The highest percentage of TIM-3 positive cells was observed on NK subpopulations both in MDS patients and in healthy volunteers: 33,01±23,89% vs 11,60±9,98% of CD16+CD56- NK cells, 13,16±18,80% vs 14,86±28,80% of CD16-CD56+ NK cells and 45,55±27,63% vs 28,17±24,30% of CD16+CD56+ NK cells respectively (S4 Table). Here, HAVCR2 is linked to myelodysplastic syndrome.
