Human T-cell leukemia virus type 1 (HTLV-1) and HTLV-2 are distinct oncogenic retroviruses that infect several cell types but display their biological and pathogenic activity only in T cells. Previous studies have indicated that in vivo HTLV-1 has a preferential tropism for CD4+ T cells, whereas HTLV-2 in vivo tropism is less clear but appears to favor CD8+ T cells. Both CD4+ and CD8+ T cells a...
Methods Population-based and “deep” V3-loop sequencing were performed in 53 MVC recipients in the MERIT, MOTIVATE and A4001029 studies who spontaneously changed tropism readout by the original Trofile assay between screening and baseline (~4-8 weeks) and 72 randomly sampled patients who did not change. Tropism was inferred by “geno2pheno” with previously defined cutoffs: 2% X4 prevalence with a...
Expression of the human poliovirus receptor (PVR) in transgenic mice results in susceptibility to poliovirus infection. In the primate host, poliovirus infection is characterized by restricted tissue tropism. To determine the pattern of poliovirus tissue tropism in PVR transgenic mice, PVR gene expression and susceptibility to poliovirus infection were examined by in situ hybridization. PVR RNA...
