| A Lexicon of HIV-RNA Interactions |
| | Alice Telesnitsky, University of Michigan |
|
| |
| |
Alice Telesnitsky of the University of Michigan in the U.S. seeks to define and characterize HIV interactions with host RNA. The team will attempt to determine whether disrupting or mimicking essential interactions with host RNAs may lead to antiviral strategies to which HIV cannot readily develop resistance. |
| A Novel Bactericidal Protein Found in Milk |
| | Anders Hakansson, University of Buffalo |
|
| |
| |
Anders Hakansson of the University of Buffalo in the U.S. has identified a protein from human breast milk (Human Alpha Lactalbumin Made Lethal to Tumor cell, or HAMLET), that kills respiratory tract bacteria. Hakansson will attempt to understand the mechanism by which HAMLET binds to and kills pheumococci without the bacteria developing resistance. |
| A Novel Way of Targeting TB using Aptamers and Nanotechnology |
| | Boitumelo Semete, Council for Scientific and Industrial Research (CSIR) |
|
| |
| |
To optimize the effectiveness of current anti-tuberculosis drugs, Boitumelo Semete of the CSIR in South Africa will work with collaborators to develop “sticky nanoparticles” that specifically attach to TB-infected cells. Once taken in by these cells, the nanoparticles will slowly degrade, releasing the anti-TB drugs and killing the bacteria. With this novel drug delivery system, the team aims to improve the bioavailability of the current therapies, with the possibility of shortening the treatment period for TB as well as reduce drug side effects. |
| Anti-TB Drugs That Limit Evolution of Resistance |
| | Gerald Smith, Fred Hutchinson Cancer Research Center |
|
| |
| |
Gerald R. Smith of the Fred Hutchinson Cancer Research Center in the U.S. seeks to identify inhibitors of a bacterial DNA repair enzyme that allows tuberculosis to mutate. Identifying these inhibitors could lead to therapies that kill bacteria and limit drug resistance. |
| Biosynthetic Immunotargeting for Pneumococcal Treatment |
| | David Spiegel, Yale University |
|
| |
| |
David A. Spiegel of Yale University in the U.S. will pursue an antibiotic strategy called “biosynthetic immunotargeting.” Streptococcus pneumoniae will be fed small molecules which they will incorporate into their cell walls. These small molecules contain an epitope recognized by antibodies in the human bloodstream, leading to immune clearance independent of bacterial antigens, representing a unique, resistance-free approach to pneumococcal disease. |
| Combating Antibiotic Resistance in Tuberculosis |
| | Krishna Kodukula, SRI International |
|
| |
| |
To test the theory that certain metabolic pathways essential to the survival of bacteria are immutable and therefore promising targets of drug therapy, Krishna Kodukula and colleagues at SRI International in the U.S. will identify peptides that bind key metabolites of M. tuberculosis, and test their ability to kill the bacteria. |
| Drug-Induced Differentiation of Trypanosomes Leads to Lysis |
| | Reto Brun, Swiss Tropical Institute |
|
| |
| |
Reto Brun (Swiss Tropical Institute) and Isabel Roditi (University of Bern) seek to identify the molecules that cue African trypanosomes, which are parasites that cause fatal sleeping sickness, to differentiate into the life stages necessary for transmission of the parasite. Knowing how to force this transformation prematurely within the mammalian host will allow new ways to kill trypanosomes. |
| Dual-Mode Binding Inhibitors to Suppress P. falciparum DHFRs |
| | Bongkoch Tarnchompoo, National Center for Genetic Engineering and Biotechnology |
|
| |
| |
Bongkoch Tarnchompoo of the National Center for Genetic Engineering and Biotechnology in Thailand will attempt to develop and test a novel drug that binds to the two pathways used by the DHFR enzyme in P. falciparum to mutate. By tethering these active sites, the dual-binding drug will suppress the development of resistance to anti-malarial drugs. |
| Host Targets in Mtb Infection |
| | Nigel Savage, Leiden University Medical Center |
|
| |
| |
Because tuberculosis manipulates host cells to resist the immune response and current drug therapies, Nigel Savage of Leiden University Medical Center in the Netherlands will utilize RNAi analysis to identify the essential pathways used by the bacteria to modify its host cell. By discovering these pathways, novel therapies can be developed to counteract this host manipulation without directly targeting the pathogen and causing the development of resistance. |
| Killing T. brucei by RNA Aptamer-Mediated Immobilization |
| | Arthur Günzl, University of Connecticut Health Center |
|
| |
| |
T. brucei, the parasite that causes sleeping sickness, must continuously swim forward in human blood to evade immune responses. Arthur Günzl of the University of Connecticut Health Center in the U.S. will attempt to develop serum-stable RNA molecules to immobilize the parasite by interrupting the mechanism driving parasite motility. |
