immunology: Indicate what step is correct (Select all that apply) Lymphocytes travel through the body in the lymph as well as the blood Lymphocytes leave the blood through the walls of fine capillaries in 2ry lymphoid organs After spending some time in the LN, lymphocytes leave in the efferent lymph Lymphocytes return to blood at the subclavian vein A lymphocyte after encounter an antigen to which its receptor binds, stops recirculating. The spleen has no connection to the lymphatic system...
For each description below, select the cell type or tissue type to which it refers, using the drop down menu for each. It is possible that a cell or tissue type from the list may not be used at all, or may be used more than once. choices: dendritic cell, lymphocyte, antibody, spleen, lymph node, monocyte, thymus, neutrophil, hematopoietic stem cell, erythrocyte, bone marrow and m (microfold cell). a. major cell type presenting antigen to naive helper T cells b....
answer all the questions answering one question is not helpful 1. A helper T cell is capable of helping another cell because it expresses a protein on its surface that binds to a different protein on the surface of the cell being helped. What are these proteins (on the T cell, and on the cell being helped)? CD28, and B7 TNF, and TNFR Class I MHC, and TCR CD40L, and CD40 CTLA-4, and B7 2. Helper T cells are restricted...
