The immune system is a collection of billions of cells that travel through the bloodstream. They move in and out of tissues and organs, defending the body against foreign bodies (antigens), such as bacteria, viruses and cancerous cells.There are two types of lymphocytes :B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria. T cells (see picture opposite) - if the invader gets inside a cell, these (T cells) lock on to the infected cell, multiply and destroy it.here are two types of lymphocytes : B cells-produce antibodies which are released into the fluid surrounding the bodyâs cells to destroy the invading viruses and bacteria.

Gillespieâs algorithm (Gillespie, 1977) is a way of im-. plementing consistently this probabilistic description of a biological system. The probabilistic. description by its very nature applies to single cells. The connection with molecular concentra-.
The algorithm here is a cake recipe. You can find the algorithm to solve this problem in a cookbook! We canât find the park. Choose. You selected. We canât find the park. The algorithm you need is a set of directions to get to the park! There might be different ways to the park so you can have different algorithms. We need to build a toy. Choose. You selected. We need to build a toy. The algorithm to follow here is the list of instructions that tell you how to make the toy.
