Many of the receptors for the general senses are associated with the skin (figure 9.2); others are associated with deeper structures ...
WebbEach T cell that is activated has a specific receptor “hard-wired” into its DNA, and all of its progeny will have identical DNA and T cell receptors, forming clones of the original T cell. Figure 21.19 Clonal Selection and Expansion of T Lymphocytes Stem cells differentiate into T cells with specific receptors, called clones. WebbCytokine receptors have also been shown to have a key role in the pathophysiology of human immunodeficiency virus (HIV) infection. It has been shown that the chemokine receptors, CCR-5 and CCR-3, act as cofactors for virus entry into macrophages, whereas the LESTR/SDF-1 receptor is required for the infection of T cells.
WebbDescribe receptor-mediated endocytosis. Receptors bind specific ligand within coated pits to form endosomes. The endosome becomes acidified and enriched with acid hydrolyses, becoming the late endosome, and ultimately lysosome. Describe phagocytosis.

WebbAbstract. Olfactory receptors mediate the primary interaction of the olfactory brain with the external world. Any odor stimulus is initially represented as activation of one to many different olfactory receptors. Vice versa, anything that binds and activates an olfactory receptor is as per definition an odor, or odorant, as the single compounds ...
