Multidrug resistance proteins [MRPs and P-glycoprotein (Pgp)] are members of the family of ATP-binding cassette (ABC) transport proteins, originally described as being involved in the resistance against anti-cancer agents in tumour cells. These proteins act as ATP-dependent efflux pumps and have now been described in normal cells where they exert(More)
P-glycoprotein (Pgp) and multidrug resistance protein 1 (MRP1) are members of the ATP-binding cassette (ABC) family of transporter proteins. Both molecules are membrane-associated, energy-dependent efflux pumps with different substrate selectivity and they may play a role in the activation, differentiation and function of haematopoietic cells.

Aging modifies a number of functional and phenotypic parameters of cells from the immune system. In this study, the activities of two members of the superfamily of ATP-binding cassette (ABC) transport proteins, ABCB1 and ABCC (measured by rhodamine 123 efflux and Fluo-3 efflux respectively), were compared in murine bone marrow cells and thymocytes of young(More)
The human T cell lymphotropic/leukaemia virus type I (HTLV-I) causes HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). The multidrug resistance associated protein 1 (ABCC1) plays multiple functions in physiopathologic responses. The expression and activity of ABCC1 was studied in T lymphocytes from uninfected and HTLV-I-infected(More)
