Transplant T CD4+ CCR7+ In Hematopoietic Stem Cells Allograft (CCR7-CD4-DPL)
Partial Selective Depletion in Lymphocytes Transplant T CD4+ CCR7+ in Hematopoeitic Stem Cells Allograft
This is a preclinical study prior to the establishment of a cell therapy protocol applicable to humans.
The main objective is to evaluate the decrease in alloreactivity of TCD4 + population by partial selective depletion of CD4 + CCR7 + graft to less than 50 % of CD4 + totals. To test the alloreactivity of donor T lymphocytes.
Panoramica dello studio
Descrizione dettagliata
This is a preclinical study prior to the establishment of a cell therapy protocol applicable to humans.
The main objective is to evaluate the decrease in alloreactivity of TCD4 + population by partial selective depletion of CD4 + CCR7 + graft to less than 50 % of CD4 + totals. To test the alloreactivity of donor T lymphocytes , T lymphocytes CD4 + CCR7 + donor will be stimulated by mature dendritic cells (DC) derived from recipient circulating monocytes in a mixed lymphocyte reaction model sensitized ( MLDCR ) , experiencing HLA -compatibility . This first step will confirm the results previously obtained in a situation incompatible HLA .
