Number of OVA-specific CD4⁺ T cells and total lymphocytes.

aILN: Iliac lymph nodes (subiliac, medial and external), CLN: cervical lymph nodes (superficial and posterior) and SPL: spleen. bAbsolute number of OVA-specific CD4+ T cells calculated as [(percentage of CD4+CFSE+×absolute number of lymphocytes)/100] for each lymphoid organ. OVA-specific T cells and total lymphocytes absolute numbers are to be multiplied×10∧3. cOne-way analysis of variance (ANOVA) and Tukey's post test were used to compare the number of OVA-specific CD4+ T cells present in lymphoid organs at different time points. *P<0.05; ***P<0.001.
