So named as they were initially found in the Bursa of Fabricius, B cells produce antibodies and are associated with humoral immunity (T cells are part of the cell-mediated immune response), and are an integral part of the adaptive immune system. They represent 20-30% of circulating lymphocytes.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This tutorial provides an overview of the immune system, concentrating on the roles played by B and T lymphocytes, and on the antigen-presentation system.

All animals possess a nonspecific defense system called the innate immune system, which includes macrophages in mammals. Vertebrates have an additional powerful immune response called adaptive immunity. This Click & Learn describes key elements of the adaptive immune system, including B cells and antibody molecules, helper T cells and cytotoxic T cells, and antigen presentation.

Covers cells and tissues of the immune system, lymphocyte development, the structure and function of antigen receptors, the cell biology of antigen processing and presentation including molecular structure and assembly of MHC molecules, lymphocyte activation, the biology of cytokines, leukocyte-endothelial interactions, and the pathogenesis of immunologically mediated diseases. Consists of lectures and tutorials in which clinical cases are discussed with faculty tutors. Details of the case covering a number of immunological issues in the context of disease are posted on a student Web site.

View the animation to see how one type of immune cell-the helper T cell-interprets a message presented at the surface of the cell membrane. The message is an antigen, a protein fragment taken from an invading microbe. A series of events unfolds that results in the production of many clones of the helper T cell. These identical T cells can serve as a brigade forming an essential communication network to activate B cells, which make antibodies that will specifically attack the activating antigen.

Immune Evasion: How Sneaky Pathogens Avoid Host Surveillance, Spring 2004

0.0 stars

This course is an advanced undergraduate seminar based upon discussions and critical analysis of primary literature in the field of immunology. Every infection consists of a battle between the invading pathogen and the resisting host. To be successful, a pathogen must escape the many defenses of the host immune system until it can replicate and spread to another host. A pathogen must prevent one of three stages of immune function: detection, activation, or effector function. Examples of disease specific immune evasion and the mechanisms used by pathogens to prevail over their host's immune systems are discussed. What these host-pathogen interactions reveal about the normal function of the immune system and about basic cell biological processes, such as protein maturation and degradation, are also considered.

This is a module framework. It can be viewed online or downloaded as a zip file.

As taught Autumn semester 2009.

Infections are a major cause of morbidity and mortality worldwide. The body fights infection through the functions of the immune system, whose power has been harnessed by the development of vaccination (immunisation).

Suitable for study at: Undergraduate levels 1 and 2.
