Alteration of Mevalonate Pathway in Rat Splenic Lymphocytes: Possible Role in Cytokines Secretion Regulated by L-Theanine

Table 3

Effects of L-theanine treatment on the proliferation index (PI) and division index (DI) of the splenic lymphocytes subsets.

Item	Control	ConA	ConA + LTHs			P value
			0.25 mM	1 mM	4 mM
Total lymphocytes PI						0.191
Total lymphocytes DI						0.268
CD3^+CD4^+CD8^+PI						0.306
CD3^+CD4^+CD8^+ DI						0.685
CD3^+CD4^-CD8^- PI						0.378
CD3^+CD4^-CD8^- DI						0.093
CD3^+CD4^+CD8^- PI						0.481
CD3^+CD4^+CD8^- DI						0.242
CD3^+CD4^-CD8^+ PI						0.511
CD3^+CD4^-CD8^+ DI						0.581

Means in the same row not bearing a common superscript letter differ ; ConA = concanavalin A activation group; LTHs = L-theanine treatments.
