The CD3 + CD4 + T cell count, CD3 + CD4+ T cell MM, CD3 + CD4 + CD28+ T cell count, CD3 + CD4 + CD28+ T cell MM, CD3 + CD8 + T cell count, CD3 + CD8+ T cell MM, CD3 + CD8 + CD28+ T cell count in HIV‐TB patients and HIV‐NTM patients were significantly lower than that in HIV‐infected patients (p < 0.05), as shown in Table 1. This evidence concerns the gene CD4 and tuberculosis.
