The utilization of transgenic plants expressing recombinant antigens to be used in the formulation of experimental immunogens has been recently communicated. We report here the development of transgenic plants of alfalfa expressing the structural protein VP1 of foot and mouth disease virus (FMDV). The presence of the transgenes in the plants was confirmed(More)
ATM and PARP-1 are two of the most important players in the cell's response to DNA damage. PARP-1 and ATM recognize and bound to both single and double strand DNA breaks in response to different triggers. Here we report that ATM and PARP-1 form a molecular complex in vivo in undamaged cells and this association increases after γ-irradiation. ATM is also(More)
We used the species specificity and repetitious nature of subtelomeric kinetoplastida sequences to generate a duplex PCR assay for the simultaneous detection of Trypanosoma cruzi and Trypanosoma rangeli in experimentally and naturally infected triatomine (Reduviid) bugs and in infected human subjects. The assay was species specific and was capable of(More)
Poly(ADP-ribose) polymerase-1 (PARP-1) is a nuclear protein that, once activated by genotoxic agents, modulates the activity of several nuclear proteins including itself. Previous studies have established that PARP-1 inhibition may provide benefit in the treatment of different diseases, particularly those involving a hypoxic situation, in which an increased(More)
The ability of a recombinant baculovirus containing the ectodomain of the mature sequence of glycoprotein D (gD) fused to the amino-terminus of baculoviral glycoprotein gp64 to display gD on its surface and to serve as an improved immunogen against bovine herpesvirus-1 was tested. The gD–gp64 fusion protein was correctly expressed on the virus particles as(More)
Culture filtrate and cell extracts from Mycobacterium bovis cultures contain molecules which could promote protective immunity to tuberculosis in animals. Different protein fractions of M. bovis cultures were obtained by elution electrophoresis and were tested in experimentally infected cattle. The fractions that elicited gamma interferon (IFN-gamma)(More)
We test the hypothesis that PARP inhibition can decrease acute tubular necrosis (ATN) and other renal lesions related to prolonged cold ischemia/reperfusion (IR) in kidneys preserved at 4°C in University of Wisconsin (UW) solution. Material and Methods. We used 30 male Parp1(+/+) wild-type and 15 male Parp1(0/0) knockout C57BL/6 mice. Fifteen of these(More)
