TI  - Bidirectional transendothelial migration of monocytes across hepatic sinusoidal 
      endothelium shapes monocyte differentiation and regulates the balance between 
      immunity and tolerance in liver.

AB  - Monocytes are versatile cells that can fulfill proinflammatory and 
      anti-inflammatory functions when recruited to the liver. Recruited monocytes 
      differentiate into tissue macrophages and dendritic cells, which sample antigens 
      and migrate to lymph nodes to elicit T-cell responses. The signals that determine 
      monocyte differentiation and the role of hepatic sinusoidal endothelial cells 
      (HSECs) in this process are poorly understood. HSECs are known to modulate T-cell 
      activation, which led us to investigate whether transendothelial migration of 
      monocytes across HSECs influences their phenotype and function. Subsets of 
      blood-derived monocytes were allowed to transmigrate across human HSECs into a 
      collagen matrix. Most migrated cells remained in the subendothelial matrix, but 
      ~10% underwent spontaneous basal to apical transendothelial migration. The 
      maturation, cytokine secretion, and T-cell stimulatory capacity of reverse 
      transmigrating (RT) and subendothelial (SE) monocytes were compared. SE monocytes 
      were mainly CD16(-) , whereas 75%-80% of RT monocytes were CD16(+) . SE monocytes 
      derived from the CD14(++) CD16(-) subset and exhibited high phagocytic activity, 
      whereas RT monocytes originated from CD14(++) CD16(+) and CD14(+) CD16(++) 
      monocytes, displayed an immature dendritic cell-like phenotype (CD11c(pos) 
      HLA-DR(pos) CD80lo CD86lo ), and expressed higher levels of chemokine (C-C motif) 
      receptor 8. Consistent with a dendritic cell phenotype, RT monocytes secreted 
      inflammatory cytokines and induced antigen-specific CD4(+) T-cell activation. In 
      contrast, SE monocytes suppressed T-cell proliferation and activation and 
      exhibited endotoxin tolerance. Transcriptome analysis underscored the functional 
      differences between SE and RT monocytes. CONCLUSIONS: Migration across HSECs 
      shapes the subsequent fate of monocytes, giving rise to anergic macrophage-like 
      cells in tissue and the release of immunocompetent pre-dendritic cells into the 
      circulation.
