Immunology extravation question The extravasation of neutrophils and lymphocytes occurs by generally similar mechanisms, although some differencesdistinguish the two processes. Which statements are true about lymphocyte extravasation?Naive lymphocytes are confined to the secondary lymphatic system by expression of the surface protein CD62L whichrecognizes HEV addressins.The adhesion step requires chemokine activation.Extravasation follows the order of chemoattraction, adhesion, rolling, and transmigration.Extravasation follows the order of rolling, activation, adhesion, and transmigration.The transmigration step requires chemokine activation.CCR7 is an essential chemokine receptor that guides lymphocyte extravasation into tissues during an immuneresponse.

Briefly describe the effector functions of the following subsets of CD4* helper T lymphocytes and distinguish their cytokine profiles: уThi cell ii)Th2 cell
CD8 T cells in a culture are analyzed for their ability to produce the cytokine IFN-g, and the numbers of IFN-g-producing CD8 T cells are quantified. As a control, T cells are also stimulated with an irrelevant non-viral peptide (ova) plus dendritic cells. The results are shown in the figure below. Why is the T cell response different between the two lymph node populations?
For each of the following situations, indicate which type(s) of lymphocyte(s), if any, would be expected to proliferate rapidly in lymph nodes and where in the nodes they would do so. Nomal mouse with a viral infection (a) (b) (c) Neonatally thymectomized mouse immunized with a protein antigen Neonatally thymectomized mouse immunized with the thymus-independent antigen bacterial lipopolysaccharide (LPS), which does not require the aid of THcells to activate B cells.
Secondary lymphoid organs, such as the lymph nodes, spleen, and mucosa-associated lymphoid tissues, each have distinct features that are important for their role in initiating immune responses focused on different anatomical compartments (i.e., the peripheral tissues, the blood, or the gastrointestinal tract, respectively). Yet these organs share some overall structural features, such as distinct T-cell and B-cell zones. One major difference between these organs is: The presence versus the absence of macrophages and dendritic cells Their function in bringing rare naive lymphocytes into contact with their specific antigen The ability of lymphocytes to enter the organ from the blood The mechanism by which antigens or pathogens enter the organ The ability of naïve T cells to be activated and proliferate in the organ
What is the function of interleukin-7 in lymphocyte formation? View Available Hint(s) Hint 1. Development of Lymphocyte Types opened hint The different lymphocyte types are all derived from lymphatic stem cells. Their ultimate fate depends upon the location where they mature and the signals that they receive. What is the function of interleukin-7 in lymphocyte formation? It supports the differentiation of lymphoid stem cells into NK, B, and T cells. It supports the differentiation of pluripotential stem cells into lymphoid stem cells. It supports the differentiation of pluripotential stem cells into NK, B, and T cells. It supports the differentiation of lymphoid stem cells into NK cells and B cells.

Some primitive organisms, such as invertebrates, have no lymphocytes and thus lack an adaptive immune system, but they have somecomponents of an innate immune system, including phagocytes andcertain protective proteins. What are some general features of innateimmunity that make it very valuable to organisms lacking more specific antibody- and cell-mediated responses? What are some disadvantages to having only an innate immune system?
