Abstract
We discuss in which sense the so-called regular pseudo-bosons, recently introduced by Trifonov and analyzed in some detail by the author, are related to ordinary bosons. We repeat the same analysis for pseudo-bosons, and analyze the role played by certain intertwining operators, which may be bounded or not.
