Our natural smell, is produced, in part, by genes
called human leukocyte antigens (HLA).
Body scent is determined by a diverse set of genes
called Human Leukocyte Antigen (HLA), that form part of our immune system.
One factor: differences in surveillance proteins
called human leukocyte antigens (HLAs) embedded in our cells.
The cells or blood is then tested for special proteins,
called human leukocytes antigens (HLA).
