Recirculation of germinal center B cells: a multilevel selection strategy for antibody maturation

M Or‐Guil, N Wittenbrink, AA Weiser… - Immunological …, 2007 - Wiley Online Library
Optimization of antibody affinity is a hallmark of the humoral immune response. It takes place
in hundreds of transient microstructures called germinal centers (GCs). Their function and …

[HTML][HTML] Adjusting the range of cell–cell communication enables fine-tuning of cell fate patterns from checkerboard to engulfing

S Schardt, SC Fischer - Journal of Mathematical Biology, 2023 - Springer
During development, spatio-temporal patterns ranging from checkerboard to engulfing occur
with precise proportions of the respective cell fates. Key developmental regulators are …

Statistical mechanics of clonal expansion in lymphocyte networks modelled with slow and fast variables

A Mozeika, ACC Coolen - Journal of Physics A: Mathematical …, 2016 - iopscience.iop.org
We use statistical mechanical techniques to model the adaptive immune system,
represented by lymphocyte networks in which B cells interact with T cells and antigen. We …

An evolutionary stability perspective on oncogenesis control in mature T-cell populations

HH Diebner, J Kirberg, I Roeder - Journal of Theoretical Biology, 2016 - Elsevier
Here we present a mathematical model for the dynamics of oncogenesis control in mature T-
cell populations within the blood and lymphatic system. T-cell homeostasis is maintained by …

Contributions to stochastic modelling of the immune system

H Mayer - 2016 - bonndoc.ulb.uni-bonn.de
During the past century, mathematical modelling of biological processes rapidly developed
into a field of high scientific interest. The diversity of mathematical approaches and …

[HTML][HTML] A major hindrance in antibody affinity maturation investigation: we never succeeded in falsifying the hypothesis of single-step selection

M Or-Guil, J Faro - Frontiers in Immunology, 2014 - frontiersin.org
Antibody (Ab) affinity maturation (AAM) referred originally to the observed increase in
average Ab affinity against a hapten (1). Later, it was found that AAM is associated with the …

A thermodynamic perspective of immune capabilities

E Agliari, A Barra, F Guerra, F Moauro - Journal of theoretical biology, 2011 - Elsevier
We consider the mutual interactions, via cytokine exchanges, among helper lymphocytes, B
lymphocytes and killer lymphocytes, and we model them as a unique system by means of a …

Nonequilibrium antigen recognition during infections and vaccinations

R Morán-Tovar, M Lässig - arXiv preprint arXiv:2304.02794, 2023 - arxiv.org
The immune response to an acute primary infection is a coupled process of antigen
proliferation, molecular recognition by naive B cells, and their subsequent proliferation and …

Temporal evolution of immunity distributions in a population with waning and boosting

MV Barbarossa, M Polner, G Röst - Complexity, 2018 - Wiley Online Library
We investigate the temporal evolution of the distribution of immunities in a population, which
is determined by various epidemiological, immunological, and demographical phenomena …

Moran-type bounds for the fixation probability in a frequency-dependent Wright–Fisher model

T Chumley, O Aydogmus, A Matzavinos… - Journal of mathematical …, 2018 - Springer
We study stochastic evolutionary game dynamics in a population of finite size. Individuals in
the population are divided into two dynamically evolving groups. The structure of the …
