Immunity (medical) - WikipediaImmunology is a branch of biology  that covers the study of immune systems  in all organisms. The term was coined by Russian biologist Ilya Ilyich Mechnikov ,  who advanced studies on immunology and received the Nobel Prize for his work in He pinned small thorns into starfish larvae and noticed unusual cells surrounding the thorns. This was the active response of the body trying to maintain its integrity. It was Mechnikov who first observed the phenomenon of phagocytosis ,  in which the body defends itself against a foreign body. Prior to the designation of immunity ,  from the etymological root immunis , which is Latin for "exempt", early physicians characterized organs that would later be proven as essential components of the immune system.
History of Immunology
Immunology is the study of the organs, cells, and chemical components of the immune system. The immune system creates both innate and adaptive immune responses. The innate response exists in many lower species, all the way up the evolutionary ladder to humans, and it acts through relatively crude means against large classes of pathogens.

In other languages Add links. History and Applications". Page Count:. Many of these cells are known as Antigen-Presenting Cells APCs because they break apart the ingested pathogen and display certain epitopes of the antigen on their surface.The prehistoric view of disease was that supernatural forces caused it, and that illness was a form of theurgic punishment for "bad deeds" or "evil thoughts" visited upon the soul by the gods or by one's enemies. Antibodies play an important role in containing virus proliferation during the acute phase of infection? The selection theory states that the body creates many different sidechains on antibodies, and loss of function functio laesa, and the antigen "selects" the correct antibody; in other amd. These included rednes.
Symbiont-mediated defenses are also heritable across host generations, despite a non-genetic direct basis for the transmission. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia. The cellular adaptive response Body cells are continuously processing protein derived from the internal cellular environment and presenting it in association with MHC class I receptors.

In unmatched donors this type of transfer carries severe risks of graft versus host disease. The Embryo Project. Horror Autotoxicus: The Concept of Autoimmunity 9. Body cells are continuously processing protein derived from the internal cellular environment and presenting it in association with MHC class I receptors.

Immunology has its origins in the study of how the body protects itself against infectious diseases caused by microorganisms, such as bacteria, viruses, protozoa, and fungi, and also parasitic organisms, such as helminth worms.

Written by an immunologist, A History of Immunology traces the concept of immunity from ancient times up to the present day, examining how changing concepts and technologies have affected the course of the science. It shows how the personalities of scientists and even political and social factors influenced both theory and practice in the field. With fascinating stories of scientific disputes and shifting scientific trends, each chapter examines an important facet of this discipline that has been so central to the development of modern biomedicine. With its biographical dictionary of important scientists and its lists of significant discoveries and books, this volume will provide the most complete historical reference in the field. Immunologists, molecular biologists, hematologists, historians of medicine and of science, individuals working in infectious disease.
This article provides a practical overview of innate and adaptive immunity, and describes how these host defense mechanisms are involved in both heath and illness. Background There are continuous advances in our current understanding of the immune system and how it functions to protect the body from infection! Immune dysfunction Important pathologies may result from immune dysfunction. Immune tissues All immune cells originate in the bone marrowbut an important set of immune cells T lymphocytes undergo maturation in an organ known as the thymus?
Obstetrics and gynaecology? Off of the basis for modern medicine, but the two major questions still to be answered were how did infection cause the degradation of ti. The basic principal of variolation was to deliberately cause a mild infection with unmodified pathogen. Namespaces Article Talk.
