The Role of NK Cells in the Control of Viral Infection in HTLV-1 Carriers

Table 2

NK and NKT cell frequencies in HTLV-1-infected subjects.

Frequency of cells (%)	Seronegative individuals (SN) ()	HTLV-1 carriers (HC) ()	HAM/TSP ()
CD56^+CD3^-	7.9 (4.5-15.3)	8.9 (2.8-15)	5.8 (1.9-11.7)^a,b
CD56^+CD16^+	10.1 (5.3-16.2)	10.7 (3.2-22.9)	7.2 (1.8-15.8)^a,b
CD56^+	16.4 (11.6-23.8)	13.3 (6.4-26.4)	11.2 (4.6-19.4)^a,b
CD56^dim	12.9 (9-21.3)	12.2 (5-27.4)	9.5 (3.4-19.4)^a,b
CD56^bright	0.9 (0.5-3.4)	0.8 (0.07-1.5)	0.7 (0.2-1.3)
NKT	6.4 (3.5-11.5)	4.6 (2.2-14.7)	4.1 (1.9-9.7)

The Mann-Whitney test was used for statistical analyses. Data are represented by median (minimal and maximal values); ^aSN × HAM/TSP (); ^bHC × HAM/TSP ().
