abstract = {Human cytomegalovirus (HCMV) is a relevant pathogen,
especially for individuals with impaired immunity.
Harnessing potent immune antagonists, HCMV circumvents
sterile immunity. Given that HCMV prevents the upregulation
of human leukocyte antigen (HLA)-DP and HLA-DR, we screened
a library of HCMV genes by co-expression with the HLA class
II (HLA-II)-inducing transcription coordinator class II
transactivator (CIITA). We identified the latency regulator
pUS28 as an interaction factor and potent viral antagonist
of CIITA-driven expression of CD74, HLA-DR, HLA-DM, HLA-DQ,
and HLA-DP. Both wt-pUS28 and a mutant incapable of inducing
G protein-coupled signaling (R129A), but not a mutant
lacking the C-terminus, drastically reduced the CIITA
protein abundance post-transcriptionally. While control CD4
+ T cells from HCMV-seropositive individuals vigorously
responded to CIITA-expressing cells decorated with HCMV
antigens, pUS28 expression was sufficient to inhibit HLA-II
induction and immune recognition by HCMV-specific CD4 + T
cells. Our data uncover pUS28 to be employed by HCMV to
evade HLA-II-mediated recognition by CD4 + T cells.},
