Assessing the prevalence of neutralizing antibodies (NAbs) to SARS-CoV-2 during three years of the COVID-19 pandemic.

The development of COVID-19 vaccines has been an important step in the fight against the pandemic. However, it is still necessary to understand the influence of factors that can alter the immune response. In general, doses need to be updated frequently, and care must be taken to control the virus that is still circulating worldwide.

Ongoing replication stress tolerance and clonal T cell responses distinguish liver and lung recurrence and outcomes in pancreatic cancer.

Patients with metastatic pancreatic ductal adenocarcinoma survive longer if disease spreads to the lung but not the liver. Here we generated overlapping, multi-omic datasets to identify molecular and cellular features that distinguish patients whose disease develops liver metastasis (liver cohort) from those whose disease develops lung metastasis without liver metastases (lung cohort). Lung cohort patients survived longer than liver cohort patients, despite sharing the same tumor subtype.

Engineering Protein Dynamics through Mutational Energy Landscape Traps.

Protein dynamics is essential for various biological processes, influencing functions such as enzyme activity, molecular recognition, and signal transduction. However, traditional protein engineering methods often focus on static structures, lacking tools to precisely manipulate dynamic behaviors. Here, we developed Mutational Energy Landscape Trap (MELT), a novel method designed to control protein dynamics by combining Normal Mode Analysis (NMA) and mutagenesis.
