Witryna1. The organoids must retain all cell types of interest, including malignant and/or normal cells, stromal cells, and immune cells. The ratio and characteristics of these cells need to reflect those of the original tumour as well. Intuitively, the more cell types one includes, the more faithful the organoids are, compared to the in vivo tumour. Recent research suggests specific KIR-MHC class I gene interactions might control innate genetic resistance to certain viral infections, including HIV and its consequent development of AIDS. Certain HLA allotypes have been found to determine the progression of HIV to AIDS; an example is the HLA-B57 and HLA-B27 alleles, which have been found to delay progression from HIV to AIDS. This is evident because patients expressing these HLA alleles are observed to have lowe…
