In this Tools of the Trade article, Giulia Adriani and Andrea Pavesi describe a new microfluidic device that supports the generation of vascularized 3D tumour models.
In this Tools of the Trade article, Zülal Cibir and Matthias Gunzer introduce their multi-lens array microscope called ComplexEye that allows high-throughput analysis of cell migration.
Investigation of neutrophil heterogeneity in tumours reveals the irreversible programming of long-lived, pro-angiogenic neutrophils that drive tumour progression.
A preprint by Kim et al. shows that the brain parenchyma can be seeded with age with clonal haematopoiesis-derived monocytes that drive neuropathology.
While anticipating the development of a COVID-19-specific vaccine, several randomized controlled trials (RCTs) explored the potential of BCG vaccination to protect against COVID-19, based on trials demonstrating beneficial effects of BCG vaccination on unrelated infections and all-cause mortality in neonates in high-mortality geographical settings. Results are now available from 12 RCTs, which suggest that BCG vaccination is not an effective intervention against COVID-19. That the BCG–COVID-19 trials failed to meet expectation emphasizes the importance of rigorous clinical trials to validate hypotheses, even in urgent situations such as a pandemic.
A preprint by Kwok et al. describes the identification of common neojunction-derived antigens that could serve as targets for ‘off the shelf’ vaccines or adoptive cell therapies for patients with various types of cancer.
The failure of T cell-targeted vaccines for HIV in clinical trials is likely due to impaired degranulation of low-avidity CD8+ T cells in the context of low levels of antigen presentation.
In this Comment article, the authors alert us to recent studies of ancient DNA that advance our understanding of the origins of autoimmune disease, providing evidence that our disease risk has been shaped by pathogen-driven evolution.
A study published in Immunity shows that the mechanical force experienced by neutrophils migrating across endothelial barriers arms them for better bactericidal activity.
Genetic variants are identified in humans and viruses that influence the development of multiple sclerosis by shaping protective natural killer cell responses.
