The clinical significance of the ABO blood group system extends beyond transfusion medicine and several reports have suggested an important involvement in the development of cardiovascular, oncological, and other diseases.
Along with their expression on red blood cells, ABO antigens are also highly expressed on the surface of a variety of human cells and tissues, including the epithelium, sensory neurons, platelets, and the vascular endothelium.
Recent research has also carved out a role for ABO blood group antigens in neuroscience. In fact, these antigens have been implicated in the development of olfactory nerve connectivity. In 1985, Mollicone et al. described the expression of B and H antigens on primary sensory cells of the rat olfactory apparatus and inner ear. Villarroya et al. suggested a possible role of the A gene or a gene closely linked to the ABO locus in the differential susceptibility to experimental allergic encephalomyelitis in rabbits. Another study, a further study demonstrated that the histo-blood group H carbohydrate is expressed by primary sensory neurons in both the main and accessory olfactory systems while the blood group A carbohydrate is expressed by a subset of vomeronasal neurons in the developing accessory olfactory system. This study showed that blood group sugars are involved in axon guidance events in the developing olfactory systems. A more recent report also provided evidence that the cell surface carbohydrate blood group A regulates the selective fasciculation of regenerating accessory olfactory axons.
Although blood group is not proximally associated with olfactory function of an individual more detail study and invasive study in controlled environment having adequate sample size are needed to reach a definite conclusion.
