Staying ahead of SARS-CoV-2
EvaMobs at the Microbiology Society Annual Conference 2026
Recently, Marta Alenquer, scientist at Católica Biomedical Research Centre and one of our EvaMobs team members, represented the project at the Microbiology Society Annual Conference 2026, sharing new insights into the development of antiviral strategies against SARS-CoV-2 and beyond.
Advancing antiviral research against SARS-CoV-2
At the conference, she presented a poster highlighting her work on novel antiviral molecules designed to block SARS-CoV-2. Marta explains: “I presented a poster with results from in vitro neutralisation assays evaluating computationally designed miniproteins targeting the SARS-CoV-2 spike protein.”
These miniproteins are small, engineered molecules designed to attach to the virus’s spike protein – the structure used to enter human cells. To safely test how well these candidates work, Marta and her team use so-called lentiviral spike-pseudotyped particles, which are harmless virus-like particles that mimic how SARS-CoV-2 infects cells. This allows researchers to measure antiviral activity in a controlled laboratory setting.
Using this approach, Marta and her team assessed a panel of candidate molecules. “We identified four candidates with strong neutralising capacity, including one with particularly high potency,” Marta mentioned. Her research also explored ways to further improve the effectiveness of these molecules. “I also showed how multivalent can substantially enhance neutralisation efficiency.” By designing proteins that contain multiple binding domains (multivalent), their ability to prevent the SARS-CoV-2 virus from infecting cells increased.
Exchanging knowledge and gaining new perspectives
The conference provided an excellent opportunity to exchange ideas with researchers working on related antiviral and host–virus interaction topics. Marta mentioned: “I particularly valued the discussions on emerging approaches to tackle viral evolution and resistance, as well as the opportunity to present my work and receive constructive feedback from the community.”
Strengthening the EvaMobs pipeline
Marta’s contribution to the EvaMobs project focuses on the experimental validation of antiviral candidates, which is a key component of the EvaMobs pipeline. Marta explains: “By establishing and applying robust neutralisation assays, this work enables the functional assessment of designed molecules and supports the identification of the most promising candidates for further optimisation.” This directly contributes to EvaMobs’ goal: accelerating the development of effective antiviral strategies against emerging viruses.
