Recent advances in xenotransplantation.

abstract：:Recent research has made great strides in uncovering the mechanisms by which the T helper 1 (Th1) cell gene expression program is established. In particular, studies examining the transcription factors T-bet, STAT1, and STAT4 have elucidated their roles in regulating Th1 signature genes, including Ifng, and have start...

abstract：:The molecular repertoire for innate recognition of bacterial pathogens has expanded rapidly in the past decade. These immunosensors include Toll-like receptors and the more recently defined NOD-like receptors (NLRs): NODs, NALPs, NAIP and IPAF. Toll-like receptors signal from the cell surface or endosome upon ligand b...
