摘要:Abstract(#br)In the present report, three different shapes of chitosan-capped gold nanoparticles (nanospheres, nanostars, and nanorods) were synthesized to investigate the effects of shape on cytotoxicity and cellular uptake in cancer cells. Green tea extract was utilized as a re...

摘要:Summary(#br)Three subsets of invariant natural killer T (iNKT) cells have been identified, NKT1, NKT2, and NKT17, which produce distinct cytokines when stimulated, but little is known about their localization. Here, we have defined the anatomic localization and systemic dist...

摘要:Summary(#br)T follicular helper (Tfh) cells are essential for efficient B cell responses, yet the factors that regulate differentiation of this CD4 + T cell subset are incompletely understood. Here we found that the KLF2 transcription factor serves to restrain Tfh cell generation...

摘要:A prominent population of innate CD8 + T cells develops in the thymus of several gene-deficient mouse strains, including Itk , KLF2, CBP and Id3 . These cells have the phenotype and function of memory CD8 + T cells, without previous exposure to antigen. Surprisingly, the cytokine...
