abstractText | Lymphotoxin alpha (LT alpha)-deficient mice revealed critical roles for LT alpha in lymphoid organogenesis, but it is not clear whether LT alpha functions through an LT alpha homotrimer (LT alpha3) or LT alpha/beta heterotrimers. We generated LTbeta-deficient mice and found them to lack Peyer's patches, peripheral lymph nodes, splenic germinal centers, and follicular dendritic cells. Unlike LT alpha-deficient mice, LT beta-deficient mice had cervical and mesenteric lymph nodes. Furthermore, the mesenteric lymph nodes had germinal center-like regions, although these structures appeared to lack follicular dendritic cells. The absence of cervical and mesenteric lymph nodes in LT alpha-deficient mice, and yet their presence in LT beta-deficient mice and in mice deficient in tumor necrosis factor receptor types I and II, suggest that LT alpha3 may signal via an as yet unidentified receptor. |
