Of relevance to the HTLV field, our data conform and extend published findings on HAM pathogenesis at the molecular (IL6, CTCF, KDR-VEGF, TGFBR2), cellular (NK cells, monocytes)46-49, 46-49 and metabolic (lipids and chylomicrons) level. This evidence concerns the gene TGFBR2 and tropical spastic paraparesis.
