WebSep 10, 2013 · In order to study the cooperation between the CD4 and CD8 T cells, each is engineered separately before they are mixed together to try to get an optimal effect on the tumor. In the 2494 study, patients with b-cell malignancies are treated with CAR-modified T cells taken from a donor’s blood instead. Turtle says the 2949 study is done in the ... WebThe majority of naive or reactive T cells seen in bone marrow, peripheral blood, bone marrow, and other tissues express either CD4 (for example, helper or regulatory T cells) or CD8 (for example, cytotoxic T cells). Absence of both CD4 and CD8 can also be seen; for example, gamma-delta T cells often lack expression of both of these antigens.
