TRAIL death receptor-4, decoy receptor-1 and decoy receptor-2 expression on CD8+ T cells correlate with the disease severity in patients with rheumatoid arthritis.

Background: Rheumatoid Arthritis (RA) is a chronic autoimmune inflammatory disorder. Although the pathogenesis of disease is unclear, it is well known that T cells play a major role in both development and perpetuation of RA through activating macrophages and B cells. Since the lack of TNF-Related Apoptosis Inducing Ligand (TRAIL) expression resulted in defective thymocyte apoptosis leading to an autoimmune disease, we explored evidence for alterations in TRAIL/TRAIL receptor expression on peripheral T lymphocytes in the molecular mechanism of RA development.

A case of primary Sjögren's syndrome with pulmonary-limited Wegener's granulomatosis.

A 60-year-old woman had a history of dyspnea for 5-6 weeks. The chest radiograph and computed tomography scans revealed bilateral patchy reticulonodular pattern. The patient had positive test results for antineutrophil cytoplasmic antibody against proteinase-3 (c-ANCA), antinuclear antibody and anti-Ro antibody.

Retrospective review of 216 patients who underwent minor labial salivary gland biopsy in last 5 years was performed. Results of the patients with diagnosis of pSS were compared with the patients failing to fill the classification criteria of pSS.

Aging and the immune system.

Aging is associated with many physiological changes in a variety of organ systems. Nevertheless, considerable interest has centred on the possibility that age-related immunological changes may play a key "master" role in regulating many, if not all, subsequent events. A growing body of data, some of it highlighted in this review, supports the notion that host resistance in general is changed in both a qualitative and quantitative manner with age, though the biochemical mechanism(s) underlying such changes are not unique to the immune system per se.

Serum transforming growth factor-beta1(TGF-beta1) in patients with cirrhosis, chronic hepatitis B and chronic hepatitis C [corrected].

Chronic liver disease and cirrhosis are two of the most important health problems according to current gastroenterology literature. Based on the recent developments in the field of immunology, advanced follow-up and treatment modalities have been introduced for these disorders. Immune defence against viral infections depends on effective cellular immune responses derived mainly from Th1-related cytokines.

Biochemical and morphological characteristics of selenite-induced apoptosis in human hepatoma Hep G2 cells.

Selenium is a cellular growth inhibitor in many mammary tumor cells. To comprehend the mechanism for the selenium-induced cell death, we examined the effects of sodium selenite, which has been one of the most extensively investigated selenium compounds, in human hepatoma Hep G2 cells.Cell viability gradually decreased after treatment with sodium selenite within the concentration range of 10-50 microM.

Fundamental principals of tumor necrosis factor-alpha gene therapy approach and implications for patients with lung carcinoma.

Apoptosis, known as programmed cell death, is defined as a cell's preferred form of death under hectic conditions through genetically conserved and complex pathways. There is a decisive balance between stimulatory and inhibitory signaling pathways to maintain homeostasis in cells. In order to shift the balance towards apoptosis, the modulation of both apoptotic and anti-apoptotic pathways represents an attractive target for cancer therapeutics.

A patient with hyper-IgD syndrome in Antalya, Turkey.

Hyper-IgD syndrome is a periodic fever syndrome that presents with recurrent episodes of high fever accompanied by lymphadenopathy, abdominal distress, arthralgias or arthritis, headache and skin lesions. The diagnosis is based on clinical grounds and elevated serum IgD levels (>100 U/ml), but requires a high index of suspicion, and a mevalonate kinase enzyme defect. Most patients are from western Europe but there are others identified in other countries.
