| molecularNote | This transgene encodes the nucleoprotein (NP) from Armstrong's clone of the lymphocytic choriomeningitis virus (LCMV) regulated by the rat insulin promoter. Upstream of the NP cDNA are 660 base pairs of regulatory elements in addition to the rat insulin promoter. Downstream of the NP c-DNA is the SV40 small T-antigen intron and late polyadenylation signal. A stable transcript of the expected size was present in the pancreas, as determined by Northern blot analysis. RT-PCR analysis demonstrated that the transcript was expressed in pancreas and thymus, but not the spleen, brain, liver, kidney, heart, muscle or lung. In a T cell recognition assay, LCMV-specific cytotoxic T lymphocytes were shown to migrate specifically to the islets of Langerhans of transgenic mice, but not in control mice. |
