In this model we condider a B cell and its surrounding area and simulate movement and binding of receptors and ligands. The receptors can either be membrane bound (B cell receptors) or soluble (antibodies). Furthermore, receptors can either have a simple spherical shape or a more realistic Y-shape. This allows comparison of the binding dynamics with regard to the dimensionality of motion (membrane-bound vs. soluble), morphology and the binding valency.
This model is a variant of the previously developed SBM of whole-blood infection assay. While in the previous model a spontaneous immune evasion mechanism (A) was implemented in this model immune evasion was caused by PMN molecule secretion (B).
The state-based model (SBM) allow to simulate the interplay between innate immune cells, such as monocytes and PMN, and Candida albicans and to quantify immune reaction rates like phagocytosis and killing rates. It is implemented in C++.
This model comprises a hybrid agent-based model of a single human alveolus. The alveolus is represented in a realistic to-scale representation and contains the cell types of alveolar epithelial cells (AEC) of type 1 and 2 as well as the pores of Kohn (PoK). A single A. fumigatus conidium in inserted into the alveolus and the AEC, where the conidium is located secretes chemokines. Chemokine secretion is modelled using the partial differential equation of the diffusion equation and numerically

Adaptation of the previously developed virtual infection model of Aspergillus fumigatus in a *human* alveolus.
This model comprises a hybrid agent-based model of a single murine alveolus. The alveolus is represented in a realistic to-scale representation and contains the cell types of alveolar epithelial cells (AEC) of type 1 and 2 as well as the pores of Kohn (PoK).
Furthermore, in this model, depending on the infection dose multiple A. fumigatus conidium are inserted into the alveolus and the
