1 11162627 Using the reverse transcription PCR, we evaluated expression levels of various antigen presentation-related genes, including LMP2, LMP7, MECL-1, PA28alpha, PA28beta, TAP1, TAP2, and tapasin, in two oral squamous cell carcinoma cell lines, HSC5 and HSC7.
2 11162627 Expression levels of LMP2, MECL-1, TAP1, and TAP2 transcripts are reduced in both cell lines in comparison with a normal epithelial cell line.
3 11162627 Further, HSC5 and HSC7 show diminished expression of LMP7/tapasin, and PA28alpha/beta, respectively.
4 11162627 Surface expression of HLA-B alleles is down-regulated in both lines presumably due to low expression of TAP1/2.
5 11162627 Using the reverse transcription PCR, we evaluated expression levels of various antigen presentation-related genes, including LMP2, LMP7, MECL-1, PA28alpha, PA28beta, TAP1, TAP2, and tapasin, in two oral squamous cell carcinoma cell lines, HSC5 and HSC7.
6 11162627 Expression levels of LMP2, MECL-1, TAP1, and TAP2 transcripts are reduced in both cell lines in comparison with a normal epithelial cell line.
7 11162627 Further, HSC5 and HSC7 show diminished expression of LMP7/tapasin, and PA28alpha/beta, respectively.
8 11162627 Surface expression of HLA-B alleles is down-regulated in both lines presumably due to low expression of TAP1/2.
9 11739503 The proteasome regulator PA28alpha/beta was up-regulated, whereas PA28gamma was reduced in the liver of lymphocytic choriomeningitis virus-infected mice.
10 16515877 The ubiquitin-proteasome system (UPS) plays an indispensable role in inducing MHC class I-restricted CD8+ T cells and was exploited in the development of a DNA vaccine against the intracellular protozoan Toxoplasma gondii by constructing a chimeric DNA encoding a fusion protein between murine ubiquitin and the toxoplasma antigen SAG1.
11 16515877 Mice vaccinated with the DNA acquired potent protective immunity mediated by MHC class I-restricted CD8+ T cells against infection by the highly virulent Toxoplasma.
12 16515877 The accelerated degradation and induction of immunity were dependent on the UPS since mice lacking an immuno-subunit of 20S proteasome, LMP7, lost these functions, although they were independent of the proteasome regulator PA28alpha/beta complex.
13 18321749 Here, to develop a vaccine strategy taking advantage of activated CD8(+)T cells, we constructed a DNA vaccine, designated pGFP-TSA1, encoding a fusion protein linking GFP to a single CTL epitope of TSA1, a leading candidate for vaccine against T. cruzi.
14 18321749 Vaccination with pGFP-TSA1 enhanced epitope-specific cytotoxicity and IFN-gamma secretion by CD8(+)T cells.
15 18321749 When mice deficient in the proteasome activator PA28alpha/beta or the immunoproteasome subunits LMP2 and LMP7 were used, the protective immunity against infection was profoundly attenuated.
16 18321749 Our findings clearly demonstrate that vaccination with pGFP-TSA1 successfully induces protection dependent on CD8(+)T cell activation, in which immunoproteasomes play a crucial role.
