CLINICAL IMMUNOLOGY & SEROLOGY A LAB PERSPECTIVE
CHAPTER 1 (QUESTIONS AND CORRECT DETAILED ANSWERS
2026TH EDITION)
Summary 1 - ANS -* immunology has its roots in the study of immunity - the
condition of being resistant to disease
* Jenner performed the first vaccination against smallpox by using cowpox
* Louis Pasteur is considered the father of immunology for his use of attenuated
vaccines
* Metchnikoff was the first to observe phagocytosis - meaning cells that eat cells
* Immunity has two branches. Innate Immunity is the ability of the body to resist
infection through means of normally present nonspecific functions. Adaptive
Immunity is characterized by specificity, memory and dependence upon
lymphocytes
* all blood cells arise in the bone marrow from hematopoietic stem cells
, * the five principal types of leukocytes are neutrophils, eosinophils, basophils,
monocytes and lymphocytes
* tissue cells involved in the innate immune response and are actively phagocytic
include neutrophils, monocytes, macrophages, and dendritic cells
Summary 2 - ANS -* lymphocytes are he key cells involved in the adaptive immune
response
* CD stands for clusters of differentiation, which are types of proteins found on
cell surfaces that can be used for identification of specific cells and cell stages
* B cells are a type of lymphocyte that develop in the bone marrow and are
capable of secreting antibody when mature. They can be identified by the
presence of CD19 and surface antibody
* T cells acquire their specificity in the thymus and consist of two subtypes: CD4+,
which are mainly helper or regulatory T cells, and CD8+, which are cytotoxic T cells
