HIV-1 transmission and cytokine-induced expression of DC-SIGN in human monocyte-derived macrophages.

abstract：:An accessory cell line, designated line A, was generated from bone marrow stem cells which differentiated in vitro in response to colony-stimulating factor (CSF) in substratum cultures. The cells were found to constitutively secrete large amounts of CSF, the activity of which was neutralized by anti-CSF-1 antibodies. ...
