Alterations of memory Th cell populations after intranasal immunization

Mouse group	Frequency (%) of CD45RB^l^o^w cells from the^a:
Mouse group	MEM	NP	NALT
P6+CT immunized	26.3 ± 4.2^*^,^†	67.2 ± 3.3^*^,^†	32.1 ± 2.8^*^,^†
CT immunized	17.6 ± 5.1^*	49.5 ± 4.5^*	26.7 ± 4.1^*
Control	6.7 ± 2.4	24.2 ± 3.7	14.3 ± 3.8

Frequency of CD45RB^low cells among CD4⁺ CD3⁺ T cells. Each value is expressed as the mean ± the SE and was obtained from a total of three experiments with 20 mice per group. *, P < 0.01 compared to the control; †, P < 0.05 compared to the CT-immunized group.
