体外研究

Healthy donors show both significantly less frequent T cell responses and lower numbers of pre-existing T cells to Secukinumab than other approved therapeutic antibodies used to treat plaque psoriasis.[1]

体内研究

The validation study using secukinumab shows similar results to the DSS-induced colitis model in Il17a−/− mice. WT mice that received secukinumab tend to lose less weight than those who do not. In the validation study using secukinumab, chronic colitis is induced in all the Rag2−/− mice that received T cells. Although statistical significance is not achieved in the comparison between the T cell transfer with secukinumab group and the group that does not receive secukinumab due to a small sample size, administration of secukinumab can not attenuate chronic colitis.[2]

推荐的实验操作(此推荐来自于公开的文献所以Selleck并不保证其有效性)

细胞实验:
- 合并
  • Objective: T Cell Assay
    Cells: Dendritic cells
    Concentrations: 1 μM
    Incubation Time: overnight
    Method: Dendritic cells (DC) are produced from plastic-adherent cells of PBMCs while CD4 T cells are isolated from PBMCs by using magnetic microbeads. The quality of the DCs is assessed by labelling of markers HLA-DR, HLA-A,B,C, CD14, DC-SIGN, CD86 and CD80. DCs are separately loaded overnight at 37 °C with keyhole limpet hemocyanin, KLH, used as a positive control (0.25 µM), or with the therapeutic antibodies secukinumab (1 µM) and matured with lipopolysaccharide (1 µg/mL). CD4 T cells (200 000/well) are stimulated by protein-loaded DCs (20,000/well) and cultured during 21 days. The number of antigen specific T cells is identified by interferon gamma (IFN-γ) ELISpot assay using an AID ELISpot Reader System.
