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.
By the end of this section, you will be able to:Explain adaptive immunityCompare and contrast adaptive and innate immunityDescribe cell-mediated immune response and humoral immune responseDescribe immune tolerance
This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"In endocytosis, the cell plasma membrane folds inward and pinches off to form intracellular vesicles. Originally, endocytosis was thought to primarily facilitate feeding and pathogen neutralization, but it is now known to regulate numerous processes in eukaryotic cells, such as signaling, membrane composition, mitosis, movement, and morphogenesis. Endocytosis also plays many roles in T cells through both clathrin-dependent and clathrin-independent mechanisms. For example, clathrin-mediated endocytosis regulates the receptors on the plasma membrane and internalizes α/β-type T cell antigen receptors (TCRs). Through clathrin-independent pathways, endocytosis internalizes TCRζ and the IL-2Rβ complex and recycles TCRαβ. Clathrin-independent endocytosis also helps T cells bind to antigen-presenting cells of the immune system and ingest pathogens and other foreign materials to aid in host defense and immune surveillance..."
