Chimerisms
WebDec 18, 2024 · First, several studies have tested for micro-chimerisms in the blood and skin of transplant recipients. This involves DNA extraction and amplification for the detection of donor-origin cells in order to find differences in HLA genotypes. In the case of a peanut allergic donor whose liver and kidney was given to a patient who developed food ... WebOur results do not show an impact of NK cells on the outcome of nonmyeloablative, even T cell-depleted, HCT across haplotype barriers using an anti-CD2 mAb. Our data also raise questions about the applicability of observations made with NK cell clones to the bulk NK cell repertoire in humans.
