now report a detailed study charting the evolution of insulitis in human T1D. Pancreas samples removed post-mortem from 29 patients (mean age 11·7 years) with recent-onset T1D were analysed by im...... hiện toàn bộ Tumour necrosis factor (TNF) gene polymorphism influences TNF-α production in lipopolysaccharide (LPS)-stimulated whole blood cell culture in healthy humans Tập 113 Số 3 - Trang 401-406 - 2001

SUMMARYTNF-α is involved in infectious and immuno-inflammatory diseases. Different individuals may have different capacities for TNF-α production. This might determine a predisposition to develop some complications or phenotypes of these diseases. The aims of our study were to assess the inter-individual variability of TNF-α production and to correlate this variabi...... hiện toàn bộ A marked difference in pathogenesis and immune response induced by differentMycobacterium tuberculosisgenotypes Tập 133 Số 1 - Trang 30-37 - 2003

SUMMARYIn the last decade, an unprecedented genetic diversity has been disclosed among Mycobacterium tuberculosis strains found worldwide. However, well-conserved genotypes seem to prevail in areas with high incidence of tuberculosis. As this may be related to selective advantages, such as advanced mechanisms to circumvent [M. bovis Bacille Calmette–Guerin (BCG)-in...... hiện toàn bộ Quantitative analysis of peripheral blood Th0, Th1, Th2 and the Th1:Th2 cell ratio during normal human pregnancy and preeclampsia Tập 117 Số 3 - Trang 550-555 - 2001

SUMMARYWe calculated the percentage of Th1, Th2, Th0 cells and the Th1:Th2 cell ratio of peripheral blood from normal pregnant subjects and preeclampsia patients using flow cytometry which can analyse both the surface marker, CD4, and intracellular cytokines, interleukin (IL)-4 and interferon (IFN)-γ. In normal pregnancy, the percentage of Th1 cells was significant...... hiện toàn bộ Immunopathogenic mechanisms in psoriasis Tập 135 Số 1 - Trang 1-8 - 2003

SUMMARYPsoriasis is a common autoimmune skin disease characterized by T cell-mediated hyperproliferation of keratinocytes. The disease has a strong but complex genetic background with a concordance of approximately 60% in monozygotic twins, and recent linkage and high resolution association studies indicate that HLA-Cw*0602 is itself a major susceptibility allele f...... hiện toàn bộ The number of human peripheral blood CD4+ CD25high regulatory T cells increases with age Tập 140 Số 3 - Trang 540-546 - 2005

SummaryAgeing is associated with evidence of immune deficiency and dysregulation. Key changes in the immune system with ageing include a progressive reduction in naive T cell output associated with thymic involution and peripheral expansion of oligoclonal memory T cells. These features are associated with evidence of impaired immune responsiveness both in vitro and...... hiện toàn bộ
