Table 1 Correlative diferences in patients who survive versus patients who suecumb to Ebola virus infection dapted from Zampieri et. Al. Nature immunology 8:1 11 159 (2007) Nonlethal infection Prominent CDS T cell activation Above normal number of T cells Lethal infection No CD8 T cell activation Below normal number of T cells pies in serum Higher levels of viral genome copies in serum ble antibodies in blood at onset ofNo detectable antibodies in blood at onset of Lower levels of viral genome serumHigher symptoms symptoms 42. The presence of CD8 cells can explain the fact that patient survived the Ebola infection because the CD8 cells react with MHCII markers and destroy cells infected with viruses TRUE OR FALSE 43. The high number of T cells can explain the low number of viral genome in the serum because Te cells destr oy infected cells and CD4 cells release cytokines that enhance the immune system reaction against the viruses TRUE OR FALSE 4. The lack of antibodies indicated that there no clonal selection of B-lymphocyte by the antigen. TRUE OR FALSEExplanation / Answer
42. True
The patient survived ebola as presence of CD8 cells says that the infection was non lethal.These CD8 cells react with MHCII markers and destroy cells infected with viruses.
43. True
TC cells destroy infected cells and CD4 release cytokinesis which increases immunity.
44. True
Antibodies are produced by B cells. As there are no B cells, there's a lack of antibodies.
