How COVID-19 has changed medical research funding.

Here, we consider how the lessons we learned in 2020 from funding COVID-19 research could have a long-term impact on the way that we fund medical research. We look back at how UK government funding for COVID-19 medical research evolved, beginning with the early calls for proposals in February that pump-primed funding for vaccines and therapeutics, and culminating in the launch of the government's National Core Studies programme in October. We discuss how the research community mobilized to submit and review grants more rapidly than ever before, against a background of laboratory and office closures.

UK vaccines network: Mapping priority pathogens of epidemic potential and vaccine pipeline developments.

During the 2013-2016 Ebola outbreak in West Africa an expert panel was established on the instructions of the UK Prime Minister to identify priority pathogens for outbreak diseases that had the potential to cause future epidemics. A total of 13 priority pathogens were identified, which led to the prioritisation of spending in emerging diseases vaccine research and development from the UK. This meeting report summarises the process used to develop the UK pathogen priority list, compares it to lists generated by other organisations (World Health Organisation, National Institutes of Allergy and Infectious Diseases) and summarises clinical progress towards the development of vaccines against priority diseases.

Predictors for Using a HIV Self-Test Among Migrant and Seasonal Farmworkers in North Carolina.

Background: Approximately, two million migrant and seasonal farmworkers (MSF) work in the United States annually. Several factors, such as lack of access to healthcare services and health behaviors, contribute to risk of HIV transmission. Relatively few studies have explored MSF knowledge of HIV transmission and testing options.

Plasma biomarkers of brain atrophy in Alzheimer's disease.

Peripheral biomarkers of Alzheimer's disease (AD) reflecting early neuropathological change are critical to the development of treatments for this condition. The most widely used indicator of AD pathology in life at present is neuroimaging evidence of brain atrophy. We therefore performed a proteomic analysis of plasma to derive biomarkers associated with brain atrophy in AD.

Plasma transthyretin as a candidate marker for Alzheimer's disease.

Diagnosis of the progressive neurodegenerative disorder Alzheimer's disease (AD) can only definitively be made postmortem. The most promising AD biomarkers identified to date are found in cerebrospinal fluid (CSF). Among these, one of the most interesting candidates is transthyretin (TTR), the carrier of thyroxine and retinol, which also binds with amyloid-β (Aβ), and it has been suggested that it protects against Aβ deposition.

Plasma clusterin concentration is associated with longitudinal brain atrophy in mild cognitive impairment.

Recent genetic and proteomic studies demonstrate that clusterin/apolipoprotein-J is associated with risk, pathology, and progression of Alzheimer's disease (AD). Our main aim was to examine associations between plasma clusterin concentration and longitudinal changes in brain volume in normal aging and mild cognitive impairment (MCI). A secondary objective was to examine associations between peripheral concentration of clusterin and its concentration in the brain within regions that undergo neuropathological changes in AD.

Proteome-based plasma markers of brain amyloid-β deposition in non-demented older individuals.

Blood-based markers reflecting core pathological features of Alzheimer's disease (AD) in pre-symptomatic individuals are likely to accelerate the development of disease-modifying treatments. Our aim was to discover plasma proteins associated with brain amyloid-β (Aβ) burden in non-demented older individuals. We performed discovery-phase experiments using two dimensional gel electrophoresis (2DGE) and mass spectrometry-based proteomic analysis of plasma in combination with 11C-PiB PET imaging of the brain in samples collected 10 years prior to the PET scans.

Protease activated receptors 1 and 4 sensitize TRPV1 in nociceptive neurones.

Protease-activated receptors (PAR1-4) are activated by proteases released by cell damage or blood clotting, and are known to be involved in promoting pain and hyperalgesia. Previous studies have shown that PAR2 receptors enhance activation of TRPV1 but the role of other PARs is less clear. In this paper we investigate the expression and function of the PAR1, 3 and 4 thrombin-activated receptors in sensory neurones.

Association of plasma clusterin concentration with severity, pathology, and progression in Alzheimer disease.

Context: Blood-based analytes may be indicators of pathological processes in Alzheimer disease (AD).

Objective: To identify plasma proteins associated with AD pathology using a combined proteomic and neuroimaging approach.

Design: Discovery-phase proteomics to identify plasma proteins associated with correlates of AD pathology.

Minocycline reduces the development of abnormal tau species in models of Alzheimer's disease.

Alzheimer's disease (AD) is characterized by the presence of neurofibrillary tangles of hyperphosphorylated, aggregated tau protein and extracellular deposits of beta-amyloid peptide. Increased beta-amyloid levels are thought to precede tangle formation, but tau pathology is more closely related to neuronal death. Minocycline, a tetracycline derivative, has potent antiinflammatory, antiapoptotic, and neuroprotective effects in several models of neurodegenerative disease, including models of AD with amyloid pathology.
