Cambridge-Chennai Centre Partnership on Antimicrobial Resistant Tuberculosis

Lead Research Organisation: University of Cambridge
Department Name: Medicine

Abstract

The need for a joint India-UK Centre Partnership focused on drug-resistant tuberculosis (TB) is founded on the scale of the problem both in India and globally, combined with the pressing need to develop new tools and therapeutics to combat it. There were 1,467,585 cases of TB notified in India during 2012 (the largest number of cases in any country worldwide), with a sharp rise in the number of people diagnosed with multidrug resistant (MDR) TB (from 308 to 16,588 laboratory confirmed cases between 2008 and 2012). Our partnership between the University of Cambridge and the National Institute for Research in Tuberculosis (NIRT) in Chennai, India, will bring together a multidisciplinary team to focus on novel diagnostics and therapeutics for TB. This includes the use of emerging sequence-based diagnostics to improve the accuracy of individual patient treatment for MDR and extensively drug resistant (XDR) TB; new drug targets for TB and prediction/investigation of the impact of resistance mutations based on modelling of bacterial genome data; the development of an in-depth understanding of the bacterial genes in diverse populations of Mycobacterium tuberculosis associated with so-called 'drug tolerance'; and novel approaches to treatment of TB based on immunomodulation (enhancement of autophagy and novel enhancers of T cell responsiveness). The Centre Partnership will generate a rich and lasting clinical and genomic dataset. Our objectives require detailed clinical and biological phenotyping and genotyping of patient cohorts, which can be mined to address future questions and will further enhance collaborative research to tackle the burden of drug-resistant TB. We will also innovate in training and knowledge transfer. Leveraging of novel technologies will increase relevant and collaborative research experience for UK and Indian investigators. Transfer of scientific training and technology to India enhances independent research capacity and fosters future international collaborative projects. This will be achieved through mobility and exchange of junior (training) and senior (discipline-hopping) researchers.

Description Our aim was to build on an existing programme of collaborative research on multidrug-resistant and extensively drug-resistant (MDR- and XDR-) tuberculosis (TB). The two nodes (the National Institute for Research in Tuberculosis (NIRT), Chennai, and the University of Cambridge) have highly complementary skills that encompass epidemiology, human and pathogen genetics, immunology, cellular and molecular biology, diagnostic microbiology, drug discovery, and clinical trials experience, together with access to extensive patient populations and isolate collections. This multidisciplinary combination has been used through an effective partnership to develop a holistic approach to new diagnostics, treatment algorithms, and therapeutic approaches for drug-resistant TB. Novel mechanisms of antimicrobial drug resistance in M. tuberculosis have been explored using cutting edge techniques and correlated with clinical outcomes.
Exploitation Route TB sequencing was established at the National TB reference laboratory.
Sectors Healthcare

 
Description Establish sustainable knowledge transfer by establishing sequencing as a research tool in Chennai. The introduction of an Illumina MiSeq instrument in Chennai as part of this Partnership was successful in transferring capabilities, knowledge and training. The teams in Cambridge and NIRT worked closely together to set up the Illumina MiSeq machine, supported by training in library preparation to achieve optimum performance. Narender Kumar built in-house bioinformatics analysis capacity with a workstation that was configured with all the necessary tools/software installed. In addition, the sequencer, the workstation and the storage place were configured to enable automated data transfer capability. A custom bioinformatics analysis pipeline was designed and implemented at NIRT to process the raw fastq files generated from the sequencer which involved filtering, mapping to H37Rv reference, variant calling. The variants identified were then compared against the local database of mutations to predict resistance. The pipeline has been installed locally and two of the staff members has been trained to run the analysis independently. A basic bioinformatics training was also provided by Narender Kumar to ~10 local staff in batches of 5 at NIRT. The training involved a week-long course including both theoretical and practical sessions. The participants were taught basics of using command line system (Linux/Unix), understanding and assessing the sequence data quality generated from the sequencer, filtering, mapping and father analysis of the sequence data. In addition, information and usage of various publicly available tools were shared for the analysis of the data. Narender Kumar attended a summer school on TB research methods held at McGill Summer Institute in Infectious Diseases and Global Health in Montreal, Canada between 11th to 16th June, 2018.

Description TEDDY consortium collaboration 
Organisation The Environmental Determinants of Diabetes in the Young consortium
Sector Charity/Non Profit 
PI Contribution I have analysed data generated by the TEDDY consortium with a manuscript written and currently under review at Nature. The consortium has provided biosamples from its repository that we have processed to generate new pilot data and we have used that data to apply (to the consortium) for additional funding as indicated to generate more detailed data. We analysed longitudinal blood transcriptomes of 2013 samples from 401 individuals, covering two nested case:control studies of T1D and islet autoimmunity (IA) respectively. We describe extensive gene expression changes in healthy infancy, common to both cases and controls, but also changes correlating with progression to T1D. Distinct changes in gene expression are apparent in patient subgroups defined by their sequence of autoantibody seroconversion. Initial development of insulin autoantibodies (IAA) is associated with an increasing natural killer cell signature, not seen in those initially developing GAD65 reactive islet antibodies (GADA).
Collaborator Contribution The TEDDY consortium is a prospective cohort study aiming to determine genetic and environmental interactions causing T1D. TEDDY has compiled an extensive, prospective biosample collection from children at risk of T1D. They have provided both samples and funding to facilitate our collaboration.
Impact 1. Manuscript submitted describing analysis of longitudinal transcriptomes in children at risk of T1D (under review at Nature) 2. Single cell pilot data generated using samples from the TEDDY repository, indicating the feasibility of undertaking single cell transcriptomic analysis of serial samples from children at risk of T1D.

Title mCSM 
Description Machine learning approach to predicting the impacts of mutations on protein stability and interactions with other proteins, nucleic acids, and small molecule ligands.

Title sdm 
Description An updated webserver for the improved SDM, used for predicting the effects of mutations on protein stability. We have updated the environment-specific amino-acid substitution tables based on the current expanded PDB (a 5 fold increases in information), and introduced new residue conformations and interaction parameters, including packing density and residue depth. 
Type Of Technology Webtool/Application 
Year Produced 2017 
Impact The updated server has been extensively tested using a wide benchmark containing 2690 point mutations from 132 different protein structures. Using an established benchmark, the revised method correlated well against the hypothetical reverse mutations, better than comparable methods built using machine-learning approaches, highlighting the strength of our knowledge-based approach for identifying stabilising mutations. Given a PDB file (a Protein Data Bank file format containing the three-dimensional coordinates of the protein atoms), and a point mutation, the server calculates the stability difference score between the wildtype and mutant protein.
