Project description:Tsetse transmit African trypanosomiasis, which is a disease fatal to both humans and animals. A vaccine to protect against this disease does not exist so transmission control relies on eliminating tsetse populations. Although neurotoxic insecticides are the gold standard for insect control, they negatively impact the environment and reduce populations of insect pollinator species. Here we present a promising, environment-friendly alternative to current insecticides that targets the insect tyrosine metabolism pathway. A bloodmeal contains high levels of tyrosine, which is toxic to haematophagous insects if it is not degraded and eliminated. RNA interference (RNAi) of either the first two enzymes in the tyrosine degradation pathway (tyrosine aminotransferase (TAT) and 4-hydroxyphenylpyruvate dioxygenase (HPPD)) was lethal to tsetse. Furthermore, nitisinone (NTBC), an FDA-approved tyrosine catabolism inhibitor, killed tsetse regardless if the drug was orally or topically applied. However, oral administration of NTBC to bumblebees did not affect their survival. Using a novel mathematical model, we show that NTBC could reduce the transmission of African trypanosomiasis in sub-Saharan Africa, thus accelerating current disease elimination programmes.

Project description:The transmission of antimicrobial resistance (AMR) between food-producing animals (poultry, cattle and pigs) during short journeys (< 8 h) and long journeys (> 8 h) directed to other farms or to the slaughterhouse lairage (directly or with intermediate stops at assembly centres or control posts, mainly transported by road) was assessed. Among the identified risk factors contributing to the probability of transmission of antimicrobial-resistant bacteria (ARB) and antimicrobial resistance genes (ARGs), the ones considered more important are the resistance status (presence of ARB/ARGs) of the animals pre-transport, increased faecal shedding, hygiene of the areas and vehicles, exposure to other animals carrying and/or shedding ARB/ARGs (especially between animals of different AMR loads and/or ARB/ARG types), exposure to contaminated lairage areas and duration of transport. There are nevertheless no data whereby differences between journeys shorter or longer than 8 h can be assessed. Strategies that would reduce the probability of AMR transmission, for all animal categories include minimising the duration of transport, proper cleaning and disinfection, appropriate transport planning, organising the transport in relation to AMR criteria (transport logistics), improving animal health and welfare and/or biosecurity immediately prior to and during transport, ensuring the thermal comfort of the animals and animal segregation. Most of the aforementioned measures have similar validity if applied at lairage, assembly centres and control posts. Data gaps relating to the risk factors and the effectiveness of mitigation measures have been identified, with consequent research needs in both the short and longer term listed. Quantification of the impact of animal transportation compared to the contribution of other stages of the food-production chain, and the interplay of duration with all risk factors on the transmission of ARB/ARGs during transport and journey breaks, were identified as urgent research needs.

Project description:Terahertz (THz) frequency occupies a large portion of the electromagnetic spectrum that is between the infrared and microwave region. Recent advances in THz application have stimulated interests regarding the biological effects associated with this frequency range. In current study, we report that irradiation with a single-frequency THz laser on primary mice cortical neuron cultures and oligodendrocyte cultures results in dose dependent irradiation specific changes in cellular function and gene expression. In neuron cultures, THz irradiation increases excitatory synaptic transmission and neuronal firing activities. Microarray assay reveals neuronal gene expression dynamics after THz exposure, which are highly consistent with morphology and electrophysiology results. Besides, certain schedule of THz irradiation inhibits the proliferation of oligodendrocyte precursor cells (OPCs) and promotes OPC differentiation. Notably, the myelination process in neuron-oligodendrocyte cocultures is enhanced after THz exposure. In summary, our observations suggest that THz irradiation in certain frequency can modulate the functions of neuron and oligodendrocyte, with different sensitivity to THz between neuronal cell types. These results may provide important understanding of the mechanisms that govern THz interactions with nervous systems and suggest THz wave as a new strategy for neuromodulation.

Project description:The aim of this study was to compare the transcriptomes of Plasmodium falciparum parasites sourced from high vs. low malaria transmission settings in east Africa in order to test the hypothesis that malaria parasites are locally adapted to their environment. In three separate experiments, parasites from ‘High’ vs. ‘Low’ transmission populations were taken from non-immune children and measured for gene expression levels by microarray against a reference genome. Two of these population comparisons were geographic in nature while the third was temporal, i.e., before and after a marked decline in malaria.
