Diseño y producción de una herramienta molecular para el estudio del N-terminal de la nicotinamida mononucleótido adenilil transferasa (NMNAT) en Leishmania braziliensis

Leishmania braziliensis is a protozoan which is cause of the most of the cutaneous leishmaniasis cases in at least 15 countries from America. World Health Organization (WHO) has reported that around 12 millions of people are infected in the world and this number increase every year. Because of the delicate problem of public health due to the prevalence of this disease, it is necessary the metabolism study in this parasite. In this way has been studied NMNAT protein of the parasite, which is a central enzyme of the metabolism of all organisms, since it is in charge of synthesizing NAD+, an important cofactor in oxidation-reduction reactions of central processes in the cellular metabolism. In The NMNAT of L. braziliensis has been found a 43 amino acids sequence in the N terminal, which does not have homology with the protein in the human host. In this study were produced IgG antibodies against this sequence, using like antigens peptides that had the mentioned sequence. The produced antibodies recognized the recombinant NMNAT of L. braziliensis through western blot assay.
