Folk medicine has long employed leaves from Eriobotrya japonica Lindl. (Rosaceae) (LEJ) as relieving many diseases including chronic bronchitis and high fever. In this study, we investigated the immunomodulatory effects of leaves from LEJ water extracts (LEJE) in LP-BM5 murine leukemia viruses (MuLV)-induced immune-deficient animal model. Dietary supplementation of LEJE (100, 300, 500 mg/kg) began on the day of LP-BM5 MuLV infection and continued for 12 weeks. Dietary supplementation of LEJE inhibited LP-BM5 MuLV-induced splenomegaly and lymphadenopathy. Moreover, LEJE attenuated reductions of T- and B-cell proliferation and Th1/Th2 cytokine imbalance in LP-BM5. We found that dietary supplements of LEJE suppressed the hypergammaglobulinemia by ameliorating LP-BM5 MuLV infection-induced B-cell dysfunction and production of pro-inflammatory cytokines. We suggest that Eriobotrya japonica may have beneficial immunomodulatory effects, improving the balance of Th1/Th2 cytokines and anti-inflammatory effects.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008214	Lymphocytes	White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS.	Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
