Summary: |
Immunoproteasome subunits low-molecular mass polypeptide (LMP)2 and LMP7 affect Ag presentation by MHC class I molecules.
In the present study, we investigated the function of the third immunosubunit LMP10/multicatalytic endopeptidase complexlike (MECL)-1 ( 2i) in MECL-1 gene-targeted mice. The number of CD8 splenocytes in MECL-1 / mice was 20% lower than in wild-type mice. Infection with lymphocytic choriomeningitis virus (LCMV) elicited a markedly reduced cytotoxic T cell (CTL) response to the LCMV epitopes GP276–286/Db and NP205–212/Kb in MECL-1 / mice. The weak CTL response to GP276–286/Db was not due to an impaired generation of this epitope but was attributed to a decreased precursor frequency of GP276–286/Db-specific T cells. The expansion of TCR-V 10 T cells, which contain GP276–286/Db-specific cells, was reduced in LCMVinfected MECL-1 / mice. Taken together, our data reveal an in vivo function of MECL-1 in codetermining the T cell repertoire for an antiviral CTL response. |
