Textbook of Allergy for the Clinician 2nd edition PDF free download – The immune system is composed of an adaptive immune system and an innate immune system. The adaptive immune system distinguishes itself from the innate system by the following features: (a) Specificity of antigen recognition, (b) Diversity of the antigen receptor repertoire, (c) Rapid clonal expansion, (d) Adaptiveness to the changing environment and (e) Immunological memory. The innate system lacks fine specificity, has limited diversity and rudimentary memory but manifests rapid engagement. Lymphocytes are the primary cells of adaptive immunity; they include T cells, B cells and NK cells. Each individual cell type will be described in this chapter.
