Our paper on SARS-CoV-2 school-related measures prior to vaccination in Portugal has just been published in @commsmed.nature.com Thanks to Benedetta and Rey for all the hard work! www.nature.com/articles/s43...

Retrospective evaluation of school-related measures on pre-vaccination transmission dynamics of SARS-CoV-2 - Communications Medicine
Canfora, Escosio, et al. use an age-stratified transmission model fitted to Portuguese COVID-19 hospitalization and seroprevalence data to assess the impact of school closures before mass vaccination....

Our preprint about optimal vaccination, increasing life expectancy, age-dependent mortality, and waning of immunity is now available on MedRxiv. Thanks to @mvboven.bsky.social for inviting me to contribute. We use a PDE model in Julia to game out different scenarios. www.medrxiv.org/content/10.6...

Optimal vaccination in aging populations under age-dependent infection fatality risks
Background Vaccination programs have greatly reduced the burden of infectious diseases, particularly in childhood. As populations age, however, the burden of respiratory infections such as influenza A...

Cell-type- and state-resolved transcriptomics uncovers distinct T cell and monocyte dysregulation in multiple sclerosis
Roostaei et al. define cell-type- and state-specific transcriptional programs associated with immune dysregulation in multiple sclerosis. Integrating purified immune cell transcriptomics, network anal...

Our TRM modeling paper is now published in PLOS Computational Biology! In this paper, we fit dynamical (ODE) models to single-cell flow cytometry data using a variational autoencoder that has a GMM with time-dependent weights as prior. journals.plos.org/ploscompbiol...

A variational deep-learning approach to modeling memory T cell dynamics
Author summary After an influenza infection, antibodies provide strong protection—but only against the same strain. Because influenza rapidly mutates its surface proteins, this protection soon becomes...

Retrospective evaluation of school-related measures on pre-vaccination transmission dynamics of SARS-CoV-2
Schools are important settings for respiratory virus transmission and a major focus of pandemic control measures in the absence of effective pharmaceutical interventions. During the COVID-19 pandemic,...

StanConnects are a series of one-day online conferences for the application of Stan to specific areas. This year, we're kicking off with Stan for biology (broadly defined), co-organized by @ericnovik.bsky.social and @vianeylb.bsky.social, on 30 May '25!! stanbio.org

Nearly 20 years ago, theory predicted that evolution can evolve “mutation sensors” to improve evolvability. Michael Barnett et all et al. now show this in a beautiful experiment! ❤️ www.science.org/doi/10.1126/...

Experimental evolution of evolvability
Evolvability—the capacity to generate adaptive variation—is a trait that can itself evolve through natural selection. However, the idea that mutation can become biased toward adaptive outcomes remains...

In this preprint we quantify how resident-memory CD4 T cells are maintained in skin and lamina propria, and where they come from. We did this with a fate reporter mouse model, and of course Bayesian ODE models implemented in Stan. doi.org/10.1101/2024...

Tissue resident memory CD4+ T cells are sustained by site-specific levels of self-renewal and replacement from precursors
Tissue-resident memory T cells (TRM) protect from repeated infections within organs and barrier sites. The breadth and duration of such protection is defined at minimum by three quantities; the rate a...

Our CD4 memory T cell paper is finally published in PLOS Biology (doi.org/10.1371/jour...). Congratulations to Elise Bullock and other co-authors!

The dynamics and longevity of circulating CD4+ memory T cells depend on cell age and not the chronological age of the host
The quality and longevity of CD4+ effector and central memory T cells change with age in mice. This study shows that these cells have longer lifespans and become more quiescent when the organism ages,...

I this preprint we model lung memory T cell dynamics following influenza infection, and fit such models to "single cell" flow cytometry data directly. The idea is to identify T cell populations and their dynamics simultaneously. www.biorxiv.org/content/10.1...
