OBJECTIVE: To determine if the mutations in the CARD15/NOD2 gene predisposing to Crohn's disease (CD) contribute also to the genetic susceptibility to rheumatoid arthritis (RA). METHODS: The frequencies of the three commonest mutations of CARD15/NOD2 predisposing to CD (2104C > T, 2722G>C and 3020insC) were determined in 210 RA patients and 227 controls. RESULTS: Allelic frequencies of the CARD15/NOD2 mutations in RA patients (2104C>T, 2.8%; 2722G>C, 0.9%; and 3020insC, 2.4%) did not differ significantly from the controls (2104C>T, 5.3%; 2722G>C, 0.7%; and 3020insC, 1.1%). CONCLUSION: There was no evidence of association between the commonest CD CARD15/NOD2 mutations and RA susceptibility. 相似文献

DNA commission of the International Society of Forensic Genetics: recommendations on forensic analysis using Y-chromosome STRs 总被引:18,自引:0,他引:18
Gill P Brenner C Brinkmann B Budowle B Carracedo A Jobling MA de Knijff P Kayser M Krawczak M Mayr WR Morling N Olaisen B Pascali V Prinz M Roewer L Schneider PM Sajantila A Tyler-Smith C 《International journal of legal medicine》2001,114(6):305-309
During the past few years the DNA commission of the International Society of Forensic Genetics has published a series of
documents providing guidelines and recommendations concerning the application of DNA polymorphisms to the problems of human
identification. This latest report addresses a relatively new area, namely Y-chromosome polymorphisms, with particular emphasis
on short tandem repeats (STRs). This report addresses nomenclature, use of allelic ladders, population genetics and reporting
methods.

The imbalance in the ratio of Th1 and Th2 helper lymphocytes in uraemia is mediated by an increased apoptosis of Th1 subset. 总被引:2,自引:0,他引:2

BACKGROUND: In uraemia there is a reduction in the total number of T lymphocytes and an imbalance in the ratio of Th1/Th2 T-helper (Th) lymphocytes. A higher rate of apoptosis in T lymphocytes has been reported in haemodialysis patients. The aims of the present study were to assess the Th1/Th2 pattern in uraemia and to evaluate whether a relative increase in Th1 apoptosis may explain the Th1/Th2 imbalance observed in uraemic patients. METHODS: Seventeen non-dialysed uraemic patients were evaluated; eight healthy volunteers served as controls. Intracellular interferon-gamma (IFN-gamma) and interleukin-4 (IL-4) were measured by direct intracellular immunofluorescence and flow cytometry. Apoptosis was determined by flow cytometry using annexin V or TUNEL. Mechanisms of apoptosis were assessed by determination of Fas and Bcl-2 expression. RESULTS: Cell production of cytokines is significantly higher in uraemic patients than in controls. In addition, in uraemic patients only 5.1+/-2.1% of the T lymphocytes contained IFN-gamma (Th1 cells) while 61.9 +/- 14.8% contained IL-4 (Th2 cells) (P < 0.0001). The percentage of apoptosis was 29.6 +/- 6.3% and 4.7 +/- 1.6% in Th1 and Th2 lymphocytes, respectively (P < 0.001). Fas expression was higher in Th1 than in Th2 cells and the expression of Bcl-2 was lower in Th1 than in Th2 cells. The apoptosis induced by anti-Fas antibodies was similar in both types of lymphocytes. CONCLUSIONS: In uraemia there is a reduction in the proportion of Th1 lymphocytes due to a higher rate of apoptosis in this subset of lymphocytes. Th1 from uraemic patients show a higher expression of Fas and a lower expression of Bcl-2 than Th2. This makes uraemic Th1 cells more susceptible to apoptosis. The Th1/Th2 imbalance may contribute to alterations in cellular immunity observed in chronic kidney disease patients. 相似文献

The role the FAS and BCL-2 in the apoptosis of testicular cells in the contralateral testis after unilateral testicular torsion, was investigated. We compared with control group. These experiments were performed in male Wistar rats prepuberal old. FAS and BCL-2 determination is realized in cells cultures of contralateral testis. Flow cytometry and immunohistochemistry studies, using a FAS and BCL-2 specific monoclonal antibody, were utilized to value FAS y BCL-2 expression on testiculaires cells following unilateral testicular torsion. We observed an increase of expression of FAS and decrease of BCL-2 in the contralateral testis in comparison with control group. The present results may indicate that the expression of this molecules is implicated in cellular apoptosis. 相似文献

DNA typing of 8 recently described STRs on the Y chromosome was carried out by means of 2 multiplex amplification reactions for 134 unrelated males from Cantabria, a region in northern Spain. Multiplex 1 included loci DYS460 (GATA A7.1), GATA A10, GATA H4 and DYS439; multiplex 2 included DYS461 (GATA A7.2), GATA C4, DYS437 and DYS438. Haplotype diversity was found to be 99.36%, similar to that obtained with the standard 9-STR set ("minimal haplotype") of the European Y-user group (99.35%). The 13-locus haplotype resulting from the combination of the standard minimal haplotype and the 4-locus multiplex 1 showed a 99.89% diversity. Further inclusion of the 4 loci in multiplex 2 resulted in a haplotype diversity of 99.93%. The combination of the "minimal haplotype" and the multiplex 1 in the present study may be an efficient way of increasing the power of discrimination in forensic cases. 相似文献
