Subject of doctorate thesis: Establishing Hematopoietic Stem Cell Lacking A Human Leukocyte Antigens Haplotype from Induced Pluripotent Stem Cells Derived from Patients with Aplastic Anemia
M.Sc:“Internal Medicine”: Sohag Faculty of Medicine, Sohag University, Egypt. December, 2012
M.B.B.Ch.: Sohag Faculty of Medicine, Sohag University, Egypt. September, 2007.
General grade: Excellent with Honors
Interest: Hematology. Induced Pluripotent Stem Cell, immune pathophysiology Aplastic anemia, Hematopoietic Stem Cell Transplantation, leukemia, lymphoma, Cancer immunotherapy.
I am very interested in studing Induced Pluripotent Stem Cell, immune pathophysiology Aplastic anemia, Hematopoietic Stem Cell Transplantation, leukemia, lymphoma, Cancer immunotherapy and the immunopathophysilogy and maliganate evolution of hematological diseases using the iPSC technology
I studied the HLA allelic loss frequencies of AA patients with HLA-class I alleles lacking as a result of copy number neutral loss of heterozygosity of the short arm of chromosome 6 (6pLOH) from total 618 AA patients. Then, I cultured iPSCs with different HLA genotypes from monocytes of patients with acquired aplastic anemia (AA) possessing HLA-lacking leukocytes. Second, he induced HSC differentiation from these iPSC clones using different culture systems. Next, I investigated the genotype and the phenotype of iPSC-derived HSPCs (iCD34+ cells) with regard to cell surface markers and type of mutations, then studied the correlation of the different genotype and phenotype of iCD34+ cells with their proliferation and clonogenic potential.
These novel iCD34+ cells allowed to investigate the in vivo behavior and clonogenicity of AA iPSC-derived wild type (WT) and HLA(-) HSPCs without the influence of autologous mature T cells. For this study, genetically modified immunodeficient mice (BRGS mice) were available and reconstituted with HSPCs derived from two AA patients which included wild-type, 6pLOH(+), and HLA-B allele(-) (B4002[-] or B5401[-]) iCD34+ cells, negative control mice were included. The engraftment of human WT and HLA(-) iCD34+ cells at weeks 9, 10, and 12 after transplantation were extensively investigated by flow cytometry, PCR analysis and immunohistochemistry for determination the multilineage reconstitution of myeloid cells (CD33+), B cells (CD19+), and T cells (CD3+) in the bone marow, spleen, peripheral blood, and lymphoid cells in the thymus with no significant difference in the human-to-mouse chimerism ratio among the 3 groups.
I investigated with the other staff members of the hematology department, Kanazawa university and Fujita Health University the long standing question whether or not patient-derived cytotoxic T lymphocytes (CTLs) would be capable of killing autologous HSPCs using these iCD34+ cells with different HLA genotypes, and more importantly, if they would be able to discriminate between WT and HLA(-) iCD34+ cells in co-culture experiments. For this study, CTL lines were established from the same patient and cultured with iCD34+ cells, then we analyzed the T cell receptor (TCR) β repertoire of the CTL line capable of preferentially killing WT iCD34+ cells as well as T cells in the bone marrow of the patient obtained before immunosuppressive therapy. Stimulation of the patient’s CD8+ T cells with the WT iCD34+ cells generated a CTL line capable of killing WT iCD34+ cells but not killing B4002(-) iCD34+ cells. These data suggest that B4002(-) iCD34+ cells show a repopulating ability similar to WT iCD34+ cells when autologous T cells are absent, and CTL precursors capable of selectively killing WT HSCs are present in the patient’s peripheral blood
