Experimental timeline and Flow Cytometric evaluation of human immune cells reconstitutions in the peripheral blood of hu-BLT-hIL34 and hu-BLT mice. (A) Experimental design and timeline for the humanization of hIL34 transgenic mice and NOG mice by engrafting with human CD34+ hematopoietic stem and progenitor cells (HCSPs) and human fetal liver and thymic tissues, HIV-1 Ada infection of some mice in each group, and the evaluation of human myeloid and microglial cell reconstitution and HIV-1 infection in the CNS of euthanized mice using immunohistochemical staining (IHCS) and RNAscope in situ hybridization (ISH). (B) The representative flow cytometric dot plots of the peripheral blood mononuclear cells of a hu-BLT-hIL34 mouse (#1703) at the 4 months after transplantation, which were gated with hCD45+, hCD3+, hCD9+, and hCD14+ cells. (C) The percentage of hCD14+ myeloid cells in the peripheral blood of hu-BLT-hIL34 mice is significantly higher than that hu-BLT mice at the 4 months post transplantation. Each symbol represents an individual mouse, hu-BLT-hIL34 mice n=6, hu-BLT mice n=10; ****p < 0.0001.
