Function of the immune system
This article, which forms part of the life sciences series, explores the function of the immune system. It is important that nurses understand how the immune system works and its role in the prevention of infection. Innate and adaptive immunity are described and the differences between these two types of immune response are discussed. The acquisition and development of a competent immune system are also explored.

- "This means that from a danger theory perspective, the immune system only responds to foreign cells which are dangerous or harmful to the body. Matzinger introduced the danger theory , . In brief, when a self cell is damaged by an antigen, the self cell sends out a stress signal which indirectly co-stimulates an HTC. "

ABSTRACT: The artificial immune system (AIS) is inspired by the functioning of the natural immune system. There are different theories with regards to the organisational behaviour of the natural immune system. One of these theories is the network theory. In this paper a novel network based AIS model is proposed. The proposed Local Network Neighbourhood Artificial Immune System (LNNAIS) is inspired by the network topology of lymphocytes to learn the antigen structure from one another. LNNAIS has a different interpretation of the network theory compared to existing network based AIS models. LNNAIS uses a concept of an artificial lymphocyte (ALC) neighbourhood to determine the network links between the ALCs. The purpose of this paper is to provide a proof of concept that an artificial lymphocyte (ALC) neighbourhood can cluster data in a dynamic environment. LNNAIS only requires one pass through the training data of antigen patterns for clustering.
