This was the very first report on VLA-1 / VCAM-1 interactions measured at the single-molecule level with AFM and at the same time between two living mammalian cells. Two later AFM reports on VLA-4/VCAM-1 lack citation and discussion of my original work, although they were clearly induced or even initiated by myself; interestingly, my years of initiating and pioniering such AFM experiments as independent and unpaid guest PI and exclusive sharing of know-how was neither acknowledged, nor cited in related reviews.
