Dendritic cells (DCs) are essential in order to combat invading viruses and trigger antiviral responses. Paradoxically, in the case of HIV-1, DCs might contribute to viral pathogenesis through trans-infection, a mechanism that promotes viral capture and transmission to target cells, especially after DC maturation. In this review, we highlight recent evidence identifying sialyllactose-containing gangliosides in the viral membrane and the cellular lectin Siglec-1 as critical determinants for HIV-1 capture and storage by mature DCs and for DC-mediated trans-infection of T cells. In contrast, DC-SIGN, long considered to be the main receptor for DC capture of HIV-1, plays a minor role in mature DC-mediated HIV-1 capture and trans-infection.

[EN]In this project has been developed a tool which synthesizes realistic waveforms produced by the intra-aortic balloon pump. In addition the following waveforms have also been synthesized: arterial blood pressure (ABP) waveform, the four variations produced due to timing errors of the balloon and the waveform of the helium gas rapidly shuttling in and out of the balloon chamber. All waveforms are synthesized in synchrony with the balloon's inflation/deflation cycles. A database composed of annotated ECG (Electrocardiogram) normal sinus rhythm records has also been created during the project. In order to facilitate the work, two graphical user interfaces were developed. The first interface allows the selection of the ECG records, which were latter annotated using the second interface. Starting from the newly created annotated database, the different waveforms, mentioned above, were synthesized. In this document, in view of the synthesized waveforms, it can be concluded that the obtained results are satisfactory.
