1. A Snapshot of the Immune System

The host, via its immune system, has the capacity to recognize materials as foreign to itself and to neutralize, eliminate, or metabolize them with or without injury to its own tissue(s). This ability to differentiate ‘self’ from ‘nonself’ constitutes the basic hallmark of the immune response and the basis for an understanding of clinical immunology Read More

1. Primary Immunodeficiencies

Introduction to Immune Deficiency Disorders The immune deficiency conditions are a group of disorders that result from one or more abnormalities of the immune system and that manifest clinically as an increased susceptibility to infection. This group of human diseases was ushered in by a single seminal observation made by a clinician who carefully studied Read More

9. T cell mediated autoimmune diseases

Introduction Patients with T cell defects can present with a variety of organ specific autoimmune diseases (e.g., type 1 diabetes mellitus in infancy, hypothyroidism, and Addison’s disease) caused by the attack on these organs by the patient’s own immune cells. The basis for these clinical complications is unclear, but are thought to be caused by Read More

Immunity to Malaria

Malaria is a vector borne disease, caused by an intracellular parasite, the protozoan Plasmodium spp. It affects most tropical areas of the world (Figure 1), where mosquitos of the Anopheles genus are present. Young children and pregnant women are especially vulnerable to malaria infection, and most of the mortality occurs among children under 5 years Read More

Antibody Structure and Classes

History of Immunoglobulin Molecules Take a look at our Timeline – History of Immunoglobulin Molecules Immunoglobulin Structure The immunoglobulins are a family of glycoproteins, and based on chemical and structural differences are classified in five distinct classes of molecules called isotypes that are named IgM, IgG, IgA, IgD, and IgE. Each immunoglobulin has two small Read More
