NCIt definition : A preparation of cytotoxic, autologous acute myelogenous leukemia (AML)-reactive T
lymphocytes (CTL), with potential immunomodulating and antineoplastic activities.
The autologous cultured AML-specific CTLs are prepared using a specific AML-CTL culture
method. Autologous peripheral blood lymphocytes are taken from an AML patient and
the autologous AML blasts are treated with granulocyte macrophage colony-stimulating
factor (GM-CSF) and interleukin 4 (IL-4), both of which promote ex vivo differentiation
of AML blasts into dendritic cells (DCs). In the same culture, T cells are treated
and activated by low-dose interleukin 2 (IL-2), and expanded using anti-CD3. This
results in cultured AML-reactive CTLs which are administered back into the patient
after autologous hematopoietic stem cell transplant (AHSCT). The autologous cultured
AML-specific CTLs may eradicate residual AML cells.;
