The functional significance of oncocytes (the "B" cells).
Oncocytes independently of their localization in this or that organ contain serotonin and high activity of succinate dehydrogenase. Hence oncocytes are not afunctionally dying cells, as was before believed, but a group of serotoninocytes, represented as a widely spread in the body diffused peripheral system of neuroendocrine system, which activity is bound with the function of the given biogenic monoamine. It seems reasonable to call oncocytes "B" cells after the first letter of the phrase "biogenic monoamines" which fully corresponds to their functional significance.
