Reversible Immortalization of Human Primary Cells by Lentivector-Mediated Transfer of Specific Genes
The success of active cancer immunotherapy entails a robust induction of tumor-reactive effector and memory CD8+ T cells. We compared the in vivo immunogenicity of the melanoma-associated antigen Melan-A(26-35) encoded by third-generation recombinant lentivector (rec. lv) or as peptide admixed with a strong adjuvant. Ex vivo analyses of immunized HLA-A2/H-2K(b) mice showed that rec. lv triggere...
Following trauma of the adult brain or spinal cord the injured axons of central neurons fail to regenerate or if intact display only limited anatomical plasticity through sprouting. Adult cortical neurons forming the corticospinal tract (CST) normally have low levels of the neuronal calcium sensor-1 (NCS1) protein. In primary cultured adult cortical neurons, the lentivector-induced overexpressi...
C-C chemokine receptor type 5 (CCR5) is utilized by human immunodeficiency virus (HIV) as a co-receptor for cell entry. Suppression of the CCR5 gene by artificial microRNAs (amiRNAs) could confer cell resistance. In previous work, we created a lentivector that encoded the polycistron of two identical amiRNAs that could effectively suppress CCR5. However, tandem repeats in lentiviral vectors led...
Polyglutamine disorders are inherited neurodegenerative diseases caused by the accumulation of expanded polyglutamine protein (polyQ). Previously, we identified a new guanosine triphosphatase, CRAG, which facilitates the degradation of polyQ aggregates through the ubiquitin-proteasome pathway in cultured cells. Because expression of CRAG decreases in the adult brain, a reduced level of CRAG cou...
