To characterize ab and gd TcR expression in cultured TILs from a metastatic osteogenic sar- coma.Patient and methods: TILs were isolated from a lung metastasis of an osteogenic sarcoma in a 16- year-old female patient. Culture conditions were IL- 2 and anti-CD3 MoAb+IL-2. TcR expression and surface phenotype were studied by flow cytometry. 4h-chromium release assays were used to assess cytotoxicity. Results:IL-2-expanded tumor infiltrating T-lym- phocytes contained 50% gd TcR+ cells whereas gd TcR+ cells represented 20% of T-cells in cultures expanded with anti-CD3 MoAb+IL-2. The phenotype of gd TcR+ cells was CD3+, CD16-, CD4-, CD8-, and CD29+. AnH-CD3 MoAb + IL-2-expanded TILs mediated a significant lysis of thé autologous tumor and of an allogeneic lymphoma and displayed a higher activity against thé NK-sensitive target K562. In cold target experiments, unlabeled autol- ogous tumor cells blocked thé lysis of K562, indicating that MHC-unrestricted effectors were involved in thé lysis of both targets. Conclusions: This report demonstrates thé ex- pansion of large numbers of gd TcR+ T-cells after short-term culture of TILs from a metastatic os- teosarcoma. Further studies are needed to déter- mine thé role of gd TcR+ cells in host immune responses directed against this tumor. [less ▲]

In order to study the presence of antibodies directed against Candida albicans O-linked oligomannosides (oligomannosides O) in patient sera, we have developed an enzyme-linked immunosorbent assay (ELISA) involving neoglycolipids constructed with these residues (NGLO). Oligomannosides O released by mild alkaline degradation of the C. albicans cell wall phosphopeptidomannan (PPM) contained one to seven mannose residues, among which the quantitatively major components, mannobiose and mannotriose, were shown by 1H nuclear magnetic resonance to contain exclusively alpha (1-2) linkages. The pool of oligomannosides was converted to neoglycolipids by coupling them to 4-hexadecylaniline in an equimolar reaction checked by thin-layer chromatography. We have tested against these neoantigens, coated on ELISA plates, 15 pairs of sera corresponding to individual seroconversions observed in 15 patients during the course of a mycological and serological survey of candidiasis. For all patients, seroconversions resulted in an increased level of antibodies against NGLO. A significant correlation was observed between the results of ELISA-NGLO, ELISA involving the original PPM molecule, and routine antibody detection tests, indirect immunofluorescence assay, and cocounterimmunoelectrophoresis. These results therefore demonstrate the synthesis of human antibodies reactive with oligomannosides O constitutive of the C. albicans mannan molecule which have been previously described as exhibiting an inhibitory effect on human lymphocytic proliferation.

BACKGROUND/AIMS: Recent studies have demonstrated the existence of two oestrogen receptor subtypes alpha (ORalpha) and beta (ORbeta) with significant differences of expression among organs. Since important pathologies of human eye could be linked to hormonal status, the expression of ORbeta in ocular posterior segment was sought. METHODS: Immunohistochemical localisation of ORbeta and ORalpha protein and detection of OR mRNAs by reverse transcription-polymerase chain reaction (RT-PCR) were performed in macular and extramacular regions of the retina and in the choroid on male and female donors eyes. RESULTS: ORbeta protein was localised in the ganglion cell layer and in the choroid. At the transcriptional level, mRNA for ORbeta and for ORalpha were both present. Local differences in the expression level were observed, however, suggesting the possibility of variation in the ratio of ORalpha v ORbeta. CONCLUSIONS: The coexistence of two oestrogen receptor subtypes in the human ocular posterior segment raises acute questions about their potential physiological role, but offers a perspective for preferential targeting of a specific receptor subtype.

The atmosphere–ocean general circulation models (AOGCMs) used for the IPCC 4th Assessment Report (IPCC AR4) are evaluated for the Greenland ice sheet (GrIS) current climate modelling. The most suited AOGCMs for Greenland climate simulation are then selected on the basis of comparison between the 1970–1999 outputs of the Climate of the twentieth Century experiment (20C3M) and reanalyses (ECMWF, NCEP/NCAR). This comparison indicates that the representation quality of surface parameters such as temperature and precipitation are highly correlated to the atmospheric circulation (500 hPa geopotential height) and its interannual variability (North Atlantic oscillation). The outputs of the three most suitable AOGCMs for present-day climate simulation are then used to assess the changes estimated by three IPCC greenhouse gas emissions scenarios (SRES) over the GrIS for the 2070–2099 period. Future atmospheric circulation changes are projected to dampen the zonal flow, enhance the meridional fluxes and therefore provide additional heat and moisture to the GrIS, increasing temperature over the whole ice sheet and precipitation over its northeastern area. We also show that the GrIS surface mass balance anomalies from the SRES A1B scenario amount to −300 km3/year with respect to the 1970–1999 period, leading to a global sea-level rise of 5 cm by the end of the 21st century. This work can help to select the boundaries conditions for AOGCMs-based downscaled future projections. [less ▲]

The application of IBA to cultural heritage mostly relies on the use of PIXE because of its high sensitivity and its ease of implementation at atmospheric pressure. The need for depth information not easily available with this technique has conducted to associate RBS also in external beam mode. We have progressively developed a set-up that permits such a combination of techniques either simultaneously or sequentially. The set-up is currently further improved to permit NRA measurement (depth profiles of light elements) in addition to PIXE and RBS. The coupling of all these techniques provides a wealth of information on cultural heritage objects, not easily attainable with any other single method. [less ▲]
