A Membrane System for the Leukocyte Selective Recruitment
A formal description is developed for the phenomenon of leukocyte recruitment that plays a critical role in the immune response. Due to its complex nature and capability to rapidly adapt to the attack of infectious agents, the immune system may be considered a typical example of complex adaptive system .
Here the leukocyte selective recruitment, crucial in immunity, is modeled as a dynamical system of interactions between leukocytes and endothelial cells, where a special kind of membrane structure turns out to be a very useful tool in the formal analysis of the recruitment process. In our membrane system, besides the traditional rules for communication and transformation of P systems , rules are allowed for the expression of receptors, for adhesion between membranes, and for the encapsulation of a membrane inside another membrane.
