title: [Interaction between member LIGHT of TNF superfamily and SOCS3, which respond to induce the differentiation and maturation of dendritic cell].
abstract: OBJECTIVE
  To detect the relation between the member LIGHT of TNF superfamily and the suppressor of cytokine signaling 3 (SOCS3), and to investigate the effect of SOCS3 on dendritic cell (DC) maturation induced by LIGHT.
  
  
  METHODS
  Bone marrow-derived DC (BMDC) was generated from mouse bone marrow monocyte by culturing with rmGM-CSF, rmIL-4 in vitro. SOCS3 mRNA in BMDC was analyzed by RT-PCR, and the protein of SOCS3 was measured by Western blot. After blocking the SOCS3 expression with the specific anti-sense oligonucleotide, we applied the flow cytometry to measure the expression of CD86 and CD40 on DC for making clear whether the silence of SOCS3 would regulate the LIGHT-stimulated DC maturation.
  
  
  RESULTS
  With the effect of LIGHT, the level of SOCS3 mRNA and protein in BMDC sharply increased. The specific antisense oligonucleotide could effectively block SOCS3 mRNA expressing in BMDC with the ratio of 49% and block SOCS3 protein expression with the ratio of 45%. Compared with SOCS3-unblocked DC, the SOCS3-blocked BMDC with stimulation of LIGHT showed higher CD40 and CD86 (P < 0.05).
  
  
  CONCLUSIONS
  LIGHT enhances the expression of SOCS3 during stimulating BMDC maturation. As more sensitive to LIGHT, the SOCS3-blocked BMDC is driven to more mature. SOCS3 presents a negative regulation mechanism in BMDC maturation induced
