CD4 and urogenital neoplasm: Interestingly, this study predicted that 5 immunophenotypes were negatively correlated with the risk of prostatitis, with the specific immunophenotypes being SSC-A on NKT, HLA-DR on DC, absolute count of CD14– CD16+ monocytes, HLA-DR+ CD4+ %T cells, and HLA-DR+ CD4+ % lymphocytes, respectively, which might be involved in the negative regulation of prostatitis.
