Rapamycin-Polarized Th1/Tc1 Autologous T LymphocytesNCIt concept
Preferred Label : Rapamycin-Polarized Th1/Tc1 Autologous T Lymphocytes;
NCIt synonyms : ex vivo anti-CD3/CD28 Costimulated, Rapamycin-Polarized Th1/Tc1 Autologous T Lymphocytes;
NCIt definition : A population of T lymphocytes polarized by rapamycin with potential immunomodulating
activity. The autologous T cells collected from the patient were co-stimulated with
antibodies to the T-cell cell surface proteins CD3 and CD28 and expanded ex vivo in
the presence of rapamycin, an immunosuppressive drug, and then infused back into the
same patient. Both CD3 and CD28 are required for full T-cell activation. These lymphocytes
expressed anti-apoptotic bcl-2 family member proteins (reduced Bax, Bak; increased
phospho-Bad); maintained mitochondrial membrane potentials; and displayed reduced
apoptosis. Adoptive transfer of this type of T cell potentially induces an anti-apoptotic
Th1/Tc1 effector phenotype by promoting autophagy.;
