Statistical inference of the generation probability of T-cell receptors from sequence repertoires

A Murugan, T Mora, AM Walczak… - Proceedings of the …, 2012 - National Acad Sciences
Stochastic rearrangement of germline V-, D-, and J-genes to create variable coding sequence
for certain cell surface receptors is at the origin of immune system diversity. This process, …

Predicting evolution

M Lässig, V Mustonen, AM Walczak - Nature ecology & evolution, 2017 - nature.com
The face of evolutionary biology is changing: from reconstructing and analysing the past to
predicting future evolutionary processes. Recent developments include prediction of …

[HTML][HTML] High-throughput immune repertoire analysis with IGoR

Q Marcou, T Mora, AM Walczak - Nature communications, 2018 - nature.com
High-throughput immune repertoire sequencing is promising to lead to new statistical diagnostic
tools for medicine and biology. Successful implementations of these methods require a …

Flocking and turning: a new model for self-organized collective motion

…, L Parisi, E Silvestri, M Viale, AM Walczak - Journal of Statistical …, 2015 - Springer
Birds in a flock move in a correlated way, resulting in large polarization of velocities. A good
understanding of this collective behavior exists for linear motion of the flock. Yet observing …

Optimizing information flow in small genetic networks

G Tkačik, AM Walczak, W Bialek - Physical Review E, 2009 - APS
In order to survive, reproduce, and (in multicellular organisms) differentiate, cells must control
the concentrations of the myriad different proteins that are encoded in the genome. The …

Statistical mechanics for natural flocks of birds

…, E Silvestri, M Viale, AM Walczak - Proceedings of the …, 2012 - National Acad Sciences
Flocking is a typical example of emergent collective behavior, where interactions between
individuals produce collective patterns on the large scale. Here we show how a quantitative …

Precise tracking of vaccine-responding T cell clones reveals convergent and personalized response in identical twins

…, IZ Mamedov, T Mora, AM Walczak… - Proceedings of the …, 2018 - National Acad Sciences
T cell receptor (TCR) repertoire data contain information about infections that could be used
in disease diagnostics and vaccine development, but extracting that information remains a …

Maximum entropy models for antibody diversity

T Mora, AM Walczak, W Bialek… - Proceedings of the …, 2010 - National Acad Sciences
Recognition of pathogens relies on families of proteins showing great diversity. Here we
construct maximum entropy models of the sequence repertoire, building on recent experiments …

[HTML][HTML] Neoantigen quality predicts immunoediting in survivors of pancreatic cancer

…, E Patterson, R Monasson, T Mora, AM Walczak… - Nature, 2022 - nature.com
Cancer immunoediting 1 is a hallmark of cancer 2 that predicts that lymphocytes kill more
immunogenic cancer cells to cause less immunogenic clones to dominate a population. …

Self-regulating gene: an exact solution

…, D Schultz, GCP Innocentini, J Wang, AM Walczak… - Physical Review E, 2005 - APS
An exact steady-state solution of the stochastic equations governing the behavior of a gene
regulated by a self-generated proteomic atmosphere is presented. The solutions depend on …
