Abstract

Immunology is the emerging research area which deals with the study of the immune system in any living organism. It is modelled through various computational and mathematical models to deal with the problem facing while to boost the immune system of an organism or to fight with the infectious disease at the very initial stage. Such models are very important for a better understanding of the complex behaviour of pathways inside the cells. The signalling pathways between the cells are complex and difficult to visualize in the immune system of human beings. So, it's important to study the function of these cells separately. T-cells and B-cells are an important part of the immune system and both have their own receptors and their different signalling pathways by which they deal with any antigens. In this paper, we discuss the B-cell receptor and its different signalling pathways downstream of the BCR. We designed a Petri-net model of the process of gathering antigens through B-cells independent of T-cell and the effect of that in the immune system of the organism. We will also discuss the contribution of BCR in the selection of the precursor tumour cell in CLL.
