Abstract

New therapeutic approaches are needed to improve the cure rates in acute myeloid leukaemia (AML). The present study was designed to investigate whether: (1) cytotoxic lymphocytes could be expanded from AML patients in complete remission; (2) their signal transduction machinery was preserved; (3) these cells were capable of producing cytokines involved in the cytolytic process; and (4) these cells showed cytotoxic activity against allogeneic and autologous blasts. By co-culturing blood mononuclear cells with feeder cells, we obtained an average 5.3-fold increase in the total cell number and a 35-fold increase in natural killer (NK) cells. Expression of the zeta chain and of tyrosine kinases of the Src and Syk-ZAP families involved in the triggering of NK functions was analysed on expanded cells. The results demonstrated a signal transduction apparatus preserved and quantitatively similar to that of normal donors. After phorbol myristate acetate and ionomicin stimulation, the ability of expanded cells to produce interferon gamma and tumour necrosis factor alpha was documented. Patients' expanded cells showed a cytotoxic activity against target lines and allogeneic blasts which was similar to that of normal donors. Purification experiments indicated that the NK cell fraction was responsible for most of the lytic effect. More significantly, these cells also exerted a lytic effect against autologous blasts that could be further enhanced following incubation with low-dose interleukin 2. These findings document the possibility of expanding cytotoxic effectors with preserved signal transduction machinery and autologous killing capacity from AML patients in remission, and suggest a new potential immunotherapeutic strategy for the management of early disease recurrence or of residual disease.

Abstract

Platelet function was studied in 30 pregnant women: 14 normotensive (C), and 16 affected by pregnancy-induced hypertension (PIH). Platelet aggregometry (PA) on platelet-rich plasma according to Born was compared with the new PFA-100 System (Dade International Inc, Miami, USA). This device evaluates platelet function (expressed in seconds as closure time, CT) in anticoagulated whole blood ex vivo at high shear rates. PA (expressed as percentage of light transmission) and CT were measured at baseline and after incubation with L-Arginine (L-Arg). MANOVA for repeated measures showed that L-Arg incubation significantly decreased PA (F=7.2, P0.05) and increased CT (F=6.05, P0.05) in the whole population of pregnant women. Moreover, we analysed separately both parameters in C and in PIH subjects. No differences in PA were found in both groups, neither at baseline nor after L-Arginine incubation. In contrast, CT was significantly longer in PIH in comparison to C before (95.9 s vs. 84 s, P0.05) as well after (115 s vs. 92 s, P0.05) L-Arginine incubation. Data from PFA-100 confirm our previous reports that during pregnancy the L-Arginine: Nitric Oxide pathway regulates platelet function. In hypertensive patients a significant decrease in platelet function was found by using the PFA-100 system.

Abstract

The study of CPT invariance with the highest achievable precision in all particle sectors is of fundamental importance for physics. Equally important is the question of the gravitational acceleration of antimatter. In recent years, impressive progress has been achieved at the Low Energy Antiproton Ring (LEAR) at CERN in capturing antiprotons in specially designed Penning traps, in cooling them to energies of a few milli-electron volts, and in storing them for hours in a small volume of space. Positrons have been accumulated in large numbers in similar traps, and low energy positron or positronium beams have been generated. Finally, steady progress has been made in trapping and cooling neutral atoms. Thus the ingredients to form antihydrogen at rest are at hand. We propose to investigate the different methods to form antihydrogen at low energy, and to utilize the best of these methods to capture a number of antihydrogen atoms sufficient for spectroscopic studies in a magnetostatic trap. Once antihydrogen atoms have been captured at low energy, spectroscopic methods can be applied to interrogate their atomic structure with extremely high precision and compare it to its normal matter counterpart, the hydrogen atom. Especially the 1S-2S transition, with a lifetime of the excited state of 122 ms and thereby a natural linewidth of 5 parts in 10 16, offers in principle the possibility to directly compare matter and antimatter properties at a level of 1 part in 10 18. Additionally, comparison of the gravitational masses of hydrogen and antihydrogen, using either ballistic or spectroscopic methods, can provide direct experimental tests of the Weak Equivalence Principle for antimatter at a high precision.

Abstract

Several interferometers devoted to the detection of gravitational waves are currently being built in Europe and in the USA. The detection of the tiny mirror displacements (10−18–10−19 m) induced by a gravitational wave requires to measure fringe variations between 10−10 and 10−11 fringes. The solutions adopted for the VIRGO interferometer are described.

Abstract

Considerable evidence has been accumulating in favor of a possible involvement of viral agents in the pathogenesis of human lymphomas. The most recent proposal for a lymphoma classification, the Revised European-American Classification, emphasized for the first time the pathogenetic importance of two viruses, namely Epstein-Barr virus (EBV) and human T lymphotropic virus I (HTLV-I) in the development of certain lymphoid neoplasias. However, in the last ten years new viral agents possibly related to lymphoproliferative activity have been discovered: three herpesviruses [human herpesvirus-6 (HHV-6), -7 (HHV-7) and -8 (HHV-8)] and a flavivirus, HCV. HHV-6 was isolated from the peripheral blood of patients with lymphomas and a possible role for this beta-herpesvirus in Hodgkin's disease and in angioimmunoblastic lymphadenopathy (AILD) has emerged from serological and molecular studies. HHV-7, a beta-herpesvirus genetically close to HHV-6, has not yet been found in a human disease but it utilizes CD4 as a receptor on the lymphocyte surface. Only partial HHV-8 genomic sequences have been identified so far, suggesting a genetic homology with members of the gamma-herpesvirus family, including EBV. HHV-8 sequences have been identified for the first time in all forms of Kaposi's sarcoma as well as in a variety of lymphoid disorders, including body-cavity-based non Hodgkin's lymphomas, Castleman's disease, AILD and a type of HIV-negative reactive lymphadenopathy with peculiar histologic features. Finally, after its identification as the major cause of post-transfusion and sporadic non-A, non-B hepatitis, HCV has revealed a lymphotropism both in vitro and in vivo. A strong association between HCV infection and a benign lymphoproliferative disease, essential mixed cryoglobulinemia type II, has clearly emerged both from serological and molecular studies. A possible role for this viral infection in B-cell non Hodgkin's lymphomas not associated with cryoglobulinemia has also been proposed recently. The present work offers an overview of the huge amount of experimental and clinical observations supporting the possible involvement of these new lymphotropic viruses in human lymphoproliferative diseases.

Abstract

Hepatitis C virus (HCV) is both hepatotropic and lymphotropic and a clear-cut association has been proposed between HCV infection and mixed cryoglobulinemia (MC), a benign lymphoproliferative disorder, which sometimes evolves into a frank malignant B cell non-Hodgkin's lymphoma (B-NHL). Moreover, in the presence of antibodies to HCV, as well as of HCV-specific genomes has been reported in the sera of over 37% patients with B-NHL, not associated with MC. Thus, we decided to perform both a serologic and a molecular study to give insights into a possible relationship between HCV infection and neoplastic lymphoproliferations. We used ELISA and RIBA tests to show that anti-HCV antibodies were present in the serum of 29 out of 69 unselected B-NHL patients (42%), while seropositivity in a healthy population was about 1%. The prevalence of anti-HCV antibodies was low in definite subsets of B lymphoid disorders, including multiple myeloma, Waldenström's macroglobulinemia and monoclonal gammopathies of undetermined significance. Then, using reverse transcriptase polymerase chain reaction, we detected HCV sequences directly in the pathologic lymph node biopsies in 13 out of 34 B-NHL cases, and in particular in six out of eight low-grade lymphomas of MALT type and in five out of eight centroblastic-centrocytic follicular lymphomas. In contrast, the peripheral blood samples from 10 B cell chronic lymphocytic leukemia patients resulted negative for the presence of HCV genomes. Similarly, viral sequences were absent in 10 T cell NHL, while only one out of the 14 Hodgkin's disease cases tested resulted positive. Finally, we used a PCR-based assay to characterize the genotypes (I-IV) present in the positive lymphomatous tissues. The presence of both serologic and molecular markers of HCV infection in a high percentage of certain types of B-NHL, not associated with cryoglobulinemia, and its absence from other lymphoproliferative diseases extends the spectrum of HCV-associated lymphoproliferations arguing in favor of some role of this viral infection in the pathogenesis of the malignant proliferation of definite B lymphoid populations.

Abstract

The masses used by the Virgo interferometer to detect gravitational waves need adequate isolation from seismic noise. A multistage suspension system has been designed to extend the interferometer sensitivity down around 4 Hz. Motivations for this choice and an outline of the solutions adopted are given.
