07-05-11摘要:AbstractThe role of activated microglia (MG) in demyelinating neurodegenerative diseases such as multiple sclerosis is controversial。 Here we show that high, but not low, levels of IFN- (a cytokin...
07-05-11摘要:Here, we show that zymosan, a stimulus for TLR2 and dectin-1, regulates cytokine secretion in DCs and macrophages to induce immunological tolerance。 First, zymosan induces DCs to secrete abundant ...
07-05-11摘要:In this study we describe what we believe to be a novel approach for tendon regeneration based on a specific signalling molecule, Smad8, which mediates the differentiation of mesenchymal stem cells...
07-05-11摘要:AbstractIn humans, sexual differentiation of the external genitalia is established at 7–12 weeks post conception (wpc)。 Here we show that the human fetal adrenal cortex synthesized cortisol much ...

07-05-11摘要:AbstractAntibodies against citrullinated proteins are specific and predictive markers for rheumatoid arthritis although the pathologic relevance of these antibodies remains unclear。 To investigate...
07-05-11摘要:AbstractHuman T cell leukemia virus type 1 (HTLV-1) infects both CD4+ and CD8+ lymphocytes, yet it induces adult T cell leukemia/lymphoma (ATLL) that is regularly of the CD4+ phenotype。 Here we sh...
