Nucleoside Hydrolase NH 36: A Vital Enzyme for the Leishmania Genus in the Development of T-Cell Epitope Cross-Protective Vaccines
Conclusions Nucleoside hydrolases are vital enzymes for the replication of Leishmania, conserved phylogenetic marker of the genus and strong-specific immunogens. We demonstrated that NH36 is an excellent target for chemotherapy of visceral leishmaniasis. Searching for the most immunogenic fraction of promastigotes of Leishmania we described the FML antigen of L. (L.) donovani, that has as its main component, the NH36 Nucleoside hydrolase. We developed second–generation vaccines with the FML and the NH36 native antigens, and with the NH36 recombinant protein. In addition, we obtained a third generation vaccine based upon the NH36 gene. All these vaccines were protective and curative when assayed in the murine and canine models of leishmaniasis, and the FML-vaccine called Leishmune® reduced the incidence of human and canine disease in the endemic areas. Recently we initiate the search for the most immunogenic part of the NH36 sequence aiming to optimize the vaccine efficacy. We observed that the F3 vaccine has an important role in signaling the optimal control of visceral leishmaniasis in mice and that the F1 domain is also needed for protection against tegumentary leishmaniasis. This knowledge allowed us to develop a recombinant chimera vaccine, which optimized the vaccine efficacy. Furthermore, aiming to develop a potential T-cell epitope synthetic vaccine against both human visceral and cutaneous leishmaniasis we identified the major immunogenic regions of NH36 re...
Authors: Reissier S, Cattoir V Abstract INTRODUCTION: Streptogramins (pristinamycin and quinupristin-dalfopristin) can be interesting options for the treatment of infections due to Gram-positive cocci, especially multidrug-resistant isolates. AREAS COVERED: This review provides an updated overview on structural and activity characteristics, mechanisms of action and resistance, pharmacokinetic/pharmacodynamic and clinical use of streptogramins. EXPERT OPINION: The streptogramin antibiotics act by inhibition of the bacterial protein synthesis. They are composed of two chemically distinct compounds, namely typ...

We describe the most highly recommended generic and disease-specific PRO tools in SCD and discuss the challenges of incorporating them in clinical practice. EXPERT OPINION: PRO measures are essential to incorporate into SCD clinical trials either as primary or secondary outcomes. The use of PRO measures in SCD facilitates a patient-centered approach, which is likely to lead to improved outcomes. Significant challenges remain in adapting PRO tools to routine clinical use and in developing countries. PMID: 33034214 [PubMed - as supplied by publisher]
Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...
