This year, I was honored to be asked to run a ‘Women In Malaria Research’ workshop alongside Dr Elena Gómez-Díaz at EMBL Heidelberg (Germany) for the 15th annual Biology and Pathology of the Malaria Parasite (‘BioMalPar’) conference. Each year at the European Molecular Biology Laboratory (EMBL)’s Heidelberg campus, approximately 200–300 scientific researchers come together to share their new data and discoveries regarding parasites of the Plasmodium genus, i.e., the parasite species (plural) that cause malaria in humans. Of course, this trip also gave me the perfect opportunity to live-tweet the entire event to those who couldn’t make it, and to provide a summary of the conference highlights here!
This year’s BioMalPar conference (28–30 May 2019) covered 3 days and was split into seven scientific sessions, with four optional workshops also included during the first 2 days. The scientific sessions were split as follows:
- Day 1: Scientific session one: Vector biology and transmission
Scientific session two: BIG data and new tools
- Day 2: Scientific session three: Development and differentiation
Scientific session four: Drug development and resistance
Scientific session five: Immunology and vaccine development
- Day 3: Scientific session six: Cell and molecular biology
Scientific session seven: Host–parasite interaction
Although the workshops and poster sessions were also jam-packed with new data, novel ideas, and potential breakthroughs, I will focus on the main talks in this summary for the sake of brevity.
The 15th BioMalPar conference was opened by a keynote lecture from Harvard’s Flaminia Catteruccia (MA, USA), who began the ‘Vector biology and transmission’ session by asserting that vector control is the best way to tackle malaria transmission. In her talk, Prof Catteruccia discussed recent findings from her lab that determined the relationship between the steroid hormone, 20-hydroxyecdysone (20E) (involved in Anopheles egg development), and the development of P. falciparum sexual stages within the mosquito midgut. Not only did she discuss these biological findings that suggest that the P. falciparum parasite has evolved a non-competitive evolutionary strategy to exploit nutrients from its female mosquito host; but she then followed this with an explanation of her game-changing paper from February that showed that Anopheles gambiae mosquitoes, when exposed to the antimalarial atovaquone upon infection, cannot transmit P. falciparum. If this landmark finding holds true, then impregnating long-lasting insecticide-treated bed nets (LLINs) with an antimalarial drug such as atovaquone could prevent the spread of malaria by targeting the mosquito.
Prof Catteruccia’s keynote lecture was followed by three more impressive vector-focused talks from Dr Rikita Bishnoi (Temple University, PA, USA), Dr Elena Gómez-Díaz (IPBLN-CSIC, Granada, Spain), and Prof Justin Boddey (Walter and Eliza Hall Institute of Medical Research (WEHI), Melbourne, Australia); all describing different facets of Anopheles mosquito biology, from the specificities of the mosquito immune response (Dr Bishnoi), through regulation of the mosquito genome (Dr Gómez-Díaz), to parasite molecular mechanisms that drive mosquito transmission (protein glycosylation) (Prof Boddey). And for those unaware, Prof Boddey is presently an organizer for the upcoming ‘Molecular Approaches to Malaria’ (MAM) 2020 conference. He also dropped a few hints about upcoming publications from his lab; so keep an eye out for “Jennison et al.” and “Lopaticki et al.” coming out of the Walter and Eliza Hall Institute!
In the afternoon, the discussion moved to ‘BIG data and new tools’ in malaria research. This session began with a keynote lecture by eminent Plasmodium bioinformatician, Dr Thomas Otto (Wellcome Centre for Integrative Parasitology (WCIP), Glasgow, UK), on the progression (and limitations) of the canonical P. falciparum reference genome. Three more ‘BIG data’ talks followed Dr Otto’s impressive introduction. Dr Sudhir Kumar (Seattle Children’s Research Institute, WA, USA) discussed the identification of genetic loci associated with parasite fitness using experimental genetic crosses between P. falciparum lines and bulk segregant analysis of resultant whole genomes. Prof Peter Preiser (Nanyang Technological University, Singapore) and Richard Thomson Luque (Heidelberg University) wrapped up the ‘BIG data’ session with large-scale proteomics and transcriptomics; with Richard Thomson Luque’s work from the lab of Dr Silvia Portugal to be published in future.
Some intriguing ‘New tools’ for Plasmodium research marked the end of session two. Both talks, from Mélanie Pellisson of the Swiss Tropical and Public Health Institute (Geneva, Switzerland), and Dr Alena Pance of the Wellcome Sanger Institute (Cambridge, UK), discussed the development of stem cell-based strategies to tackle long-held questions in malaria research. Mélanie Pellisson showed novel data from her work in characterizing monkey iPS-derived hepatocytes, and their potential as a tool to study P. cynomolgi hypnozoite development in vitro. In Dr Alena Pance’s case, host-derived stem cells provide a novel avenue by which the host immune response to a Plasmodium infection can be studied, with Dr Pance even discussing iPS cells reprogrammed from alpha thalassemia patients! Both of these final talks were unpublished and I am sure that I wasn’t the only person in the conference room looking forward to seeing these results when they finally come out!
As is tradition, day one of BioMalPar ended with the presentation of a Lifetime Achievement Award; each year granted to a scientist whose research has substantially impacted or changed the face of malaria research. Past winners include Hagai Ginsburg, Victor and Ruth Nussenzweig, and Richard Carter; all giants in the Plasmodium field. This year’s winner was a pioneer in the study of both antigenic variation and genomics in the malaria parasite: Prof Chris Newbold (University of Oxford, UK). This year’s BioMalPar attendants were treated to a video presentation by Oxford’s Prof Kevin Marsh, who gave a timeline of Prof Newbold’s work, firstly at the National Institute of Medical Research (NIMR) at Mill Hill in London (UK), and later to become the University of Oxford’s Head of Molecular Parasitology, helping to establish the KEMRI-Wellcome Trust Research Programme in Kenya along the way. Prof Newbold was a key figure in the generation of the Plasmodium falciparum genome sequence, as Prof Marsh said, bringing together a “Bioinformatics Dream Team” that included both Dr Thomas Otto and Dr Ulrike Böhme from the Wellcome Sanger Institute (who still continue to curate, annotate, and improve the Plasmodium genome sequences at PlasmoDB!). Prior to a talk by Prof Newbold himself about his lab’s current work in the investigation of multi-gene families that contribute to pathogenesis in Plasmodium infections, a quote was provided by Prof Marsh from a past member of Prof Newbold’s lab. This quote, and a link to a webpage about Chris Newbold’s continued work in malaria, are provided below.
A resounding round of applause followed Prof Chris Newbold’s Lifetime Achievement Award lecture, in which he discussed his continued work in determining how multi-gene families (such as the Plasmodium var and pir gene families) mediate parasite virulence, and how the human immune response is elicited upon variation in the resultant parasite proteins and epitopes. A link to publications from the Newbold Lab is provided below.
Day two of BioMalPar 2019 started with a scientific session on ’Development and differentiation’. This session focused on the sexual development of the Plasmodium parasite in the human host before transmission to a mosquito, i.e., gametocytogenesis. The production of Plasmodium gametocytes is a potentially targetable bottleneck in Plasmodium life-cycle progression. A leader in this field, Prof Matt Marti of WCIP, opened this session with a comprehensive discussion of his lab’s work. Prof Marti’s group has provided insights into the localization (or ‘sequestration’) of Plasmodium gametocytes in human bone marrow red blood cell precursors and the spleen; the role of the host-derived lipid lysophosphatidylcholine (LysoPC) in differentiation of asexual parasites to gametocytes; and the naturally acquired host immune response to gametocytes. Prof Marti’s talk was followed by four more talks that focused on specific molecular mechanisms or factors that demonstrated a role in gametocyte differentiation (look out for a future paper on a Plasmodium “protein acting as a parasite load regulator (PARLOR)” from Alexander Maier of the Australian National University (ANU) and work from Kirchner et al. at the Wellcome Centre in Glasgow!).
Scientific sessions five and six of BioMalPar 2019 centered around attempts to target the parasite with either drugs (session five) or vaccines (session six), alongside explanations of the parasites’ corresponding attempts to thwart these efforts. Prof Leann Tilley of the University of Melbourne awed the crowd with the newly published crystal structure of the P. falciparum PA28-20S proteasome complex, part of her lab’s work to target parasite proteostasis for antimalarial production. Recent work from Catherine Lavazec, Dina Coertzen, and Anja Schlott followed this keynote lecture, with Sabine Schmidt of the Bernhard Nocht Institute for Tropical Medicine (BNITM; Hamburg, Germany) showing some as-yet-unpublished work regarding the Kelch13-mediated mechanisms of malaria resistance to artemisinin (so keep an eye out for this research in future!).
Beginning the ‘Immunology and vaccine development’ session was Prof Eleanor Riley, current Director of the Roslin Institute at the University of Edinburgh (UK). Prof Riley provided an enlightening talk that addressed both the human immune response to infection with Plasmodium (with a particular focus on the neutrophil response), and the phenomenon of asymptomatic (subpatent) P. falciparum infections. A link to a recent publication regarding the temporal dynamics and infectiousness of these subpatent infections from the Riley Lab is provided below. The final four talks of this session provided insights into B-cell subset and antibody responses to Plasmodium infection. Timon Damelang, a PhD student in the lab of Prof Stephen Kent at the University of Melbourne, gave the crowd a taster of his yet-to-be-published research into functional antibodies in the protection of pregnant women from malaria. So, more to come from this lab!
The final day of BioMalPar 2019 began with a session of “Cell and molecular biology”, with the first keynote lecture of the day provided by Prof Wai-Hong Tham of WEHI in Australia. Prof Tham gave the first full-length talk regarding P. vivax, discussing her work in characterizing the P. vivax-specific invasion complex formed by P. vivax reticulocyte-binding protein 2b (PvRBP2b) and the human transferrin receptor 1 (TfR1). Prof Tham discussed the potential of these discoveries in informing future P. vivax vaccine candidates and alluded to further work regarding the binding and invasion mechanisms of P. vivax. From this P. vivax work followed six more talks regarding cell and molecular biology findings, largely in P. falciparum. Elisabet Tintó of the Cortés Lab at ISGlobal in Spain introduced a new member of the AP2 transcription factor family by showing some of her unpublished research into AP2-HS, a heat shock response protein in Plasmodium parasites. Publications discussed during talks by Dr Sujaan Das (Ludwig-Maximilians-University, Munich, Germany), Dr Edgar Deu (Francis Crick Institute, London, UK), Dr Yuneun Avalos Padilla (Max Plank Institute, Germany), Prof Rita Tewari (University of Nottingham, UK), and Dr Konstantinos Kousis (Francis Crick Institute) are listed below.
For the final BioMalPar 2019 scientific session entitled “Host–pathogen interactions”, Prof Stefan Kappe of the University of Washington (WA, USA) discusses the study of the pre-erythrocytic stages of the malaria parasite, namely, the sporozoite and exo-erythrocytic forms (EEFs) in the host liver. Prof Kappe champions the development of whole sporozoite vaccines, particularly the production of genetically attenuated, replication-competent vaccine strains that, experimentally, appear to elicit superior immunity to malaria infection. By targeting the parasite stages prior to replication within host red blood cells, Prof Kappe aims to arrest the Plasmodium lifecycle before a symptomatic disease develops. In a similar vein, Dr Gavin Wright of the Wellcome Sanger Institute followed with a talk detailing another potential vaccine candidate: targeting the (species-specific) Plasmodium Reticulocyte-binding protein Homolog 5 (RH5) which attaches to the host red blood cell basigin glycoprotein, facilitating parasite invasion into the cell. Again, preventing this interaction from occurring would stop the parasite from progressing to a symptomatic intra-erythrocytic infection. Together, these two talks provided a fascinating insight into ongoing studies of two promising malaria vaccine candidates.
Wrapping up the conference were three talks about novel, mostly unpublished, research describing the role of host microbiota in Plasmodium parasite growth and development (Debanjan Mukherjee of the Mota Lab, Instituto de Medicina Molecular, Lisbon, Portugal); var gene expression in malaria-naïve patients infected with two separate P. falciparum strains (Jan Stephan Wichers of the Gilberger Lab at BNITM); and new tools for genome editing in P. knowlesi (presented by Melissa Hart of the Moon Lab at the London School of Hygiene and Tropical Medicine (LSHTM; UK)). It will be exciting to see the publication of many of these results at future BioMalPar conferences!
To end our EMBL Heidelberg trip with more food for thought, Prof Gary Ward of the University of Vermont (VT, USA) delivered a final plenary session regarding academic publishing and the road to open access journals in science. Though I am staunchly in favor of open access publishing, I learned a lot more about the movement within academia from Prof Ward at BioMalPar 2019. For everyone’s reference, I have included a link to the ‘Plan S’ open access initiative below, something that I was unaware of before this conference. I have also included a link to the ‘Declaration on Research Assessment (DORA)’ website, a list of recommendations about how the output from scientific research across different fields should be assessed by funding agencies, universities, among others. This final session assured that, at the end of BioMalPar 2019, I left Heidelberg with much more knowledge about my chosen field of research than I had arrived with.
Though much longer than I intended (sounds just like my PhD thesis!), this summary only touches on the wealth of outstanding research into malaria that is currently being carried out worldwide, and doesn’t do justice to the dozens of fantastic posters that were also presented this year. If you want to be a part of next year’s BioMalPar at EMBL Heidelberg, the abstract deadline is February 2020!
